  1. Afternoon People, Have been sifting through stuff all day and still can't decide what to do. Situation is this....Currently running pressurized co2 in my 240l planted tank. Everything seems to be going bananas and was previously using a ceramic diffuser up the intake of a small filter....which is now broken . So the single cermaic disc isn't obviously the best method to absorb the co2 into the water column so I'm after opinions on the following options. Option 1: DIY reactor - http://www.qsl.net/w2wdx/aquaria/reactor.html - using a cheap power head $20, the end pipe of a gravel vac, a filter for the intake of the power head and something at the bottom of the gravel vac pipe(course filter probably) with the ceramic diffuser 3/4 of the way down the gravel vac. Advantage: cheap-ish maybe $40 total. Disadvantage would be that it's home made, if I have the power up too high could spit substrate and dirt everywhere and ruin my tank.....and it would look a bit bulky but will probably hide behind plants. Option 2: Tunze diffuser, basically same principle as above only it uses a weak power head and I've read mixed reviews. Adv: all in one con: more expensive $60 Option 3: Combo system using a power head and an inline reactor - Pro: Should work really well, Con: larger foot print maybe. I don't have a canister filter btw still using the built in filter on the tank I bought. Cheers
  2. Just wondering if anyone here on the forum uses any of the small Fluval, Aqua One, Ista or other small CO2 kits that are getting around and if they are any good. Thinking of grabbing one down the track when it's time to flood the up and coming 'Monte Carlo' nano. Cheers.
  3. I wrote this on another forum back home that I used to belong to but figured it would also be useful for Aussie's as I've recently purchased a dual stage regulator and had it sent here to Australia. The systems they sell in the store really aren't very good to be honest, and once you've had a dual stage regulator you'll laugh at the single stage you used to have. With a dual stage regulator its extremely easy to set the desired PSI and never have to worry about it changing as the tank empty's. Also a dual stage regulator allows you to use the entire CO2 cylinder until it is completely empty, often giving you a few more days if not a week or two over a single stage regulator. Okay so a lot of us use eBay and recommend it to fellow hobbyists and beginners coming into the planted tank world as a place to purchase their CO2 regulator for a "steal" but many of us get too intimated upon our first search because we have no idea what the heck the different model numbers mean and if it's right for our use or not. I get a ton of questions from people looking to switch over to a real CO2 set up from DIY , paintball, or just simply a single stage regulator, so I figured writing this out may help everyone involved. Lets start from the beginning; it's rare you're ever going to find a high purity dual stage regulator that already has CGA 320 fittings on it, 9/10 regulator's I've purchased from eBay have CGA 580 fittings which need to be changed out for CGA 320 fittings for north american use; however in Australia I know you use a different fitting "AS2473 Type 30" so this would need to be purchased. One thing to understand is that most regulator's are only made by a select few companies; it's cheaper for some companies to simply purchase a regulator from another established company and re-brand it as their own. Ex. Praxair, Prostar, and Restek regulator's are re-branded Concoa regulators, this makes it MUCH easier to search for them online as they will all use the same model number format. After purchasing numerous Concoa regulator's I've been able to figure out the coding/model numbers so hopefully this will help you while searching. Understanding Model Numbers - Concoa, Praxair, Prostar, Restek The first three numbers will ALWAYS represent the actual model of the regulator you're working with. As an example here is a Concoa regulator I recently purchased, lets break down the numbers : 3123332-68-B03 The 312 lets us know this is a Concoa 312 model, the next series of numbers "3332" will tell us the outlet pressure, inlet pressure, gauges chosen, and any other features the regulator may come with. Anything after those numbers like the "68-B03" is generally irrelevant because these are usually the smaller things like colour of the regulator knob or other things that don't concern us. The only numbers you should be concerned with are the first set of numbers