So my tank (90ish gallons, total volume) is a little over 2 weeks old. It cycled it in a few days using Brightwell's Microbacter Start XLM. Last week ammonia and nitrate was 0, nitrate at 2 (using Red Sea test kit) and phosphates were at .104ppm (Hanna phosphorous checker). I added some chaeto last Wednesday (1/22) which has been growing rapidly. I tested my water today and my ammonia, nitrite is at 0, nitrate is either 0 or close to undetectable and phosphates are down to .04ppm. I currently only have 3 fish and am adding a relatively small CUC this Friday (1/31). I believe my phosphates are within a good range and I may cut down the photoperiod on my refugium to let my nitrates go up a bit. I am running carbon to keep water clear and a UV sterilizer 24/7 since last week. Should I wait to do a water change?
