Ok, I know Goldfish require double the filteration due to their massive ways.. I'm probably at bare min, but, I got 320 GPH runnin' thru a 29 Gallon. (Aqueon 30 Whisper 200gph, Aqua tech 10-20 120gph)
I have one large adult fancy goldifsh and about to add a black moor adult after hes thru his quanitine stage.. Think im at the bar or I need more?
