for the past 2 days my duncans polyps havn't been extended during the day but come out at night. I noticed tissue recession and did a water change yesterday, and fed it. I got out all the problems that could have been messing with it. I'm wondering if I should did it in Iodine or just let the coral be, and see what happens?

What are the parameters of your tank. Ie: ammonia, Nitrate, Phospate, KH.

 

[blkhawk10]

pH - 8.0
Nitrite - 0
Nitrate - 0
Ammonia - 0
KH - 8
Phosphate - 0
My pH was 8.4 the other day when I first put the coral in, would that maybe have something to do with it?

if its not opening during the day but opening at night I would say the lighting is probably too bright, and its staying closed to protect itself from "sunburn" try shading it a bit and see if that causes it to open during the day.

what about the tissue recession? The base is turning white in some spots.

What kind of lighting do you have and where do you have it placed in the tank height wise?

I have a 150 watt metal halide with a Phoenix 14k, and a 35 watt PC sunpaq actinic. I have it on the bottom in the sand. I also saw some slime comming off of it, I don't know if it was from one of those worms that let out the sticky web though.
