Is ick alway's in your tank. I was told that fish live with ick at all times. It just affects the fish when it's stressed. I have had two tanks crash from ick.first time a powder blue tang and the second time it was a powder brown tang.I used kick ick and it didnt work. Now my naso tang has ick . This time I took the NT out and put him in the QT tank and I put kick ick in.This time I can save some money .Kick ick is 31.00 a bottle ,Tring to treat a 210 is $$$$$.I also feed garlic with my food and I have a 30 watt uv. I must have the worst luck when it comes to ick.
