CO2 scrubber: nonsense?

[SharksandTarpon]

Now that I have a controller, here’s what I have seen over the past week.

I had my CO2 scrubber working with relatively fresh media. The pH results were steady.

I then added a recirculating device. The pH slightly DROPPED on average.

Then, I took the entire CO2 scrubber off, and my pH increased to a nicer level.

I swear that the more CO2 scrubbing “power,” the worse my pH.

Also be sure to check your pH at the same time of day because your pH changes day to night
