I have an eshopps advanced sump which is 29 gallons and it has a compartment for a refugium which is 17.5 x 10 x 4 =3 gallons. I have it about half full of chaetomorpha. I have a 26 watt cfl plant bulb 6500k on it and the algae grows pretty fast. I took a little out the other day. How much of the algae should I be keeping in the refugium? Is half full adequate for nitrate removal? I have a little koralia 1 pump inside but that does not push much water at all. Do I need higher flow in the refugium?

I start with about half full. Let it fill up then take out about half and give it away. The growing algae uses up the nutrents, taking the algae out removes it from the system. When the growth gets too dense it slows down growing which slows down nutrent export.
