Adding Kalk for pH?

[aaron186]

I’m running triton core 7 flex as a 2 part and have been pretty consistently keeping my alk around 8-8.1. My trouble has been my pH that despite having a CO2 scrubber, my pH struggles to stay above 7.9. I bought a CO2 meter and my levels inside are high. Unfortunately opening a window or running an outside line aren’t practical solutions for my tank location. My growth in the tank hasn’t been great despite good lights and tons of flow.

I have a Kalk stirrer that I could setup on the tank and raise my Alk to 8.5 or 9. Hopefully this gets my pH up and the growth going better. Is this a bad idea? I don’t want to dose more triton since it has other elements in it outside of the basic 2 part.

I’ve been running 2 part and kalk for years. I also have an Ink Bird CO2 meter that measures CO2 in the house.

I keep one window cracked downstairs and one cracked upstairs. I live in Texas and have not noticed any difference in my electric bill.

The windows don’t need to be near the tank, and I bet cracking a couple windows would be a lot cheaper than buying CO2 media for your scrubber.

The addition of kalk will greatly raise your pH to desirable levels. It will take some tweaking. You will most likely be adding less of the two part as kalk also will add alk and cal. I don't kalk 24/7 and those two part just to top off the levels.