I outlined before "3123332" Outlet Pressure 1: 0-15 psig 2: 0-50 psig 3: 0-100 psig 4: 0-250 psig 7: 0-150 psig Outlet Gauge 1: 30"-0-30 psig 2: 30"-0-100 psig 3: 30"-0-200 psig 4: 0-400 psig 7: 30"-0-200 psig Inlet Gauge 0: None 3: 0-4000 psig 5: 0-1000 psig 6: 0-300 psig 7: 0-400 psig Outlet Assemblies 0: 1/4" FPT Port 1: 1/4" MPT 2: 1/4" Tube Fitting 3: Diaphragm Valve 1/4" Tube Fitting 4: Diaphragm Valve 1/4" MPT 5: Needle Valve 1/4" MPT 6: 1/8" Tube Fitting 7: 3/8" Tube Fitting 8: Diaphragm Valve 1/8" Tube Fitting 9: Diaphragm Valve 1/4" FPT Assembly/Gauges 0: Bare Body 1: Standard Assembly (psi/kPa Gauges) 2: Standard Assembly (bar/psi Gauges) After going through the different numbers we can read the code "3123332" as follows: "Concoa 312 Dual Stage High Purity Brass Chrome Plated Regulator- 0-100 psig outlet pressure, 30"-0-200 psig outlet gauge, 0-4000 psig inlet gauge, diaphragm valve 1/4" tube fitting outlet assembly, standard assembly bar/psi gauges." This will also work for other model numbers like the 212- I also have a 2123331 which is also "Concoa 212 Dual Stage High Purity Brass Chrome Plated Regulator- 0-100 psig outlet pressure, 30"-0-200 psig outlet gauge, 0-4000 psig inlet gauge, diaphragm valve 1/4" tube fitting outlet assembly, standard assembly bar/kpa gauges" the only different was the bar/psi vs bar/kpa. I hope this helps you in any way ! and if anyone has any questions feel free to ask and I will point you in the right direction
  4. First bottle in my aqua one nano co2 kit lasted maybe 3 weeks, not sure if thats normal but i did expect longer. Latest bottle not even 2 weeks and we are empty. At $35 a pop its in excess of $10 a week on co2. Can anyone tell me if this is normal? I want to upgrade the a refillable cylinder but the initial price is a bit much for me at the moment
  5. I got an Aqua one nano co2 a few weeks ago, seems im starting to run out of gas. The aqua one replacments are approx $34. Just wondering if this kit is compatable with painball cylinders at all or any other cheaper brands.
  6. hi looking into CO2 for my 200 liter Freshwater Aquarium, I am on a budget, and live in Cairns FNQ-where we don't have Aquarium Shops, like in Brizzy Can someone enlighten me on what I would exactly need Would like to have CO2 on a timer Thanks
  7. I’m looking at setting up CO2 on my tank (2.6x1x.75). I’ve got a few pcs of parts for it and I think I need a CO2 cylinder. I need suggestions on where to source CHEAP and good quality CO2, that can be refilled. Also estimated cost so I can reserve some money for it. I only have anubias on my tank and just have normal light. My intent is to help the anubias thrive. The tank has rays as well so not sure how the CO2 will impact the water parameters.
  8. Hey All, I've had heaps of troubles with achieving CO2 concentration within my 3x2x2 Tank. Using a drop checker I can get the correct concentration but the bubble counter is going to fast (7+ bps) to count and I go through a 2.6kg cylinder in a month or two which seems rather quick from my understanding of how long they should last. After going through 3 cylinders worth and because the tank wasnt at home I wasnt noticing it go empty for a week i decided it would be better to stop rather then the up/down of pH etc as the CO2 ran out every few weeks. I had been using a cheapie ISTA co2 reactor with the supplied line (which i suspect is silicone which could be a big part of the problem). As such I was going to completely overhaul the CO2 system looking at a new reactor and I couldn't decide between going for a Serra version of the ISTA style which I hear is good. The other option I noticed was the UP Aqua In-Line Atomiser and I was wondering how people had gone with it and how it compares to the Serra.
  9. Hi, What do you guys use for your Co2 setups. I have read people recommend the UP atomizer inline diffuser - https://www.google.com.au/search?q=up+atomizer+inline+diffuser&espv=2&biw=1396&bih=694&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjT3P3YlrLKAhVlPKYKHYZFC1AQ_AUICCgD&dpr=1.65 and others recommend a reactor - https://www.google.com.au/search?q=up+atomizer+inline+diffuser&espv=2&biw=1396&bih=694&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjT3P3YlrLKAhVlPKYKHYZFC1AQ_AUICCgD&dpr=1.65#tbm=isch&q=ista+turbo+co2+reactor+diffuser I will be using this for a medium-highly planted 4ft 300 litre tank. What would be the better option? Thanks
  10. hi i have just setup a co2 system in my planted tank. how much psi should my gauge read for a 300 liter aquarium?
