CO2 bubble per minute

[kj5432]

I'm trying to get an idea on the amount of bubbles per minute that people dial in their calcium reactors. How many bubbles per minutes do you set your calcium reactors for???

60 seems like a good start, you need a ph controller or pen to measure the ph of the exhaust. I keep my ph at 6.6. It really also depends on the how much ca your tank needs size amount of stonys etc. DSB. Try exhausting it near or in your skimmer to blow off excess co2, or put it in a box with a airstone in the sump. Ca reactors really lower ph.
