My acro bleached over night, two others seem fine, nitrate went from 18 to 32, is that enough to kill it

No I’d say it’s probably a stability issue with alkMy acro bleached over night, two others seem fine, nitrate went from 18 to 32, is that enough to kill it

What you have posted is not an acro. Looks like a Stylo.
It probably didn't die from nitrate spike. More likely something else. What are your parameters and how much do they vary day to day?

Are you saying it’s not an acro?

Yes. It would appear to be a stylophora, not an acropora. Not all sticks are "acros".

Stylophoras are thought to be a relatively hardy sps coral. The usual questions of how old is the tank, what's your parameters, how often do you test, do you dose, how much if so, lighting, etc. are needed to even begin to diagnos any issue(s).

Usually alk or phosphate related.

Thanks for the info, care seems to be the same, still don’t know why it’s dying. The temperature dropped in my house last nightdue to gas shut off, don’t know if that would effect the tank. 22 gallon long tank.

Def a stylo not acro. It’s not the nitrates I would suggest instability of something else. Are you manually or auto dosing? What do you dose?My acro bleached over night, two others seem fine, nitrate went from 18 to 32, is that enough to kill it

What's your alkalinity, calcium, magnesium, and phosphates levels at ? What test kits are you using ? How long has the tank been setup ? Do you have a heater for the tank for when heat gets turned off ? How cold did the tank get ? What other corals are in the tank ? Do they look stressed ?

Sometimes it just happens.... You will never know how that was handled before you got it. Montis and stylos are easy to take good care of if the person before you didnt make dirty hand love to it.

Tank is three months old, 22 gal. With sump (10 gal) protein skimmer, chaeto, in sump, kessel led lights ph 8.1, nitrates 32, alk 10.3dKh phos- 49 ppb (.04 ppm) calcium 432. I have been testing 2x a week due to nitrate issues, I had been feeding the corals daily, but was advised to stop feeding due to nitrates, and since they are small. 2 other stylophora in tank are happy. Also noticed a group of star polyps didnt want to come out until I moved them. They have been in the tank for 2 months.

There is a heater, posted parameters, 2 corals near by looked stressed

49 ppb phosphorus is .15 po4 not .04, and is higher than most like to run. Your tank is also pretty new and between that and nutrients jumping around as well as temp swings, you're not stable enough to support sps yet. I would focus on keeping everything stable and getting those nutrients down for a few months before adding harder corals. That other SPS you have in there looks to be a montipora digitata.

i've heard this so frequently but i have a very low survival rate for stylos compared to montis and other sps. i think i've narrowed it down to 1) specific gravity MUST be within their range of 1.023-1.025 and 2) dipping once they're acclimated to the tank since a couple polyps dying can lead to the whole thing STNing.
edit: the advice version of my rambling is to check your salinity. and get a second measurement on a different device if you haven't calibrated your device in awhile.
