Hi

I im going to have an open top tank and was wondering if dust might be an issue, considering how much dust get caught on fan blades will enough dust on the tanks surface be a problem??

thnx for input.

argg i see, so 1100 g/ph for CL and 950 g/ph for return should be good enough for a 90gal? or i was going to add 2 seio M620's at 630g/ph each if i needed to.? what do u think?
