  1. Hi guys, Finally relatively happy with this recent scape so time to share some pics It is the first time using Amano's 2:3 hardscape ratio and imo worked out pretty well. Also creating a lot of depth in this tank has been quite successful too. Some specs: Dimensions: 3ft x 38cm x 38cm Filtration: 450L/H power filter Lighting: natural sunlight Heating: nil Substrate: Aggregate Sand & natural river sand Hardscape: Large & small river rocks, goldvine driftwood Flora: -Microsorum pteropus 'philippine' -Microsorum pteropus 'windelov' -Microsorum pteropus 'needle leaf' -Vesicularia montagnei (christmas moss) -Anubias nana -Anubias barteri var. nana -Vallisneria nana -Anubias afzelli -Hemianthus micranthemoides -Ludwigia repens -Ludwigia arcuata repens -Taxiphyllum sp. (peacock moss) -Bolbitis heudelotii -Subwassertang -Crypt wenditti 'green' Fauna: -Leopard endlers -'Wild' endlers -3 x M. parkisoni rainbowfish -2 x M. splendida inornata 'Flat Rock Creek' -4 x Hypseleotris compressa Some fishy pics Enjoy, John
  2. Hey guys so I'm turning a calcium reactor (came with my co2 cylinder) in to a fluid bed filter for a tank I'm setting up for shrimp breeding, ill eventually add a chiller to the system as well:ballchain:. Just seeing what sand people would recommend to use in a fbf. I'm thinking pool filter sand but there is few types so I thought I'd see what people use and like. The first filter will be made from the main reactor and ill be blanking off the holes I don't need and ill put some corse filter foam At the bottom to keep the sand running in to the base. Ill be running the water though a little (11/12 L/min) iwaki magnetic pump. It crossed my mind to not use sand and use k1 or something similar, if someone with more experience with fbf wants to chime in and give some hints and advise that would be great.
  3. Hey Guys, Setting up a new marine Tank and thinking of trying Deep Sand Bed. Looking around on the net and there seems to be a lot of mixed opinions, just wanna see what some ppl's thoughts area Tank Measurements Length: 89cm Width: 33.5cm Depth: 58cm Sump Measurements Length: 61cm Width: 30.5cm Depth: 45cm Thinking maybe a 4inch deep bed in tank. Cheers
  4. Finally arrived - and ready to go for those that have been waiting - we received 1500 liters of it and a third of it has gone out today. Here is the link - be quick Bio Media
  5. I had this info posted on another forum a couple of years ago but I've been getting a few PM's about FSB filters here recently so I thought I would do a copy + paste here too. Fluidised bed filters can handle huge amounts of bio-load because they culture beneficial bacteria at a young active growth stage. They can maintain young bacteria cultures because fluid bed filters are constantly moving which causes the filter media to rub and clean against itself. This scours off existing bacteria, especially the mature inefficient bacteria. However sand granules are irregular shaped so there is always some beneficial bacteria retained and it is constantly trying to re-colonise all the new exposed surfaces. It's this new young re-growth bacteria that is the most active and effective for biological filtration. If you have trickle filters or sumps, you will already know about all the mulm buildup from the dead bacteria. This coats the trickle media reducing its effectiveness, lowering gaseous exchange + nutrients available to beneficial bacteria and greatly increases filter maintenance. The other big benefit of a fluid bed filter (for me at least) is these filters do not do any mechanical filtration whatsoever so there is never any cleaning to be done. Even the smallest particle of dirt will work its way through the FSB filter eventually. Fluid bed filters will handle large sudden bio-loads due to the dynamic nature of its bacterial culture and consequently are one of the fastest filters to recover from an outage. This is good for me as I am constantly adding large fish and/or large numbers of young fish between systems from one week to the next. As I wanted extra emergency filtration, this type of filter was the obvious choice for me. I run this as supplemental biological filtration because its a cheap effective safeguard. Rather than go into all the ins and outs of fluid bed filters Vs other types of filtration, I will start straight onto my build. There is plenty of technical information online about fluid bed filters for those unfamiliar with them or please feel free to ask questions as I go. This example is a fluid sand bed filter but there are other types of fluid filters too. Obviously not all filtration types are equal so you need to custom filtration to your situation. I'd prefer to answer questions than re-hash common knowledge to people. The only thing I would stress is a fluid bed filter should be regarded as a supplemental filter when starting it off. Young active bacteria are also the most oxygen demanding too so you may need to incorporate some re-gassing safeguards if returning filtered water straight back to your fish. The other important aspect for me is the cost of filtration. Although I have a lot of tanks, I try to reduce setup and operational costs. Luckily you don't need to spend a lot to get good results if you know what objectives you are trying to meet. I found these 45 L bucket/bins as a clearance item for only $10 each. As I was making 5 of these filters, the cost saving was beneficial. Almost any container will do but these were good volume, tall & narrow, cylindrical and slightly conical towards the bottom. Most people prefer to use glass or acrylic tube (or PVC pipe with a clear viewing window) as a filter chamber so they can monitor the fluidisation. Its very hypnotic! However, since I am on a shoestring budget and I would be monitoring these filters from above anyway, I decided not to worry about side views. I opted for open top filter over a sealed unit for ease of access and reduced costs so it was important the water level in my filter be above the water level of the fishtank. Comments are above each photo: A quick visual measure to mark where I would be drilling. The line is the top level of my tank so all holes needed to be above this. Only two holes needed for an entry and exit. Note that the exit drain hole (left) is lower than my