Ph is consistently 7.9 - 8.03

I have a mixed reef and never really measured my ph until recently with my new apex. It’s measuring on avg 8.0. Is this ok or should I get a co2 scrubber ?
My acros are very slow grow, but my softies are growing quick (mushrooms, zoes etc)

John, PH has been called the "Brat" of the saltwater aquarium because it does what IT wants to do.
Not to worry you are fine & you will find it rises with lighting & falls @ night.
Also if the home opens windows it tends to rise too.

Agreed, hence why I never took ph readings until getting the Neptune apex for the purposes of the trident.
Iíll just let it ride.
Reason why I asked, I understand higher ph yields better coral growth.

THat pH affects growth has been an assumption for a long time that hasen't held up when researched. Factors that can are feeding, tankmates (alleopathy or microbial shifts) excess labile DOC, lighting, as well as nutrient levels too high or too low.

Here's some stuff you might find informative:

Awesome. Thanks for the links.
It’s funny how there’s so much info out there with no solid answer to this one.
One fact always opposes another.

There are a lot of variables we can't test for yet. Like the innate immunity of a genotype which can vary significantly between differetn genotypes in a species. Or what other tank mates are in a systems, different types of corals promote different types of bacteria in the water. So there's some serious microbial warfare going on in our tanks.
