Ok I ant seem to find the answers I'm needing so I thought I would post and hopefully learn what I needy know! Some please tell me everything I should buy from powerheads, lights, pumps (all the specifications on each item) to get my tank going! I have a 55 gal tank with 20 gal sump so tell me what I need to buy lol! I'm not sure about how much I should be pumping and how big of power heads I'm needing, what else am I missing! HELP!!! Thanks
