? On polyps being small

[fastest302]

Hi everyone hopefully somebody can chime in.. some of my zoas look like they shrunk especially rainbow incinerators
Hallucinations
Spek krak
Space monsters and so on
I’ve moved them around to see if anything g changes but nothing lighting been the same flow hasn’t changed I’m stumped did a icp test and that came back good but the iodine being low..

Also I’ve seen pics of zoas with nice lashes and I have zoas with no lashes on them

ive noticed that when this happens, its always water quality and its always something you cant test for (if all your parameters are in check.) I would try to bubble scrub for a few hours right before you do a water change. this usually helps if you do weekly water changes. possibly something you can try.
