Were you referring to me?
Honestly,not really.I just do weekly 10% waterchanges a week.I do dose Iodine(Lots of softies means rapid iodine depletion).My system is very simple
rotein skimmer,powerheads,and canister(cleaned weekly).Lights are JBJ 4x65w PC's.
Oh and my trates are always near 10ppm.I feed phylaplanton(sp?),and cyclopeeze.oyster egg(mainly for the Gonio).I'm no expert but I think my coral benefits from having slight nutrients in the water.
Here's my tank from one year earlier,you can see how they have grown.
