Cal 450
Mag 1400
1.026 salinity
Temp 78
Ph 8.0

Nitrate and phosphate levels?

 

[Reef257]

Nitrate close to 0
Phosphate 0.03

Can less flow cause issues

When I get new zoas I put them in a darker spot on the sand bed at first . Some zoas don't like a lot of light and will melt. In time you can try moving them up in the tank.

Salinity a bit high as well as mag

Moderate light and decent water flow, ph 8.1-8.3, salinity 1.025, phos < .05, nitrate < .03, temp 77-79 and feed 2-3X per week.

You can also add iodine to water which perks them up. Lift the plug its on and assure there are no bugs or eggs underneath it. White Light intensity seems a tad bright.

I think il try moving it .to a lower light area and check .is there any chance of we overdose iodine .I have not dosed iodine before .

but my other zoa in the same rack looks rocking .

My best guess is lighting, or the change from where you got them to your tank. Your parameters are decent, I noticed my zoas do better with alkalinity a little higher. 1.026 is just fine, I always shoot for approx. 35ppt. I would move them lower for the time being.

Pull them first, give them a bath in iodine, then put them back in a lower spot.

A "bath" - just put some tank water in a cup. Add say 4 drops of Lugols iodine in the cup. Place the zoas in the cup, similar to a dip. Leave them in for 10 mins. Remove them into another cup of clean saltwater to rinse them off, then place them back into the tank.
