Okay, I can understand that in some reefs nutrient buildup would be a real problem, especially if there is no natural means of export, such as a refugium or macroalgae in the display tank. MA, like house plants, plants in a planted FW tank, etc., need P,N,K for proper growth. P = phosphate, N = nitrogen, K = potassium. I'm thinking that if a tank has macroalgae somewhere in the system, nutrient buildup shouldn't be that much of a problem, even for phosphate which MA would certainly use.

Just a thought, anyway.....
