Zoas are not happy...

Yes I think your salinity it too low. Also what lighting are you putting them under? zoanthids usualy like it low for the lighting and putting them under high light can make them melt.

They need to be acclimated to the strong light very slowly.

people say zoanthids are beginer coral but they are some of the hardest coral to keep. I keep sps without any problem, I even keep alveopora and goniopora without any problem but when zoanthids decide they are not happy, they just melt away.

I have problem with my zoanthids since I switched salt to H2O, so I am going back to Instant Ocean as soon as I finish that batch.

Before I switched salt my zoanthids were growing like weeds, tripling each week. What brand of salt are you using?

Params are:
Ammonia = 0 or not detectable
Nitrite = 0 or not detectable
Nitrate = 0 or not detectable
SG = 1.022
KH = 142
Calcium = 380
pH = 8.0
Temp = 78-80 F

not running carbon

these params were taken 24 hr after the last water change, i've done 2 water changes in the last 7 day. About 15%-20% each change. I use RO/DI water. The TDS from my RO/DI indicate 0 ppm

What gives????

thanks in advance.
