I'm fairly new to reefing and have a 30 month old mixed reef tank with some softies, a few LPS and a few SPS. I'm dosing BRS two part (soda ash and calcium chloride) along with magnesium with a Red Sea auto-dose which is working fine but I can't get pH above 7.9 to 8.0, even with a small chaeto fuge and a CO2 scrubber on the skimmer intake. I live in the midwest so opening windows is not an option for about 9 months a year. Tank is in the basement of a new house with 5 people, 2 cats and a dog. I can't run an outside air line due to the location of the tank. I'm wondering if switching from two-part to kalkwasser with the auto doser would be a good idea.
