My palys are closing up.

[rockbender]

I just upgraded tanks to this cube I traded for a 1st gen iPad back in November. Everything has been goodi do 5 gallon water change every Friday.
(No skimmer)
Phosphate reactor with media for phosphates.

One morning I came out and noticed all my polyps were closed.
All of my polyps reopened after a couple of days except for 1 bundle of palys.
They seam like they want to open but never open all the way. They can be seen in the middle. They were super bright greenish blue color now their color is gone only their mouths are green and the rest is kind of white.

Any ideas.?

Do you test for nitrates and phosphates? Whats your salinity? Or everything else for that matter?

 

[nasotang]

Are you dosing any iodine? It's in your water for water change, just a thought...

 

[rockbender]

Nitrate 0
Nitrite 0
PH 9.0
KH 240
Salinity 34
I could find my alkalinity test.
No I am not dosing.
I've always had good success with just water changes on previous tanks.
I wanted to go get a couple of frags this weekend but kind of worried now.
So should I be dosing?

KH is alkalinity. But 240 sounds more like CA and if so, it's too low.
Also 9 ph is high.
What kind of salt are you using? Maybe a bad batch? Also what kind of test kits?
I'm having the same problem with my zoas but it is because my water is to clean. I've increased my feedings and was already feeding well, but can't seem to fix the problem.

when did you change over to led.

I meant to ask this, too... the white on your polyps sounds like light shock to me.

Sounds like the LEDs are too strong for them. Lower the intensity for the LED

 

[rockbender]

Ill raise my LEDs higher. They were in the bottom of the tank when the started acting up so I moved them higher.

Ahhhhhh you know what. It started a little after I started opening my blinds in the morning and the tank gets direct sunlight. Could that be too much light???? I started this when the house was dropping down to 36 degrees in the living room.
Salifert test kits. The Alkalinity kit was not in a box so I called it KH. Sorry stuck on stupid on my part.

I'm also feeding about 2-3 times a week
