Zoa stretching - besides light what else could cause it

[ewanho]

Besides lighting, what else causes zoa stretching?
Could there be a trace element missing? Or too high?

so for one small tank, the light is quite good, mix if T5HO and led;

nitrate 10-20
Nitrites 0
Phosphates 1.0
Hardness 10-12
Alk on the high side ( cant remember)
Ph 8.0
Mg 1500

I noticed stretching and buttoning for months associated with high nitrates. Also in this time i lost a lot of zoas to some sort of infection coupled with zoa pox too.

Whats your iodine level at?

 

[Reef.]

Not read up a lot on iodine, maybe take a look at that as the little I have read seemed to be mixed options whether it’s useful to supplement.

Had it tested by a LFS; said it was 0.02 and told me to dose a few times a week; also they said the teat kits are not reliable; feel like a guessing game

Yea my icp test showed .019ppm of iodine.
Recommened range is .058 according to them.
I just bought the salifert kit that reads all forms of iodine.
