Red moti cap turned white

[TK_KW]

I have a large frag of red cap. Been completly fine for months. Just noticed it has completely lost its colour. Skeleton showing completly minus a few spots. All other sps,lps doing great.

Also noticed yesterday a large trocus snail got on my top frag rack and plucked of bunch of polyps from one of my other sps frags(dont recall name, but when extended looks like yellow flowers) dark stem.

Is it possible this large trocus destroyed it?

Unlikely it was the trochus snail. We need more details like ph, calcium, alk, magnesium and not just salinity and phosphates.

Cal 505
Mag I dont test
Ph 7.95

It's a 48 gallon frag qt. 30% Waterchanges every 4-5 days roughly. Which keeps levels stable. I use Salinity aquavitro salt

Two things, ph is too low, needs to be 8.1 - 8.3. and calcium is also to high and your. Levels are not stable. They seem to be out of wack

PH would have nothing to do with it. Especially at 79. Mine drops to 79 with windows closed and goes to 8.2 when open. Post some pictures.

No. You want your ph to be at 8.2 regardless. It's fine if it swings throughout the day, like ph is supposed too, but you don't want it to be dependent on if your window is open or not. I need more info and not just calcium and ph and silinity. Because calcium is so high, the other concentrations of other elements in the water will be high or low too. Sps are sensitive to things like that and it has to remain stable.

I doubt it was the snail. It’s surely wasn’t the ph. Do you have pics of your other stuff? How old is the tank?

 

[tehmadreefer]

Agreed its certainly not the ph... I have tested mine in years and unless ph drops below 7 then you mighttttt have issues.

Need to know your po4, no3 and alk. Cal is way too high.

 

[Style185]

Send a pic. What other sps are in tank that are not affected?

 

[Jinko]

Could be lighting, either too much or not enough.

I doubt it PH mine runs around 7.9 and although not ideal it's hard to maintain a pH of 8.2 in doors because of carbon dioxide.

Montipora caps are fairly Hardy as far as sps go so I would start looking at ammonia, nitrite and nitrate perhaps.

FWIW - I lost a piece of red cap very quickly to montipora eating nudibranchs. It happened after I removed all of my fish in preparation for a tank move. My guess is that my yellow coris was keeping them in check.

 

[ckalupa]

The other thing on top of parameters- have you made any changes to your lighting?

 

[TK_KW]

-Qt tank 2.5 months old
-Lighting has not changed in months.
-I measured par, Top rack is about 120 par. Lower rack around 90 par.

Red cap was up beside birdsnest for almost a month and no problem. I've since moved the red cap down. I'm new to reefing and could use some guidance. Thanks

Looks a little close to the acan colony and torch to me, both are pretty aggressive corals and have some long sweepers.

 

[Fudsey]

I would bet that acan is stinging it. You should move it away from it.

 

[Stuartmercer]

That would make alot of sense if it is the acan

 

[TK_KW]

They was NO acan near it.I literally just moved it there today, I'll move it. It was up with all the other sps with nothing near it.

Will it regenerate if it was being stung?

 

[TK_KW]

There was a ultra platygra frag right beside it?

Platygra frags extend a long sweeper tentacle to kill neighbor corals. So yes it probably was the platygra. Move the platygra frags and.leave the Monti alone. The coral might heal if your lucky, leave it alone for a while.

 

[jsak1976]

Monti cap is an SPS anyways they need high light and high flow, I would move it back up to where it was before. Does it have any color left? If not it won’t recover.
