SpidersWeb Posted July 4, 2007 Report Share Posted July 4, 2007 Not sure. But best way to get algae off the glass is to wipe it normally, just a clean cloth with no chemicals on it will do. Chemical treatments should be an absolute last resort, if that. Quote Link to comment Share on other sites More sharing options...
Ianab Posted July 4, 2007 Report Share Posted July 4, 2007 Copper sulphate (bluestone) can be used VERY dilute to kill algae, but it's also toxic to fish in slightly higher concentrations. Also it will only clear the algae out temporarily, once the copper is removed from the water it will just grow back. If it's a cold water tank, get a magnetic glass cleaner. If it's tropical, get a little bristlenose pleco Mechanical or biological control is much safer Cheers Ian Quote Link to comment Share on other sites More sharing options...
SpidersWeb Posted July 4, 2007 Report Share Posted July 4, 2007 Oh Copper Sulphate, yeah do not use that. If you do use it very diluted with citric acid. I would definately not go to this extreme for algae in an aquarium. Will kill fish sensitive to copper and snails (duh), and if dosed too high will kill everything. I had a very diluted mix I used to use to fight fungus, worked well, but I wouldn't use it in a community tank. Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted July 4, 2007 Report Share Posted July 4, 2007 Chelated copper sulphate has 4 to 1 citric acid added to it and it slows the absorbing of copper through the gills and therefore makes it less toxic for fish. Used to treat velvet and a number of other problems but can cause temporary sterility. I killed over 300 Nothobranchius guentheri (killies) almost instantly treating for velvet and I used 1/6 of the normal dose. It is the main ingredient in meds to control snails but is not used in aquariums for algae control that I am aware of. I would leave it in the jar.

livingart Posted July 4, 2007 Report Share Posted July 4, 2007 copper sulphate kills crustaceans in marine and freshwater systems will therefore kill some parasites used to kill fungus etc. on outdoor plants used it once never used it again Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted July 4, 2007 Report Share Posted July 4, 2007 It all depends on the concentration of course. Quote Link to comment Share on other sites More sharing options...
