pH question

[cmsurfr22]

My tank's pH fluctuates between 8.15 and 8.4 on a daily basis. It never used to go above 8.3 until the last few months. I don't do water changes, so I'm wondering if this is the side affect of that? I have a vertex calcium reactor. It's a 60 gallon tank. I run bio pellets. Everything looks fine in my tank. I run my fuge light during the day. Any ideas on what I should do?

You open your windows more often?

So by opening the windows there would be less co2 in the house which would raise the pH.

Yes, fresh air increase ph.

i think he want ms to lower his PH cause it is going above 8.3. I would run the fuge light opposite your display lights. It should help your peak PH go down a bit and level out the daily PH swing.

Calcium does not directly effect pH, but it interacts with alkalinity which in turn can effect pH.

if everything looks fine i would just leave it alone.
