Zoa issues

[Savanna’sReefAndFish]

A couple days ago some of my zoas started to loose a bit of their color and just not look healthy. I lowered the brightness of my lights thinking maybe it was “burning them”. Does anyone have any ideas or has this happened to anyone before?

What’s you water parameters? Is it all your zoas? How long have you had them?

Everything seems normal. pH -8 ammonia -0 nitrites-0 nitrates- maybe 20? (I haven't checked anything else yet) but all my other corals r perfectly fine, even another bunch of zoas and they’re perfectly fine. I’ve had those zoas for maybe a year and a half now

@footgal

do you dose anything?
There may be a lake of iodine which zoas use

I dose some calcium but that’s really it. It could be the iodine. I’m doing a good water change TMRO so hopefully that will fix. I’m leaving for college In a few days so I’m hoping this gets better
