I'll feed 15 cubes worth of coral and fish food until all the algae in the display is gone (which seems to be happening already.) I always thought I was feeding alot, but alot now has a new meaning. I'll increase feeding when algae is gone and STN/SDR stopps.
It seems better. Hopefully I'll get growth on the corals within a few weeks of the current feeding regime.
A question though, how can I grow so much algae when feeding so little and running skimmer and GAC at the same time, and still get algae in the display? There really had to be very very limited amounts of N & P in the system, even very limited food with the skimmer, GAC and scrubber at the same time.
