Melting Zoas

[Monty06]

So I have 3 frags of different zoas in my tank that have been literally melting off the plugs they are on. They still open during the day but slowly are falling apart and cant figure it out for the life of me. Water parameters are as follow:

Cal - 390
Alk - 2.9
Mag- 1400
PH - 8.3
Phosph - .02
Nitrate/trite - both 0 and same with ammonia
SG - 1.026


Any Ideas what is going on. I know Cal and Alk are a little low but they are not aweful. Do coral have a "lifespan"? Everything else is doing good.

Your alk should be 7 or higher.

My bad its 2.8meq/l which equals 7.84 dKH

How u test u sg

 

[Monty06]

I use a refractometer that was just calibrated today, I'm stumped because they were growing very well then came to a complete stop

 

[madjoe]

Hmm drop anything in tank maybe stray voltage or pump corroding in tank

 

[Monty06]

How would I know if there's stray voltage? Can I stick my probes of my multimeter in there to test? Lol

Yep use a multimeter

Oh no shit, I was kidding. thanks mj I'll try that out tomorrow

Also what u lights and temp

 

[Monty06]

I've got a rapid led setup, though I just switched drivers to use with my new apex and haven't dialed them in yet. Perhaps they are getting too much light. Temp is always from 78-80
