thank you both for the advice. i had a sw
tank when i was younger(15 yrs ago). It was with an undergravel filter and no live rock. FOWLR
is new to me, but i have been reasarching for a couple months.
i have two powerheads allready but thanks for the aiming tip.
so i should TAKE OUT the bio wheel completely from the HOB
filter? in my reading I havent seen that anywhere. Logically that makes sense to me that it would impeed the filtration of the live rock, but i havent heard that anywhere.
thank you once again.
