Need suggestions

So since we have the hot temps and turning our AC on my ph has dropped a nice amount... currently don’t run a skimmer will be adding one this weekend and will be running a air line tube outside to increase ph. My question is how do I keep my ph from having that much of a swing I don’t dose anything currently. I have increased aeration in sump but not doing much. Feel like this way to big of a swing.

One simple way would be to add some Kalk to your ato. Or a simple recirculating co2 scrubber on your skimmer once you get it.

I’ve downscaled my tank used to use kalk all the time my weekly water changes keep my Alk around 8 and very stable no need for kalk at the moment. Maybe I’ll give the co2 a shot.
