Lance's 225 gal tank

[Lance]

I've been trying to lower the nutrient levels in this tank for months now. Ever since last summer the SPS have not been doing so well. (lost a couple of colonies, and while some are doing ok, most are just sort of existing without really growing much). Softies and LPS grow like weeds of course.
I have a nice large growth of chaeto which I prune monthly, change 10% of the water weekly, (expensive!), and have tried vodka dosing and nitrate sponges. With this regimen I still could not get the nitrates under 10, (usually at 15 to 20). I could cut back on the feeding a little but I like my fish to be fat & healthy. I'm now trying the N-P Reducing Pellets. After 5 days I'm definitely seeing an increase in skimmate and the water is slightly clearer. A small outbreak of Cyano I had is disappearing as well. Very promising so far.
