ok on my 58 gallon i have 8 lemon tetras,5 black neon tetras, and 9 gymno quillero growouts 1.5". i have 2 ac110 on the tank right now but it seems like so much theres a million micr bubbles everywere and what not even if full all the way. my water is 0 amm., 0 nitrite, and 10ppm nitrates regularly with by weekly 25% wc. do you think one filter would suffice on this tank.
