Montipora Digitata Problem

[Alitoo_81]

hi, I am having same problems with this coral Montipora Digitata. I dont know why the polips are closed and wont open. note that i have many other sps corals and all of them are very good. I havent done a water change for 2 month now.

the problem is only with the montipora digitata and with the 4 of them that i have. this is a foto of 3 of my other sps corals with no problem at all.

I checked my paramiters all 0 ppm
calcium 420
kh 12
magnecium 1200

pls help thank you.

Alk @ 12 a little hot for digi.

Bring alk down a tad and raise mag to 1300-1350 and your golden

Ok thank you and how do I low down the kh apart than slowing down the calcium reactor?

Lower your co2

My digi does better with alk of 8-9. Anything higher or lower and it doesn't look as good. Especially lower than 8. My LFS told me to run the CO2 at ten bubbles per minute to start. For whatever it's worth.

If you don't use a salt with high alk, the best way to slowly lower alk is by doing water change. If you haven't done a water change in 2 months, I would start doing that anyway. It's very possible your problem isn't related to high alk but a lack of water change.

Did it ever dawn on you to just do a water change? Corals exude chemicals, Acroporas could very well be tainting your water. It won't affect acros, only competing corals (Montis!) Forget being a bio-chemist like these guys, pour some salt and water in a bucket or watch your corals die.

What Softhammer is implying is doing frequent water changes once every one to two weeks, would solve a lot of problems. I just wanted to make sure you got his message.

hi thanks all... the alkalinity is 8.5 and 9 now, and the problem with the montis was not resolved. they still the same with a 5% better than before but the proble is not resolved. the acro and all the other corals are good. i did a 50% water change and i will continue with the routine of 10% water change every 10 days. the problem is also in al the green posillopora too. Can it be becouse i have the aquarium too clean??? I had a algae problem so I feeded the fish once every 2 to 3 days. the algae disapired and breack loosed but did this affect the corals??? I have 2 biopellets reactor. thank.

one more thing I ediet strountium and iodin 2 times before the problem.

I did a 50% water change with no progres or dose this take time?

I have a Multicolor angel fish and now that you mention this I have seen him chopping on them. I thought that he was a reef safe, isnt so??

It depends on how you define reef safe.
I have an african pygmy angel and it nips every now and then on the digi. nothing serious with very minimal damagae but it does cause it to not extend all polyps ( like your photos) isolate or catch the angel for a while and i bit it will get back to fully extend its polyps.
