Filtration idea's??
 

OK, I am looking for ideas for my tank. I only have a 10g sump, and not much room left under the 45g tank for much else once I put the Top up water bucket in there. I have a small, 10"x10" section of my sump that I could put Chaeto or Rock rubble in, I have a Aqua C Urchin Skimmer in the sump, and filter sox on the tank drains. Would a PhosBan reactor be fine? Want Softies and LPS mainly. 2 clowns, Fire Goby, Bangaii Cardinal and Royal Gramma. Maybe one or 2 others. Have 24 Hermits in there now, 2 Clowns and a Cleaner shrimp, and keep getting Cyano. Thinking Im not filtering enough??

Basically, I need some idea;s. What works good, what works so-so. Would like to keep Bi-weekly water changes If I could too, or less. Weekly is just too much for my schedual of working 2 full time jobs
