Help me get it up! Seriously.... it's 7.57 right now. Been running my fuge light 24/7. My Calcium Reactor is single chamber and internal pH is kept at around 6.8 with a steady flow of effluent. I could probably manage to get a line of fresh air run to the sump but it's going to take some work. Could also add a second chamber to the CaRx. I don't want to do either unless I know it would make a substantial difference. Any other suggestions?
