Hello everyone! Any help will be much appreciated. My 75 gallon tank has been setup for about 6 months. Was using a fluval 305 with emperor 400 hob
filter. Everything has been great with water except the nitrates have been between 40 & 60. Just added a 29 gallon refugium setup a week ago to replace my fluval 305 canister and emperor. Using live rock and chaeto along with a uv
sterilizer and protein skimmer. Both the refugium & fluval have been running right now how long before I can shut down the canister filter and just use the refugium? Just checked water today everything seems good except nitrates but they are coming down. Should I run both or just the fuge?
