My pH has always been 7.9 to 8.1 or so. I bought a Kalk stirrer to offset the added CO2 coming from my calcium reactor to see if I could bump it up a tad. I've been going slow, increasing the amount dosed (via APEX DOS) every few days.
I began with the recommended 150 grams of calcium hydroxide and have dosed about 5 gallons by now. The color of the solution remains roughly the same. Fairly clear at the top, and milkier below with a 1/4 inch or so of undissolved particulate on the bottom.
How do you know when it is time to add more calcium hydroxide? How do you know how much to add? Do I just dump it out and mix new?
The volume of the stirrer is about 6.5 gallons. Reef Octo 250.
Perhaps this thread belongs in the Equipment forum but thought I would start here. Thanks.
