Calcium, ALK, Mag and a mad hammer.

Calcium 390
ALK 12 DKH
Mag 1260

I have to get something to dose calcium it seems as I just did a 10gallon water change which about 15%. Could the low calcium be making my hammer ticked?

My only other thought is that I removed a bunch of old miracle mud from my sump(never again btw) and there is some I'm working on using a polishing pad to remove from the water column.

Third any suggestions for a good reef dosing chemical to keep these in check or do I need to dose them individually.

The calcium is within range, although it wouldn't hurt to raise it to 400+.

I personally don't like alk to be that high. Are you dosing alk or adding buffer, or just using a salt with high alk?

I don't know about the mud or abrasive.

Could be lighting, or flow, or something picking on it.

For a Ca supplement, a bulk calcium chloride supplement is a good way.

There are other factors not being considered here. Nitrate and phosphate? Lighting? Placement? Flow? All can lead to unhappy coral.

Nitrate and phosphate are both low but they have to be there since I have some algae growth. Waiting on a more precise test for both of them as I can't tell the color is some or none.

Just using reef crystals for my salt mix. I did have a dip in all about 3 weeks ago and did a small baking soda dose. It's been stable since then.
