sumergold Posted May 14, 2009 Report Share Posted May 14, 2009 I've been having a lot of problems with thread algae, so I did some research. I read that hydrogen peroxide will get rid of it. On Sat, May 9 I put 2ml(per gal of water in a 10 gal tank - 20ml of HP altogether) in a tank using a syringe and squirting it where the worst parts were. Thirty min later I did a 50% water change. There were Endlers, both adults and fry in the tank and they are all fine. I tried the same thing in 2 more tanks, both with fish, with no observable damage to the fish. Now, almost a week later, I do not see any thread algae where a week ago, I could hardly see the floor of the tank for all the green. All plants and fish are fine and the tanks look great.

firestorm Posted May 15, 2009 Report Share Posted May 15, 2009 Peroxide can be used to get rid of it, though only use small amounts. Hydrogen peroxide can decrease your pH being it's acidic, so using too much can harm your fish. When I use it I only squirt some on the bad parts, or you can do a dip with part water and part peroxide with your plants, it has less chance of melting them than excel.

werner Posted May 15, 2009 Report Share Posted May 15, 2009 Yeah, go easy with the peroxide- it can easily harm the fishes' gills as well. Effects will vary from tank to tank, so there's no "safe" concentration. Quote Link to comment Share on other sites More sharing options...
Wingin' It Posted May 15, 2009 Report Share Posted May 15, 2009 Question for ya Werner &/or Firestorm... I have a small piece of driftwood with Riccia on it that has developed a crazy growth of this thread algae...If I were to put the whole thing in a bucket and try this squirting of HP on it and then rinced it with old aquarium water at water change time...would it be ok? Melt the riccia or anything? remnants of the HP on the plant that would harm my bettas? Quote Link to comment Share on other sites More sharing options...
werner Posted May 15, 2009 Report Share Posted May 15, 2009 Dunno if the peroxide would harm riccia or not- you'd have to do a test. Otherwise, rinsing it before placing it back in the tank should be fine. Quote Link to comment Share on other sites More sharing options...
aiki-guy Posted May 15, 2009 Report Share Posted May 15, 2009 I'd be careful with the riccia; my friend tried spot dosing his riccia with excel and managed to melt it all away. I know vals are sensitive to spot dosing with both excel and HP (same effect - both chemicals melt them away), so you might be in the same both with your riccia.

Riccia was one of the plants that I had that had heaps of algae on it. I had used a syringe with hydrogen peroxide in it to spot treat the plant in the tank and it is ok a week later. I also had a piece of driftwood that had lots of algae, so I removed it and placed it in a 30% solution, then rinsed it in a pail of old tank water and the jave moss it still ok.

firestorm Posted May 16, 2009 Report Share Posted May 16, 2009 I don't think the peroxide reacts the same way as excel does. You should be safe to dose them with the peroxide. That reminds me, I should squirt some on the wallichii Quote Link to comment Share on other sites More sharing options...
