I have a 55 gallon that used to be a community tank, then i decided to go with cichlids, I have a jewel,2 convicts, a yellow lab,jack dempsey,a parrot,a pacu,a red hook silver dollar,lepordinus(sp) and a 13in pleco.. I have 2- HOB marieland 350 filters, for at least a month now i have had cloudy water, I have tried everything, it seems like a product (acurel-f) works the best but its still not completely clear, I recently heard that it might be that my bubble strips, that run the length of my back wall maybe causing it, I heard that filters maybe suking the bubbles and chopping them into smaller bubbles which cannot float to the top causing the cloudyness? I have never heard of this, any suggestions? maybe on where I can move my bubble strips to? If i even need them, or anything? please help!!!
