View Full Version : Where to introduce zoas to a new aquarium?

01/28/2017, 05:26 PM
I just set up a new aquarium. I bought a package deal that included a lot of corals. I am using the same lights they were under, but a different tank. Therefore, the depth of water is different, locations, etc.

When I put the zoas in, I usually try them out several places, trying to find a happy place for them.

The problem is that if they don't open, how can I tell if it's from too much light or too little light?

How can I tell quickly (in a day or two) if they are in a good place?

For example, I put in some palys on the sand, in direct lighting, and they barely opened. After a couple days, I put them in a little shade, but still on the sand. They seemed to open up a little more. Are they getting used to the water, or did they just get too much light before?

I also have set my lights to 50% intensity for a 5 week acclimation time. Is this too long, too short?

What I don't want to do is take so long to find a coral's "happy place" that they begin to get in poor health.

thanks for any tips or advice.

"New aquarium" is the most obvious problem with your unhappy corals. IMO aquariums should age at least 6 months before adding corals. How can anyone here help you with the little amount of info you provided. Type of lighting, tank size, water testing results etc. There are a lot of skilled reefers on this site that would be happy to help you out but we need more to go on.

Best to put them low with medium flow and wait a week or two before touching them again. Try keeping out of the tank, and leave stuff alone as much as you can. Back in the old days we would use fresh live rock that would be covered with zoas- and cycling would be a horrid experience with the mass die off from shipping, but the zoas usually survived. You should always provide water parameters when asking questions, if you expect more than a general answer.
