Zoa's not opening fully or at all

[Erics210]

OK, Have the two A360WE Kessils and Fluval 2.0 Reef in between, and ordered a package from Aquarium Depot. Chalices are looking good, but many/most of the zoas are not opening up all the way.
I have them on the bottom of the 29inch deep 210 gallon tank.
I have the Kessil settings on Active 1.

Shipment from AquariumDepot. Shipped & Arrived 2/17(8 days ago)
I purchased about 10 frags of 10+ polyps and a larger colony of radioactivedragons eye with 200+ polyps.

Recently added new lighting for me, but prior to purchasing the zoas.
Have one Kessil A360WE at each end and a 3 foot Fuval Reef 2.0 LED in the center of my 6 foot tank.

List the current/flow, even lighting when applicable.
I have a Tunze 6205 on the right side and dual overflow and returns with PanAm HD40s. I also have two smaller powerheads near the surface on each end.

Additives: None at the moment.

I have the polyps at the bottom of my tank.
Tank is a 210 gallon, with a 29inch depth.
I have been using ACTIVE 1 automatic mode that has a varying intensity but color stays kinda Blue, so not as intense. Think the Color maxes out at 30-40%. Intensity has been going up to 80 & 100%

For Me
Temperature - 80 Degrees
Salinity - 1.025
KH-9cKH, 179ppm
Calcium – 600
Magnesium - 1410

Should I change the light settings? Should I increase the intensity/color?
Should I move the Zoas to a higher location?

I dont know what the Aquarium Depot uses as a light source or depth in their tanks. Sire it woul dhelp to know...

Any suggestions?

Out of the 8 frags/colonies I receives, only about 10-15 polyps total are opening at all, and not all the way.

OK - Zoas are still withering away or not opening fully...
Here are updated TEST RESULTS 2/28/2017

Temperature: 79 Degrees
Salinity: 1.025
pH: 7.8
Ammonia: 0 (maybe 0.25ppm)
Nitrite: 0PPM
Nitrate: 40-80ppm
About to do my bi-weekly 40 gallon water change and filter sand bottom so this will hopefully drop a bit.

Magnesium - 1410
kH: 9cKH, 179ppm
Calcium – 600 (using Instant Ocean basic salt this time instead of Reef Salt, may lower the calcium a bit as nothing was drawing the calcium when I was using the Reef version previously.



I will do a water test later this evening after the water change.

Things I may want to do is: raise pH to 8.2- 8.4 range.
Last things to consider are FLOW and LIGHTING...

Have Kessil A360WE(2) and a Fluval Reef 2.0 in the center over the glass support.

And Have two return pumps, a Tunze 6205 on the right side of the tank and 2 smaller powerheads at the surface .
Do i need more flow/circulation?

Thoughts?

Your nirate is a bit high & calcium also a bit on the low side. I think some zoa like dirty water. Have you tried to move them? Try to play around with your lighting & water flow

Maybe do an iodine dip to make sure there aren't any pests on them.

Thanks for the reply. I added some Vitamin C as the Zoa page was big on that which created a Skimmer surge and all the waste collected in a week+ was returned into my tank. So may have some part to do with it as well as me skipping the sand filtration last water change.

So that will account for the higher nitrates. WIll have to do my water changes tomorrow morning...Took longer than expected to get my RO/DI wate

I did a Revive dip when I first put them in.

Will have to move em to filter the sand tomorrow, so will move the ones not opening at that time.
