Has a 30gal sumo with sand coral pieces and mangroves. Has a skimmer with flow rate of 500 gph. I use ozone. Orp is about 350. I can't seem to keep ph up. Between 8 - 8.1 with additives temp at 77.0.

What happens before they die? Do they stop eating? Do they get spots?

No spots. No they just are gone or die sixline seems ok this morning. I put reef builder and ph goes to 8.3 then bk down. I I two meters and I tested it so it's accurate

what substrate you using?

In tank sand. In sump sand broken coral

I want to buy more corals and fish but not until I find out the issue. Does ozone drop ph?

How many powerheads do you have? if you point them up towards the water surface you can increase Ph that way. Also, how frequent are your water changes? The salt mix should help keep your ph in check as well.....
