Speaking of help. i need it. I have a 26 gallon tank. I have a tetratec living filter PF150. I have had my tank for the 4th week this week. i have tested the water almost daily and all leveels are fine with t bit of hardness noted. Included in my tank are 4 neaons, a chinese algae eater, a plet, a betta fish, two swordtails and a molly and two small danios. The problem I am having is that I dont think the filter is giving them enough air. I have a airstone but have lost about 5 fish so far. I see white fuzzy stuff on my swordtail and the one bleeing heart tetra that dies had white stuff o nhim also. Beleiving it was ick I treated the entire tank this is the second day but I jsut lost another Angelfish today. Any notes of wisdom? I am thinking of getting another filter I am not so sure the living filter is doing its duty.
