What's Your Lowest pH Swing?

[killer2001]

Managed to get only 0.07 differential between day / night on my pH! No reverse light refugium or anything. I do have a co2 scrubber and have been playing around with leaving windows open at night since the weather has been nice and cool here in Florida.

8.2's (high) to 7.9 (low) in a typical 24-hour period. No Co2 scrubber, but I do have an air exchange system in my house.

location is North Dakota so its bitterly cold here. House is buttoned up for the winter. CO2 scrubber running in recirculating configuration . I dose kalk and Soda ash. no issues with PH whatsoever

Surely someone out there can beat my 0.07! Typically I get about 0.2 difference day / night in a 24h period.

Not much of a swing if at all. But sitting at 7.9 constant isn't all that great either.

I'm just ecstatic if it's consistently above 8.2 without having to really do anything else...
