White slime on Zoanthids

[Alex’s Reef]

Okay so I have a 23 gallon frag tank with 1 Kessil A360x tuna blue and 1 Kessil 160we tuna blue, a Nero 3 pump with a sicce whale canister. I am dosing .9ml of RedSea’s No3Po4x a day as well as vibrant every two weeks. I bought 4 zoanthid frags from my LFS and dipped them all in freshwater iodine solution and ever since I got them they are not opening up. I noticed on some of them there’s a thin white slime coat and one of the small zoanthids there’s some stringy white stuff over the polyps. Can someone identify what’s going on? Maybe this is an effect of the no3po4x? The water I used to mix my salt in is from my LFS and the RO water’s tds is coming out as 3. In the frag tank I got it out of the tds is 0. Is that too big of a difference to keep coral from my LFS frag tanks?

zoa's in general are very hardy and can tolerate a wide variety of parameters. if they are new frags, just give them more time to acclimate. the picture you provided is a bit blurry/too blue. perhaps if we got a clearer picture under whites we could help more.

Sorry about the photo quality, I should have thought about that. I bought these zoa frags on Dec 29th.
