major issues with sps after correcting salinity

[Paulairduck]

a lot of my sps tissue is peeling off after correcting my salinity, it went from 1.034 to 1.025 over a period of two weeks, due to a bad refractometer, I finally got my salinity corrected and then my calcium went way high 500+, I am guessing as a result of the salinity being very high. I have everything in line now and all my sps are under major stress!! would this be the cause??? everything checks out otherwise


current params

alk 8.0
cal 450
mag 1300
salinity 1.025
nitrate 0
po4 .05

my salinity swings off and on but it never stress's the corals out that much as water evaporates and i sometimes forget to put water back in but this is done over time slowly so they adapt..are you sure you have no aefw or red bugs? i went thru a similar event where i thought it was the salinity then was told it could be my circulation i have 3 vortechs so wasn't that then told the lighting could be old bulbs or new bulbs etc..killed 2 weeks things got worst then i found the bugs with a baster blowing on the corals revealed them coming off and the war started i am loosing a major colony of purple millepora and a green acro so saddened starting a qt tank and dips this week , but i wish someone would have said hey baste the corals and check for bugs in week one not week 4 when eggs where laid and bugs taking a foothold.in my tank

I have been through every pest in the book, that is not it, the tissue is receeding from the tips sides and body, never seen this before. Looks to me like the major swing is the cause, it is showing on all my sps.

You need to realize that your SPS encountered stress when the SG shifted from low to high, but then again from high to low.

Factors being the degree at which they are used to such dynamic shift, the sensitivity of the species, the degree of magnitude of the shift, the time for the error to occur, and the rate at which you corrected the level, all of this along with the initial stress prior to the event all at up to what you are seeing.

You are experiencing the latent effects that quite possibly were already set in motion, or the secondary shift when you corrected it triggered everything.

Minimize any further changes, frag if you have to and hopefully it may slow down or stop....

What else shifted at that time? Did you recarge your phos media or raise any other important params? are you dosing anything, bacteria, carbon source? Change carbon, lower nitrates?

I would guess you found that the refractometer was off when you started to notice the coral looked bad. This being said I would say it is a result of the stressing. Hopefully some TLC will bring them back to a good state. What are the current params?

yes it was deffinitely the major shift in salinity, my params are in check, did a little fragging, hopefully the worst is over.

Sad day, over a bad refractometer:bum:
