We've been having a huge problem with ich in our tank. it successfully killed off all of our original inhabitants a couple weeks ago, and even after a complete disinfectant spree, it has returned with our new fish. The first treatment we used was rid ich and it was horrible and didnt even slow it down. Now we are using Mardel Maricide in combination with aquarium salt, no light (since we heard that the light actually helps the protazoa to spread after hatching), raising the temp of the water and vaccuming the gravel for eggs. It looked like we had a good hold on it a couple days ago, but this morning it looked really bad and our kissing gouramie's have tufts of with on the now too, just like my red tinfoil barb had before he passed. Please help me quick! My wife and I cant bear to see another fish go..........
