Montiporas

[ajackson3036]

I have a few montiporas that we have had probably almost a year. One started dying off then the other. They are turning white. The light has been the same for over 2 years in this tank. They were thriving. One day the salt was high but we caught it the same day. They were growing back now they are doing the same thing and none of the water test are showing anything negative. What else can we do?

Alk spikes by chance?
High flow and low calcium would also do it

Can you post parameters? Could be a number of things. Any other corals, specifically SPS? Pictures of the montis? Have you ruled out pests? Take out of water and dip to see if anything falls off.

Sounds like a swing in something. Posting your tank levels will help.

Any nudibranch's in the tank.
They can come in on frags/corals as eggs.
They will turn your montis white and are hard to see.
I know as I have had them.
Montis looking good for a year then bam nudis attack.
Post some pics!

Hey guys i have had montipora frags for about 3 weeks now and i cant figure put why they continue to bleach or dont regain color. Also, my bowerbanki frag began dissoving and exposing skeleton about 1 week ago now. I will admit there were some swings in the early stages of introduction due to dosing by hand. Now i have a dosing pump which is keeping everything close to stable. Any thoughts on what i should do to preserve these montipora and bowerbanki frags ?

Levels:
phosphates 4ppm
