SPS not looking good

[Frankysreef]

Once I dropped my alk my STN stopped. And my corals are starting to heal. That was it... no other thing.

What's the temp and are you sure? have you double, triple checked it with other meters? What's the PH and are you 100% sure about that? SG is what? Not talking down to you, just asking if you've double checked all these.

Ditto on rechecking these basic parameters... I had some issues earlier in the year because my salinity was WAY off. Apparently, my refractometer was not calibrated correctly and was giving me incorrect readings. I was doing water changes (for who knows how long)with the salinity way off.
