PH drop new tank.

[Notsolostfish]

My 200 gallon tank is in my basement. But my basement have no windows. My PH for 2 days after installing apex ph prove 8.04. After that my ph was 7.96. And after adding fritz turbo 900 yesterday my ph through the whole day is 7.89.

Is that a dangerous ph number? Should i leave it or fix it?

Not dangerous.
Leave it and forget it.
PH measures in hobby grade testing and probes is useless, IMO.
It is what it is.
Playing with PH changes water chemistry.

If you have good water movement and a skimmer, that’s enough.
