Zoa help!!!!

[jbird0420]

Please see attached pic. My green zoa rock has a brown like fungus or algae problem. I don't know what it is, but I have lost some nice zoa colonies and frags in the past, due to this.

I do have a small algae outbreak right now. I'm in the process of changing out my ro/di filters.

Is it algae killing the zoa colony or something else??

Thanks for the help.

-how long have they been in the tank?
-how long have they been closed?
-Post paramaters
-Do you run gfo or any phosphate reducer?
-Definitely check the tds on your ro/di

-how long have they been closed? About 2 weeks
-Post paramaters- params are good
-Do you run gfo or any phosphate reducer? Yes and change both reactors 1x month
-Definitely check the tds on your ro/di. Checking TDS now..

two weeks seems like a long time. maybe try a freshwater dip and check your ammonia. the phosphates will probly say zero because of the algae but the ammonia might be spiked

it's in a mixed tank of corals. The other corals are fine. Ill will try the freshwater dip... How long do I leave it in the freshwater for??

-put them in the freshwater for about a minute facing up
-after a minute swoosh them around vigorously for about a minute then place them back in. if you have any iodine (saltwater supplement) put a pinch of that in the freshwater.

Thanks for the help! What exactly does the dip do for them?

-put them in the freshwater for about a minute facing up
-after a minute swoosh them around vigorously for about a minute then place them back in. if you have any iodine (saltwater supplement) put a pinch of that in the freshwater.

the dip is for zoanthids only. the hyposalinity kills off most pests and parasites but is harmless for the zoanthids for a short period...hence the 1-2 minute treatment. the iodine is just a catalyst to speed up and enhance the chance of killing off everything you don't want
