Coraline grow on zoas

[Revos]

Hi to all!
I have a 15gallon cube almost a year now with some zoas, acans, ricordeas and some rock flower anemone.
I keep my corals under a kessil a160we at 50% intensity.

I try to keep my water chemistry stable
Salinity 1026
No3 2-8
PO4 0,009 (hanna instrument)
Ca 420
Mg 1400
Kh 8
Ph8-8,3
Temperature 26 celcius

So the problem is at some Point coralline start to spread quikly around the zoa frags. The zoas then stop growing and the coraline slowly covering them!!

Is anyone have the same problem? What u guys recommend?

Thanxs and sorry about my english!!

Yes, I have the same problem in my sps tank. The purple coralline is extremely aggressive. Some zoas don't seem bothered by it but others get overgrown in a hurry. When this happens I remove the frag from the tank and lightly scrub over the coralline algae with H2O2 and let it sit out of water for about two minutes, then I rinse it in tank water and return it to the tank. IME, this kills the coralline. Unfortunately, some H2O2 invariably gets on the zoas as well, which makes them unhappy for a few days or more, although I've never killed any doing this. However, if anyone has a better method, I'm all ears.

I cant think of a good solution. If you are not keeping much sps, you can lower you Ca level and that will in turn liit coralline growth. ... but Im not sure, just shooting in the dark, I know zoas and acan can do away will lower Ca levels

Yes, of course, this is a great solution if you're not growing stoney corals.

I have my montipora and my birdnest coral. How much lower Ca levels? About 400? Or even lower? I will try the H2O2 as well.

I have a pin cushion sea urchin that keeps my coralline algae in check...

It’s very interesting I am having the same problem right now , I have a frag of Rasta zoas (looks exactly the same as yours) I noticed they have not really opened the last 24 hours so I inspected the frag closely and noticed purple coralline plating on one side of the plug … and on that side it’s creeping up and actually half way surrounding the bottom of a few Rasta polyps … looks like it’s pretty much squeezing - constricting then as well as it’s actually pushing into them pretty hard …. I am wondering if you ever found a solution to this I am planning on removing the frag and trying to manually cut off as much as possible (maybe touch a tip with peroxide to the pieces I cannot remove then rinse and return to tank) I have had bad luck with zoas nearly melting away in the past with a very mild peroxide water solution 1:4 for just 1 minute soak , so I am a bit hesitant to try the peroxide …. It was a small colony of Illuminati that melted away , like 30 polyps, super healthy and robust, colorful, etc so was really surprised
