  1. I need some more salt, but I use it for one purpose - hatching/growing out brine shrimp. I'm getting a general consensus here that the Bunnings/Woolies pool salt will be a-ok for this? (AND, probably a-ok to use in my freshwater tank, if ever I feel the ich to do so). E: And I should probably get a hygrometer hydrometer OR a refractometer
  2. That was the tipping point for me too. I was just basically annoyed by them up until the point they caused my expensive pump to grind to a halt. From then on war was declared.
  3. I don't think I've ever heard of the sugar method. When I websearch it, this thread appears as one of the top results. What's the overview?
  4. Sorry for the necro bump. But this is important. Using the amounts specified in one of my previous posts, I can confirm that the MTS plague was eventually eliminated. It took a few months, but I saw not one living MTS for several months afterwards. I have since deconstructed the tank for an entirely unrelated reason, but for anyone finding this post while searching in frustration with these pests, the nuclear option of copper sulfate was wholly effective, despite taking time to complete. Also- the fish were healthy, and I don't keep any shrimp. I also didn't have any loaches in the tank, which might be more susceptible to copper.
  5. That would also suffocate the fish, I think. An update: The 0.2mg/mL solution has so far only seemed to anger the MTS. After a week there were still snails going about their business and perhaps at worst, slightly inconvenienced by the presence of copper. So I added another 20mL of the 1g/L solution. It so far hasn't appeared to bother the fish at all, and the remaining plants are anubias which would probably grow in fuming HCL. Another week or so later and there were still snails moving around like they normally would, presumably in pure defiance. If they had middle fingers, I'm sure they would have them extended on a full time basis. I've added another 20 mL to the tank now bringing it to a total of 96mL 0.096 * 1 g = 96mg, into 220L or 0.43mg/mL. I don't think I'll add more than that, but rather let this slow burn now for a few weeks. If that fails, then I suppose the tank now belongs the to snails forever. Hail our new overlords.
  6. Thanks Donny I'll take a combined approach. The relative error in measuring 1g precisely on my kitchen scale vs measuring 10g is significantly larger. So I'll take 10g CuSO4 and do a 1:10 dilution, therefore starting with the same 1g/L stock as per above, except with more precision. 4mL of that into 20,000mL will make a 0.2mg/L concentration of copper.
  7. Bit late to the party, but this guy has a great DIY project and there are heaps of similar projects all over youtube.
  8. I posted this a million years ago, but it has exactly what you appear to need.
  9. So THAT'S what happened. I hadn't considered the sugar part. About a year ago, my budding scientist toddler performed an experiment whereby he added about 200mL of orange juice to the smaller tank. I wasn't home at the time and by the following evening the tank had turned a milky white colour. One of my angels had already died at that point. I couldn't figure out why the tank had gone into a massive bloom like that, until watching through one of the security cameras that serendipitously happens to have some visibility of the tank. The other angel died due to a poor decision on my part, but that's another story. So anyway, the reason for this necro dive is that it appears to be the only search result with MTS and copper in it. This source says that 0.2mg/L is the target concentration to eliminate snails, and I'm ok with it being a slow burn, rather than trying to nuke them from orbit with a high dose. http://www.aquaticcommunity.com/snail/coppersnail.php I don't need a miligram scale, that's what serial dilutions are for, and copper sulfate is cheap. I plan to keep the dose in the safe zone for fish, since there are 2 in there but at the end of the day, this MTS thing will destroy my enthusiasm entirely if they're not eradicated - and that won't do the fish any good either. This is for a 200L tank, give or take. Has anyone else actually done the copper sulfate method, and were there any pearls of wisdom learned/pitfalls? I will even take the chance of nuking my biofilter, just to be sure they're fully removed.
  10. Howdy. Are you still looking for a home for your ghost knife?
  11. I'm still waiting for a reply - but I'll definitely enquire about using PayPal or somesuch. I'll also get in touch with a few water treatment places as well, because for sure they'd have some contacts that deal with this stuff.
  12. I sent them an email asking for prices to Australia for a cubic metre. Go hard, or go home, I suppose.
  13. This K1 is abomniably expensive, for mass produced plastic spokey wheels. Why are we paying such a premium for this stuff? 5 minutes on google and I found this: 100% Vrigin PE Mbbr filter media, Mbbr media, K1 media, K3 media, View floating bio filter media, zy Product Details from Pingxiang Zhongying Packing Co., Ltd. on Alibaba.com They are selling it by the cubic metre. That's 1000L for ~$US 250-300.
  14. I have a *much* lazier way of dealing with sump levels: float switches that control power to the pump via a simple relay circuit. There are 2 of them in series, so that if either goes open circuit, the pump power is cut. That means that if the overflow stops working (blockage, siphon failure etc) then the upper level float switch trips once the water level gets too high. The second float switch is in the sump itself, and trips if the water level is too low.
