I realized on friday that when I woke up my discus were all breathing on top of the water, frantically I checked in my wet dry to see the temp and out of the corner of my eye I see a AA battery with the top corroded and residue......... By Sunday all 6 of my beautiful discus died. Don't ask me how the battery ended up in there, but my question is, how many water changes must I do to ensure I got all the battery acid out of my water so that I can try and buy new fish? I've already done 3 complete water changes........ Anyone have any advice for a very sad aquarist?
