Dull zoa

[Bcountry]

Hey guys I have eagle eye zoa's. I have noticed the zoa's have become dull since about 7 months ago. All parameters are perfect except calcium I found out today that the calcium was 370. Could this have something to do with the dullness?

Do you do your weekly or bi-weekly water changes ? From what I understand (not a professional) just based off of previous questions the calcium isn't as important as proper water changes and good lighting. Maybe your lights are set to high possible bleaching/stressing?
Many pros will want your water levels?
Lights used?
etc..

Do you dose iodine? Zoas will fade if they are not getting enough iodine & if your water isn't dirty enough.

Here's a good read... https://www.reef2reef.com/forums/zoa-discussion-club-zoa/19066-dosing-iodine-iodide-zoas.html

I don't dose (never have) I supply proper nutrients with weekly water changes so, if you have fish in the tank that's another reason to just be extremely careful and testing before dosing would be recommended IMO. Overdosing is very simple and possible.
+1 on the dirty water(not dirty just not as clean as some other corals may like to be 100% happy.

10 gal nano, 1.024, dkh 9, calcium 370 (just found out this is really low), ph 8, haven't tested mg, 78degrees

How's the other parameters? Kh, PO4, NO3. Look all coral need trace elements & not all salts carry the correct amounts of trace elements as they state, so dosing trace elements will benefit the coral.
Just my 2cents
