Raising PH in Pico tank

[misoldier06]

Hello all,

Problem is, I've got a 3.5 Gallon tank that i dont know how to raise the PH in. My PH in the early morning before lights turned on was 7.27 and at the end of the day was 7.47. DKH was 7 and cal was 360. Within acceptable ranges. I'm not sure how to tackle this problem on such a small tank. Dont have enough room in the filter chamber for a Mame like skimmer, so i cant really hook up a scrubber. What else can i do? Will raising the DKH make that large of a difference?

I do not believe those values are accurate. Calcium carbonate rocks and sand would be dissolving, raising alk and pH.

How are you measuring pH?

With A PH Pen. I calibrated before using.

I expect it is incorrect. Calibrated at two points, 7 and 10?

I have a 2 gallon pico. I run an air stone up to max for maximum agitation in the tank and run a little calwasser every other week and my ph stays around 8.0 to 8.3 on beginning of light period to ending of light period. And I test my ph with a test kit, electric probe, and ph monitor.
