Ive had my 37 gallon, drilled with 15 gallon sump up for coming up on 4 months now. This past month ive been batteling cyano, really bad! Its covered the front portion of my sand bed, only the sand where theres light. Also now most my live rock is being completly covered by it. My tank specs are as follows:

37 gallon drilled
15 gallon sump
in the sump have chatamorpha algae growing
Aqua C remora protein skimmer
Ammonia 0
Nitrite 0
Nitrate .5ppm
Phosphates show up at 0 but who knows from all the cyano
salinity 1.025
ph 8.0

Ive tried increasing current where the cyano is appearing, but that didnt work. I though my old skimmer wasnt doing good job so bought an Aqua C remora which is actually pulling alot more. Any ideas on what to do? Dont want to treat with chemicals than i will just get a greater strain of cyano. I just ordered a live sand, mini stars, and worm kit from IPSF.com
