Low PH, high ALK

[D_0827]

Hello,
My tank is fairly new (11 months).
I’ve always had low ph in my tank and high alkalinity but thought over time it would get better. I know many people use kalk. Is there a long term solution for these types of issues?

I’m including a pic of my last test.

coral skeletons would be melting at that ph, if it were accurate. Do you have corals in tank?

I do have corals, and they seem to be doing good. Fish are all fine too. Nothing is melting but corals aren’t growing rapidly either. Every test I’ve done at the lfs gives me the same ph numbers and I test very often

If hard corals are staying alive, ph isn't that low(though it is probably lower than ideal). There are many ways to increase ph, which will speed growth rates. Search "low ph". I would start by getting proper test kits so you can do your own testing and go from there
