Frogspawn keep melting... Help

[Junmity]

I have a 120g tank that has been set up for 3 months....

I have two frogspawn that i've had for two months that are healthy but when i introduce any new frogspawn or hammer, they melt within a day......

Here are a couple pics to show the progression of the last one i introduced. I love these coral but hate losinging them as i've tried several times to add more. each time with the same fate as this one.

All start the same...
2 hr aclimation
start to shrivel on intro to tank
white slime starts to string across
begins to recede at the base
several hours later the skeleton is exposed and its' all over :(

Nitrate 0
Amonia 0
Nitrites 0
KH 9
PH 7.85
temp 79F

what are you using for lights??

[Junmity]

I have a 72" coralife PC's 588W total

What's you're salinity at? May also want to raise the Ph with some buffer. They are usually pretty hardy but maybe they were already in decline before being added to your tank.

Salinity is 1.023

I just bought a calcium reactor to try to bring it up

but i've been dosing twice a week with reefbuilder.

The strange thing is, i have two frogspawn that are pretty healthy since the beginning.

when i add zoa's they do usually close up for a couple days to a week before the fully open and start getting good colour.

Likely gets damaged in transport. If the frogspawn is not deflated as it is removed from the tank then the water it holds can weigh heavily on the tenticles causing a tear. They just may not recover after that.

I really want to believe that buy i've gone through this 4 times and take extra care, even floating them to get them home without rips....

here's a pic of one i've had for a while.

My thoughts would be too much flow.

LPS prefer lower flow and almost any light is sufficient.

thats not good either zoas should almost open immediately ,thats also a sign something is off.

My thought would be the ph, have you checked the ph of the water your frag was in prior to putting it in the tank. If it was at say 8.2 to 8.4 then goes into your tank with a ph of 7.9, that is a huge swing. The corals that are in there already probably got used to the declining ph over time.

Not sure why your ph would be so low. Something is causing your water to be too acidic, hopefully someone can chime in on that.

Never listed what your po4 is at

[paddyob]

Never listed what your po4 is at

unimportant. Algae food mostly.

[Proteus]

I would disagree. I've lost lps of that sort from to high of phospate

I highly doubt it was the PO4 that caused your issues. Just saying.

Anyhow, not going to argue over it, in two hours there is no way PO4 is the culprit.

[Proteus]

Nor will I argue but this is out of a artical from reef builder

Besides fueling algae growth, phosphates can retard the uptake of calcium by calcifying corals. This of course is bad news for reef keeping aquarists who house a lot of hard corals. The corals will slow their growth rates as phosphate concentration rises. Some may even begin to die or have tissue recession. The latter part is obviously an extreme case, but it can happen when phosphates reach higher concentrations. A slowed calcification not only means slow growth, but slow repair when damaged by fragging or hands moving about the aquarium.

Yup. I know this. But it will not kill a coral in two hours. Think of other corals in the tank.

It's not the po4.

Good luck! Signing off.

[Proteus]

Did not see the two hour part pat

My bad

No worries.

Good point on the ph...

Was much higher when the first ones went in(8.2)

Now it's declined. I've been dosing now and just bought a calc reactor.

I'll hold off till I get my ph up the. Try again. I'll update once I do!

Thanks so much for the help!
