My favias are never open.

[IanStocker02]

About two months ago, My favias started to close up. nothing changed (parameter wise) and they just closed and dont seem to be doing well. they still have their color, but I dont see any tissue expansion, not even at night. I dose with kalk in an ATO, niTRATES are 5, Calcium 400, alkalinity 8dkh and phos 0,1. I dose Iodide,magnesium and trace elements. since the favias have closed up I recently started to do more maintenance because they aren't looking as good. I've been doing water changes probably every week now for the past 2 weeks. everything tests fine, I don't know why they look like this.

I mean, they don't look terrible... Anything potentially disturbing or picking at them?

they look okay, maybe too much PAR?
