Thanks Don. I'm running the tank between 73-74 now. I will slowly bring it up to 76 by summer, and back down to 73 by winter next year.
I haven't noticed any decrease in nitrates or phosphates on test kits, but I have noticed a decrease in nuisance algae both in this tank and the fuge. I also decreased my daily water change amount a little bit. I'm still adding more biopellets, need to order more. I bet for my system I could run 2-3L of pellets and still have plenty of nutrients for my seagrasses to grow with. Right now I'm only at 1L.
