Who is Using a Refugium for Nutrient Control?

[mark]

I have a 145g display and a 75g sump, to which I've added a 20g primarily Chaeto refugium.

Before the dedicated fuge always had zero or near zero NO3 and really no algae problems but did have a small area just between the baffles for Chaeto, so really can't say the dedicated 20g made a differance with nutrients.

I run a fuge with chaeto on a reverse light cycle. You know it's doing something because the macro is growing and taking up nutrients as it does so. A side benefit is that chaeto and other macroalgaes encourage a larger pod population by giving them a great place to reproduce.
