A little update. Everything is doing fine add some corals and it's not enough to put up my calrx running but water change made everything in line. Haven't check nitrate and phosphate today but alk is sitting around 8.2-8.5dkh where I like it at. Also got my pax bellum going so will test nitrate and phosphate next week. i have a question, I have a 57w uv sterilizer but when I go into apex why is it only drawing 44w is that normal? I just replace the bulb so it's not the bulb.
