Magnesium:1500+
Ammonia:0
Nitrite:0

Is brown color stn? How old is the tank, how long have you had the slimer.
Brown might be high nutrients and low light.

Hi, by looking at your parameters it seems you have high nutrients as well as high alk and cal numbers i would do some water changes and try to get closer to natural sea water numbers

The STN is at the base, it could also be aptasia ticking it off. If you look closely, you might just be able to make out the dead skeleton.

Hello. For the past 4 weeks, I’ve been doing 33% water changes, but the nitrates are consistently stuck at 25 ppm. I just started running phosban.

Your cal,alk, and mg are kind of high. Check your salinity. Calibrate your refractometer with new 35ppt solution, then check.

If your salinity is high, discard cups of tank water and replace with fresh water until salinity is where it belongs. Do it over a few days, not all in one shot.
