I've put a brand new small aquaball in my 55 gal for my 12 gal. How long do u think it will take to cycle?
A while id imagine, the ammount of ammonia present in the 55 will be minimal due to the bacteria in your main filter utilizing itId give it a good month of use to be sure.
How are you finding the aquaball? Ive got the smallest model in the 20 as a powerhead and I quite like itthe venturi feature is nice too.

Id imagine bio-balls would be okas i said mines only a powerhead so i only use the original sponge and blast it clean every now and then
Venturi feature, its the snorkle that pulls in air from the surface and shoots it accross your tank
