Well, don't eat your fish now!Originally Posted by wh33t
Yes. With that many fish I would try to change as much water as you can. Maybe 90% daily??? Also, don't feed them! The thing is they will produce a ton of ammonia if you do! I know they're really small fish; so, they should be okay. Honestly, if they can survive the chlorine level of your tap water, I would just use plain tap water as the treatment doing 90% water changes daily. Chlorine kills all that same stuff listed there, but it can be lethal to the fish if the levels are too high. This concept is the same as treating with salt. The chloride ions are what are doing the work, but also what are dangerous to some fish (not tilapia, they have a chloride cell).Originally Posted by http://www.petsmart.com/product/index.jsp?productId=11147154
