Hi - How quickly things change...Two months ago I purchased a 15g setup. A couple of weeks later a friend of a friend was moving and gave us their 29g tank with sand substrate, plants, and fish. I moved the fish and plants from my 15g into the 29g as we really have only one good location for a tank right now. The tank has been up and running at my house for a month and a half. It is fully cycled, am is 0, nitrite is 0, and nitrates are ~10ppm.
There are currently two AC
30s running in either corner with 3 filter tube extensions.
My questions -
1) I have "particles" floating around the top 1/2 of the tank. The lower 1/2 is clean of free floating debris and looks good. I added filter floss to the two AC
's and it has not gotten much better. Should I eliminate one or two of the filter tubes to raise the intake? Any other ideas?
2) I want to upgrade to a canister filter. I have decided on Eheim. Since Eheim's seem to run forever I want to buy a larger filter to account for any future increases in tank size. Would a 2217 be overkill on my 29g?
