I'm kind of confused as normally the PH is supposed to be too low in a saltwater tank which then means you need to add a buffer. I'm having the opposite problem, my PH is too high at 8.8. Alk is at 3.5 meq/L.

Alk too high? I've done two seperate water changes trying to get the ph lower. both of which were probably 20%........RODI water / Instant Ocean salt

Sounds strange because your alkalinity isnt abnormally high, and usually ph and alkalinity go together, i would also test with a different kit.

I would let it sit, and see what happens. The natural drift of pH in most aquaria is down. Tell us what it is after two or three days...
