low ph

[evan47]

I set up my tank a few months ago and the ph has been consistantly low at 7.6 on the red sea test kit.

I was hoping that it would have risen by now without any messing around but no.

ammonia and nitrate are both 0, nitrate a little under 10. phosphates .16 ( but lowering ), alk 9.

live aragonite sand, live and ceramic rock lfs saltwater and ro.

i have a powerhead rippling the water nicely, the tank is lidded but has a decent gap.

how to to raise the ph to 8.1?

Don't chase a pH number. Do you have adequate surface agitation and/or a skimmer? Is your house sealed up against the weather? It could be a high CO2 concentration.

Mine was 7.5 for a long time so I removed my fish and add in a c02 absorber setup. It worked. My ph went back up to 8.1. I guess my house has too much co2 in the air.

honestly do it the natural and free way, Open a window to let C02 out your PH should raise up.

+1 on opening a window. I stay in a small apartment, and if I don't regularly open a window my ph drops.

Get a different test kit. 7.6 is almost impossible to sustain without directly injecting C02 into the tank, aka malfunctioning calcium reactor.
