How To Raise Ph And Lower Carbonate Hardness

I tested my saltwater yesterday (60g) and I got good readings on the nitrate, nitrite, and ammonia. The problem that I had is my ph was only 7.5, and I'm getting some clownfish soon and they like it around 8.
I also noticed my carbonate hardness was up, not sure what it was because I was using test strips to read, but It was up in the tank.
I want to know how would Iower the CH, and Raise my PH in time for the clownfish.
There have been 2 fish that have survived ever since I got the tank, I don't know how but they have.
But everything else in the tank tested fine besides those two.
I know this is worded weird but I don't know how to explain it, thanks!

Actually, you’d need to raise your KH (not CH I'm not sure why its not) and your GH. Even with freshwater I’d recommend the liquid tests, but with salt water it’s absolutely crucial.

Well with the clownfish the ph is to low, but how would I raise the kc then?

Yeah you want to raise your PH, you do that by raising carbonate hardness via KH buffers. Something like Kent Superbuffer dKH would work.

I have some hard corals, clownfish, brittle stars, gobies, chromis, and a watchman tang in a 55 gallon tank

pH drops to 7.95--then I add buffer and get it to 8.1--8.14. Two days later it is back down to 7.95. I add fresh seawater at least once a week (5 gallons at a time) from 5 miles offshore.

Anything I can do to better stabilize the pH?
