DIY Calcium Reactor
I was looking into couple of commercial calcium reactors but then later decided to go with DIY one. It saves me around 100 bucks and gives me a nice size calcium reactor. After a week in service it raises my KH level from 8 dKH to 11 dKH which really makes me happy already. I fill it with 16 lbs of A.R.M reactor media but still find out that it’s not enough. It would at least contain 20 lbs. The reactor is powered by Mag-Drive 5 Utility pump
I also bought 15 pound CO2 cylinder for the reactor and I know it’s gonna last at least a year. To control CO2 injection rate, I decided to get Milwakee MA975 CO2 regulator despite the fact that so many have problem with it controlling bubble rate. I guess it’s because the operating pressure is set too low. I set mine at about 20 psi.
