Derasa troubles

[clown and friends]

Hi I've had this clam for a year or so and its been booming, growing like crazy. The last couple days however it looks like this:

Ran some water tests and came out like this:
Ca: 410
Dkh: 12 (high)
No3: 20 (high too)
PO4: 0.06

Did a water change two days ago to correct these and things have not improved. Any thoughts?

Any possible fish nippers? Flame or other Pygmy angel?

Good question! I had a flameback angel which did cause problems and got kicked. Currently the inhabitants are two clowns, a lawnmower blenny, yellow watchman goby and a royal gramma. Any of those known to cause trouble?

Alk is definitely high. Slowly decreasing the dosage and test at least once two days to get it stable. I won’t worry about nitrate being 20 ppm though

They are probably ok, but keep an eye on them.
