Hey I have 72 bow, 265watt CF, c02 injection/bubble ladder, just ordered dry ferts/regular flourish for trace, a dose of excel every day so far with injection but might cut it down to 1-2 times a week maybe just one dose of excel at beginning of week or something... anyways... I got magnum 350 and want to fill tank up to the top so very little surface movement... I bought air pump the other day like an air pod for 55 gallon thought it would be fine... should I run it during day or just at night? and... where should I put air stone? torwards ground under output? maybe try to get air bubbles pushed by output torwards top of tank? or something? does it matter?
