I've been lurking for about 6 weeks now - have had the 30 gal. (high) tank up and running with 15 lbs. lr, some snails, hermits and a tomatoe clown (the clown was added about two weeks ago). Ammonia and nitrite have consistently been zero. I'm running a Penguin 330 with bio wheels. I believe that I should be adding a powerhead and want some advice - is one sufficient for this size tank or should I get at least two and, if so, should I put them opposing each other. I'm concerned that stuff is settling on the bottom (not a lot), but think the powerhead would aid in the filtration process. Thank you.
