Hello. I have a 10 gallon. There are 3 guppies, 1 platy, and 2 snails. I realize (now that it's too late) that this is way too much of a biological load for a new filter. And so, I need some advice on how I should go about doing this.. I am using an aqua clear 20 HOB filter. I tested my water after doing a water change and ammonia is what I think to be 2ppm. I know it's a little high- the fish, however, seem to be doing fine. The Ph reading is 7.4. Looking for any advice on how I can cycle this tank with as little stress to the fish as possible. Thanks in advance!