  11. Hi, I am bout to setup Co2 for my 4ft 300 litre tank. Does anyone have any recommendations on what to get and brands to avoid etc? And with the Co2 bottles, why do people pay $300-400 for aqaurium brand bottles when you can get Co2 bottles from home brew shops for half the price? Am i missing something?
  12. Im going to try some diy co2 wondering if anyone else does this. Im just getting ideas.
  13. Hi. I was out and about today and heard an extraordinary claim at a LFS. Nothing unusual about that, but this one has peaked my curiosity. The claim went along the lines of a customer, with somewhat a background im biology, was setting up a new 1500L tank. To kick things along, they combined 473ml API CO2 Booster with double the amount of Quickstart. The result, observed under a microscope, was roughly a 3 fold increase in the bacteria population against just using Quickstart alone! Given that glut is not, for the most part, the most friendly of compounds, i'd been expending a result more akin to nuking a planet from orbit! But seemingly no. Has anyone heard of or come across similar information? I did a quick hunt but nothing immediately turned up. It would certainly be a very useful combination. Cheers.
  14. Hi. Does anyone possibly know if Aqua Medic CO2 regulators will fit Ista CO2 cylinders? I was looking at an Ista cylinder yesterday but it looks like the fitting may be a little small. Where the regulator meets the cylinder, the diameter looks to be 12mm on the regulator side. If there isn't a direct fit, does anyone know of an adapter or cleaver plumbing solution? Cheers.
  15. Hi all, running a 500g ista co2 kit and everyday im manually turning it on and off and tuning it (probably not to the exact same rate each day to be honest). Wondering whats the best option money wise to setup a solenoid on a timer with the lights (they seem to be expensive though) or have some sort of straight up on/off valve i can switch so i dont have to sit there for 10 minutes and tune it each morning?
  16. Hi all, I am playing with the thought of setting up a tank that has very low conductivity and PH. To ensure that the PH is kept around 5.5 i was thinking of using a CO2 system with PH controller. There is no plan to add plants to the tank and i was wondering if the CO2 in the water will be harmful for the fish as there would be very low oxygen. Using RO water i will try to keep the conductivity around 50mu/s adding only blackwater extract to the RO water. Usually the ph would be pretty unstable in such soft water and that is why i thought a CO2 PH controller might be the way to go. Maybe someone here has some suggestions on how to reach and maintain these water conditions. Looking forward to heaps of input :-) Thanks
  17. Given up on the tunze co2 reactor. Looking at trying the reactor in the link. Thoughts? Is anyone aware of any other options for in-tank, powered co2 reactors? I don't want to use in-line diffusers in case it ever leaked. The tunze reactor just can't keep up. If I push bubble count, then I get a death rattle. Otherwise perfectly suited to tank smaller than mine (150gal). Power Reactor | Power Reactor pg1 co2
  18. I recently bought a Dupla tank and co2 reg second hand and the reg keeps venting through the safety valve is this a common problem/any ideas who or where I could get it fixed? I have a feeling a seal is gone somewhere
  19. Hi Guys Is it feasible to run 2-single stage regulators in series to do what a 2 stage regulator does? The 2 single stage regulators I have,the 2 stage regulator I would have to purchase, is the reason that I am asking? Thanks
  20. Never seen this before, went to an apartment and the guy had a small tank set up with a massive chain sword growing in it. To my surprise he had a Fire extinguisher on the floor feeding Co2 to the tank through a valve then to a diffuser in the tank. The extinguisher was clearly labeled Co2 only. Can you get them re filled? Novel idea though. Cheers Squidman
