Zoas not opening

[nani223]

Zoas still won’t open these are my parameters any advice?? 5g nano no fish only zoas


someone told me to add a fish for some more nutrients this a yes or no?‍

Fish or dose. If you want coral only that tank would take pennies a day to dose.

Alk is good. Mag is a bit high for my liking and calcium is a bit low however I don’t think either would be causing your issue.

Are they new zoas? How old is the tank.

Can you try dipping them again? What par or light set up do you have in place?

I would consider adding some clowns or something to help with phos

I just had a problem with multiple zoas not doing well in my new tank. Turned out salinity was way high due to using a cheapo swing arm hydrometer. They are pretty shrivelled and damaged by the pickling experience but are trying to open again now the sg has hit about 1.030 coming down.

Phosphorus and nitrate are too low for zoas. Also could be on the verge of a dinoflagellate outbreak which would also cause them to remain closed.

I concur water is too clean. I would dose for immediate impact and add a few hardy fish. Assuming the tank might be new?

Hi my tank is fairly new it’s only been running for about 2 months and the corals have only been in my tank for about a week, I have a fluval nano desktop light at the moment.

What would you recommend dosing ? And yes most definitely planning on buying a clown soon.

I’m planning on adding a clown but what would you recommend dosing?

I'd try bringing your nitrates up a bit. Softies do better with nitrates

If this is a new tank, you are going through various changes in chemistry and need to build nutrients without overfeeding. It can be to too much light or water flow, sudden change of parameters as mentioned and assure salinity has not become elevated. Often a simple dip in Lugols iodine can perk them up. Run moderate flow which is ideal but Zoas which can adapt to low or high flow. In high flow, you will typically see polyps grow closer to the rock with shorter stalks.
For parameters, good water quality is a must.
dKH: 8.0 - 11
Calcium: 400 - 450
Magnesium: 1300 - 1350
Iodide: Maintained via regular water changes or manually at small dosages
Temperature: 78-79 degrees
pH: 8.1-8.3
Phosphates: .04 - .08
Nitrates < 10

Thank you!

I would consider the problem to be
Dinos
Lightning.
Vitamin C shortage.

Possible solutions
Vitamin C dosing,
Uvc or other way to battles dino.
Feed reef roids with those low nutriënts.

They seem to do well in high flow .
