I meant to ask, what would be a good stem/moss plant to place in the refugium that would suck up the nitrates/bad stuff quick? I use duckweed in the big tank (55gal)and pull out about a cups worth a week. As of yet (3 years)I have only had one algae issue (green hair)and that only lasted a week after i cut the lights back to 8 hours. The duckweed makes good garden fertilizer but I do not want duckweed in this tank.
Essentially i am looking for a plant that I could partially remove from the refugium on a weekly basis that would assist in keeping the parameters in check.
