I'm actually fine right now, my pH is in the 8.0-8.2 range. Two days ago I measured my alkalinity (Elos test kit) and I was sitting at 10dkh. Like I was saying, in the winter my house is too closed up and I have a lot of CO2 build up which drives down my tanks pH. In the summer I open up the downstairs windows and everything is fine. I dont think many of those guys on the Reef Central TOTM live up in the frozen north like I do. Many of their tanks are running chillers while my heater is still kicking on each day.

I run an old down flow PM 622 Calcium Reactor with course ARM media and a DIY 6" diameter 1' tall effluent chamber with fine ARM media. pH in the reactor is between 6.5-6.6 and controlled by an AquaController. There is enough flow through to maintain my tanks calcium and alkalinity at constant rates of ~420ppm and 11dkh respectively. I also run all of my top off (about 2 gal a day) through a knock off of a PM Kalk Reactor.

Do you see anything that I could do differently with regards to my reactor?
