Why is my frogspawn dying

Teen reefer · Apr 4, 2021

Hello, I purchased a frogspawn coral at my local fish store yesterday and it looked very healthy but this morning when I woke up I was surprised to see that it looked almost dead so can someone tell me what is going on with my frogspawn coral!
Nitrate: .2 ppm
Phosphate: .08 ppm
Calcium: 500 ppm
Alkaline: 14 DKH
Magnesium: 1900 ppm

your alkalinity magnesium and calcium are all extremely high and it could be responding badly to the parameters, looks like it could be brown jelly disease too but getting those parameters somewhere near normal with water changes would be best.

When was the last time you check your parameters? Do you have a range you typically target 14dKH (alkalinity) and 1900 are very high. If those numbers occurred suddenly it could definitely be harmful to coral

Your dkH may be to high compared with the LFS...

for now i would target calcium at 450, alkalinity at 10, and magnesium at 1400 because that is really the high end of what those should be run at, then slowly decrease more to where corals are good, i like alk 8 and calcium 420 magnesium 1280 personally. What salt are you using and are you currently dosing anything?

Ouch on readings

Should be:

Temp 77-79
ph 8.1-8.3
salinity 1.025
nitrate < .4
phos < .04
Ammonia < .03
mG 1300
Alk 8-9
CA 440

All this being said.... dont go crazy bringing the parameters down. Do it via water changes over the next two weeks. What is your salinity? Im guessing that its pretty high considering that the parameters are wildly high as well.

At 14dKH.... its chemically burning the tissue on soft corals.

What are you dosing to get dKH to 14?
2-part? Kalk? Hard to believe a dry salt mix would lead to 14 dKH

I'd spend Easter doing a 50% waterchange pronto.

My guess is salinity is .030+... hence the elevated parameters. Found it a bit odd OP didnt post salinity, but posted everything else
