LPS suddenly not doing so good help!

[Alvin88m]

So recently one of my acans and my kryptonite candy cane coral are not looking so good. They both used to be one of the best corals I had their tentacles would be out every night an during the day they would puff up really big and look healthy now about a week a go they're haven't had any tentacles out or just doesn't act like they did. Water parameters are good. Except the the salinity level is at 1.022 I just did a water change to try and raise but it didn't work so now I'm using salt water for top off. I've also been fighting to bring my magnesium up for about 3 weeks now and I've finally started having success. Does anyone know what could be wrong with my LPS'? One thing I've noticed on the acans is a black little dot that sticks out on one of the heads any ideas?

i like to keep my salinity at 35 ppt personaly....when my candy cane and duncan start to retract and act a little funny that usually means my nitrates creepers up a bit

I've checked my nitrates and they're at 0. It's really frustrating because I can't seem to figure out what's wrong with them. I'm slowly trying to bring my salinity to 1.024.

did you recently move them or changed anything with your lighting system

 

[Alvin88m]

I moved the candy cane after he wasn't doing so good. Now slowly all my other corals aren't doing good either. My lighting is new I have jbj trinity t5s. I just took picture of all of them I'll post them in a minute.

the salinity being that low is not good for the corals. slowly bring it up. dont jump too fast. do it over a few days using the salt top off like you mentioned.

did you say you have new lights? that could be the problem. they will adjust eventually. you should have limited the photo period for a little while to let them adjust.

is the temperature ok? has anythign been walking on them? the more things touch my corals, the worse off they seem.

The lights I got them with the tank. They're a couple months old. How long should a be running my lights on a daily basis?

The temperature range from 78-80.

And I had a couple peppermint shrimps that have been bugging the crap out of my acan. I was able to catch one and I threw him in my refugium. Still trying to catch the second one. But I've brought the salinity up to 1.023 and gonna keep bringing it up till I get it to 1.025. Earlier today I finally saw the acan bring out its tentacles.
