Zoa help

[Raidensreef18]

I have a lps dominant tank and everything is doing very well minus my zoas . Some are doing well while others are either curling and a few even melting away .

With out hearing any parameters of top would you suggest checking into ?

Euphilla ,wellso Sunkist bounce and other mushrooms, acans , gonis, space invades, all doing well . Many zoas as well . Just a hand full and randoms not .

Calcium 400 range
Dkh 9 range
Last time checked no3 was 10-20 range
Phos was under .5
Salinity 1.024-25
Temp 77-78

These are ranges simply bc this has been the last 3-4 test numbers while the zoas have struggled .

I did have some swinging parameters about a month ago which the zoas were the only thing that showed signs and hasn’t shown any progress since .

Your phosphate is way too high. I’d reccomend Hanna checker for phosphate and nitrate. It gives a digital parameter reading rather than trying or compare colors. Shoot under .1
