Try use rowa reduce the phosphate level. Your pellet output should go straight within skimmer intake area. Lighting period ? Is this a new tank with new biopellet?
Been to spotlight and bras basah chasing after this plastic canvas. They don't have it in stock. Anywhere else available or I can order it online? Heard some reefer bought it in sheet sizes a4 and such but all I come across are those smaller than palm shapes.
Some let it run off with Di till no more brown before placing into sump.. I place in a container ,rinse it with roDi couple rounds then pour the clearer mix into fr.
I thnk it depends on your coral placement and height from your water level. Can slowly acclimatize them rather than setting all 100%... Some other forums also has reefers recommending not to set till 100%