entry hole. Important for power outages. I used a 32mm circular holesaw to accept 25mm PVC pipe fittings. I used standard 25mm PVC joins and a rubber washer as bulkhead/tank fittings. There isn't much pressure since its an open top filter. Because the bucket was a little too wide to keep all the sand in constant motion, I decided to add a bell onto the bottom of my input 25mm pipe. This was a 2L plastic bottle to spread the area of sand stirred up. Sand is so cheap that you don't actually need all of the media to be used but I wanted to eliminate potential dead spots as I am not going to be cleaning these filters ever. Actually I really wanted to use a glass bottle for a bell but I couldn't find a glass bottle wide enough in my shed. I heated the pipe for a snug fit onto the plastic bottle then cut off the bottom and removed the label. The practically finished product below. Just needs sand added next to finish off. There is not much to it which is appealing to me. Simple designs have less to fail and economical to build. The drain hole is the small T piece near bottom of this picture. I used a sideways T on inside as a safeguard against clogging. The bottom part of this T is the main drain path and the top acts as a breather and emergency overflow if the bottom ever clogs. IMPORTANT to make sure the emergency overflow is below the lip of your bucket!! I have enough experience to know one 25mm drain hole would be sufficient for the water flow I will be using. If your unsure, feel free to add a secondary emergency drain slightly higher up again or enlarge the main drain hole. The input pipe now has the spreader bell (plastic bottle) installed at the bottom to help stir sand. Because I am using sand as my filter media, I wanted to ensure none would escape from the filter into my pump tank by back siphon because sand and pumps do not mix very well. You could take some precautionary measures like raising your pump off the floor or adding a sand trap but instead, I have safeguarded against a back siphon (during power outages) by adding a breather tube onto my input pipe. Its the really tall central pipe. I could have used an check valve to do this but simplicity is my mantra. The breather tube does not need to be this tall but this was the test version. None of the pipes are glued since there isn't much pressure involved. This is my filter just filled and running. I had it on maximum flow to make sure the emergency overflow could cope so thats why water is draining down the top branch of T drain. I backed this flow rate down later as the sand was stirring well even at half speed. Yes I was too lazy to wash the sand but I know it will self clean in a few hours. Its on a fairly large system and the influx of some dirty water/sand may trigger some spawns. This is a side photo of it running in test mode. There is a 1200LPH powerhead (20 watts) running this unit. It has 25Kg of sand on a 12,000L system. The sand filter will be able to handle over 30kg of fish by itself when it is fully active. I could post a video of the sand fluidising but youtube is full of similar items. After a few days of testing, I did shortened the breather tube and place the filter right under the stand out of the way. There is no maintenance required so it could be tucked away. This filter currently maintaining 60 tanks - 3' x 2' x 15" and the other similar sized filters on larger systems. Thanks for reading Winston
  6. Hi guy's. Can anyone tell me if I would have enough water pressure coming out of a canister filter, (2200lph) to run a fluidized bed filter after return from canister to tank. If I can't is there anyway I can run an external pump before or after the canister to increase pressure. Or would I maybe be able to turn off the canister pump and use an inline external pump in situ of the canister pump motor to increase flow and pressure. Can anyone also tell me how effective UV sterilization units are. I was also thinking of adding one of these into my filtration system.
  7. Now this may seem like normal question to some but im getting a little lost in our world of fish. I need to know how many LPH your pump does that runs your fluidized bed filter. One company says up to 2000lph and another one says up to 600lph, with the second one being what i consider to be the better of the two. Im currently running a 1500 lph pump on this and it can hold 1.5L of media. Does the medai effect what flow rate i should have? Anyone that can shed somelight on this would be a BIG help right now. Thanks Al

  9. From this article on the web: Stunning Aquarium Bed Redefines Sleeping With the Fishes Forget about the race car or canopy bed you dreamed about as a child. This custom-made aquarium headboard makes your boring old Serta setup just about the most amazing place you can rest your head at night. And possibly the most distracting. The 650-gallon tank spans the top of the bed, and rests on a pair of matching tables on either side. The folks at Acrylic Tank Manufacturers, who created this masterpiece, have cleverly integrated a set of bedside lamps into the tank itself. But for $11,500, let's hope there's some way to completely darken the tank. Otherwise you could be wide awake all night finding Nemo right in your face. I'd be more concerned with figuring out how to easily feed the fish and do water changes!
  10. Hi All, My much loved Brazillie male is in a bad way. Found him doing a tail stand. Its as if his tail does not work anymore. He is also gasping for air. Checked tank levels and all are ok. Other fish seem to be all good. Me and a mate saved him and lots of his brothers ans sisters as fry from a LFS. He is around a foot long and has the best personality. Would love some help or ideas if anyone can help. Cheers Just had to share
  11. Hi all- i have an otto fluid bed filter but i need the rubber seal/o ring. I've tried heaps of different seals but none work 100%. If anyone knows where to get these from i would love to know- any help is appreciated. Cheers
  12. Just saw a moving bed filter as a sump.Would there be a problem in modifying my 4x2x2 sump to include one. I am thinking that I run in through a filter sock then into the moving bed then through the rest of the sump as it sits. Any problems or is it a waste of time and money??
