Hi all,

My wife and I recently got a 30 Gallon tank (about 7 months ago) for our home. The bubble has been with us most of the way so far and the hammer joined him 4 month ago.

Both corals have been looking progressively worse over the last 3-4 weeks. Water changes are done usually ~2 weeks apart, with little success since things have slowly started to slip. Attached pictures of both corals for reference.
Not much luck. Looking for any insight.

Disclaimer: Baby wasn't cooperative so Calcium was hastily taken (real value lower). I'll retake all measurements tomorrow and update this post.

Red sea test kit.

Tank parameters:

Calcium: <375
Mg: 1520
Alk: 8.4dKH

Have you calibrated your refractometer lately? What are your readings? SG? temp? Nitrates?
