i am new to this hobby. i have a 30 gal long that is in the nitrite stage of cycle, it is taking forever. i have a fluval canister filter packed with carbon biomax and clearmax. i also have a bio wheel 200 that i have left on just for extra support as the fluval is a 105 and only moves 90 gal an hour. is this sufficient or is a sump system really need i do plan on adding a protien skimmer, when i find one that is not made to run a 100 gal. any help on that would be appreciated. i am still waiting on my light shipment was delayed a week due to hurricane irene. it is a deep blue solarextreme, 36" 4 bulb. i have limited space also the tank is not drilled for a sump. one last question what is the current system capable of supporting.