  21. Hi all, I've recently upgraded a few things in my 2ft (20 US gal) planted tank to get it towards the "high tech" end of the spectrum. It's running 2x24W T5HO bulbs at 6500K and 10000K along with pressurized CO2 on a solenoid running at about 1.5bps (for the moment) and is filtered by an Eheim 2215 with an inline CO2 reactor. Prior to adding the CO2 I was adding API CO2 booster (excel equivalent) and micro-nutrients, then gave Seachem's NPK a go, though dosing fairly conservatively and dealing with a lot of thread algae during that time. It currently houses 13 rummy-nose tetras, 2 black phantom tetras and 2 juvenile SAEs (smaller than the tetras) as well as 2 riffle shrimp and 15-25 Neocaridina shrimp at a guess. Moderately planted with Blyxa, dwarf hairgrass, a few crypts (wendtii, balanase, parva), Hygrophila difformis, stargrass, pygmy chain swords, and another stem plant species that I can't recall the name of. Since adding the CO2, growth has increased dramatically in the stem plants, but I am still battling with the algae. So much so that I had to severely cut back most of plants to remove the majority of the algae-infested leaves. Ideally I would like to use the Estimated Index for dosing but with Seachem's NPK that will become a money pit unto itself... and sourcing the dry ferts seems rather difficult here, especially KNO3. Regardless, my questions are more about the nutrient balance in a planted aquarium. Quite a few products that are sold as "complete" plant fertilisers specifically state that they are nitrogen and phosphate free, containing mostly potassium, magnesium, sulfur and calcium, and claim that sufficient N and P produced through feeding and fish waste. Is this likely to actually be the case in a high light system? My understanding is that ammonia is the primary driver for most algaes, at least in the spore stage and that plants are more likely to utilise N and P than algae, provided that other parameters are reasonably good for plant growth. Given the relatively high bioload, is it likely that the algae is benefiting from the immediate form of fish waste (ammonia) and then the plants will be struggling to find enough available N and P, hence I would need to supplement them directly with nitrogen? I haven't seen many obvious signs of deficiencies in the plants themselves, just an excess of algae on some leaves and an increase in green spot algae on the glass. Is that also a sign of there not being enough P in the system? If I dose according to Seachem's calculations and ideal nutrient levels I'll be using 100mL of each in under 2 months... but would providing less NPK than recommended contribute more available nutrients to the algae than the plants? Thanks for your feedback - I'm also interested in anyone else's experience with nutrient dosing and higher tech tanks... problems, solutions, stories, etc. Cheers, Piet
  22. I am looking at low dose CO2 on a planted tank . The 30 inch with a Fluval light In my other thread . I was wondering what warnings and or caveats do yo have ? I am looking at using off the shelf eqipment with little if any diy . I was wondering what brand bottle ? Where on the Northside to get the bottle filled ? Do you still need to freeze the bottle prior to taking it in . Last time I did this I had issues with my Red Sea bottle as most places refused to fill it( about 05) . I know that Dupla bottles appear to be universally accepted are ther ant others . What are you using ? How good is it ? Looking for advice thanks Ian PS. If somebody has a Dupla bottle still in test to sell I may be interested .PM me .
  23. Hi fish people Please move this thread if it's not in the right section. Anyway I have decided to add CO2 to my tank. Tank is a 3ft Aqua One Horizon 130 with a AquaClear 70 HOB filter running. It is currently low tech but i want to add medium light plants and add CO2 now. I already have a used CO2 Bottle. It is a CO2PRO 0.82L bottle: http://www.aquascapedesign.com.au/products.php?product=CO2PRO-0.82L-%7B47%7D-540g-Alloy-Cylinder I have a budget of $200 and would like advice on which regulator/solenoid, bubble counter, diffuser, etc. to purchase? Specifically brand or models that you guys would recommend and which will fit into my budget. I have read that some people have purchased from this overseas ebay seller: goaqua88 on eBay Any CO2 equipment worth buying from that seller or can you recommend something locally? Thanks for an help.
  24. Dose anyone know where to get a O ring for a co2 reg both the plastic one and the tiny rubber one that goes between the cylinder adapter and the regulator nipple?
  25. Hi all got a ista co2 bottle and cant get it filled up ANYWAY cause its not aus aprroved and rang a approval place and they cant approve it either costs like 3500 lol. has any one got one of these filled up at all? otherwise i will have to buy my own larger bottle for about $290. i would have went that method first if i new the ista bottles werent refillable!! Ista 1 liter Professional CO2 Cylinder cheers
