I thought I had a problem with cloudy water from dirty water but not I think it might be from something else. I have tried a HOB filter, internal filter and now a canister filter with a UV light and the water still appears cloudy. This morning I looked at it closely and there are millions of tiny bubbles from the filter which I believe are making the water appear cloudy. Is there anything I can do about this or am I stuck with it? The aquarium in the fish store with the same type of filter is crystal clear. I did just install the canister filter last night so maybe I need to give it more time but I do see millions of small bubbles which seem to catch the light and make the water seem cloudy.
