I need some expert advice please. We have a 90 gl tank which has been set up for several years as a FOWLR which was healthy, but not beautiful. I have a 30 gallon sump/refug with a Coralife skimmer rated for 125 gallons. I just took over the reins on this tank from the husband and hope to turn it into a reef tank. I have been reading as much as I can get my eyeballs on but have several questions that I hope to get answers to.
I need to find out how to control nitrates in the tank.We have 100lbs of LR and about 30 lbs of LS as well as sand in the refug. I have a handful of chaeto in the refug as well. How do I get my hands on more and what types do you experienced reefers use? I do H2O changes but don't really notice an appreciable drop in nitrates which needs to happen because I want to have coral and anemones. Levels stay right around 10-20 ppm. Is it really possible to get your nitrate level to 0?
