Bacterial infection?

[All Delight]

Any thoughts?

I have had a 3 pieces of micromussa die over the last 3 months. It starts with one polyp decaying. Over the next 3 or 4 days, that polyp will be gone and I'm left with a skelton. Then it'll continue to spread until the entire piece is gone. I had a 5 polyp frag die in about 2 weeks.

I keep mostly lords and micro, some ricordea, a couple chalices.

I have 2 fish, blue assessor and a tail spot blenny.

Someone told me sounds like a bacterial infection, since its spreads so quickly. Plus its isolated to a specific coral at one given time.

But as one piece dies, it seems to start with another one a week or two later.

My params seem fine.

salinity 23
amonia 0
nitrate 10
nitrite 0
phos 0
calcium 420
mag 1230
ph 8
alk 7-8

If your salinite is 23 then you have a huge problem. Now, if you meant your specific gravity is 1.023, that's not so bad.

That nitrate reading is some problem, could be cause, ph a shade low [8.3]. Alk better at 7.9 or a little higher. RUn carbon, do 20% water change, retest. Also, if you have any algae, you have phosphate: it binds up in same, and is undetectable, but still in position to be a nuisance.
