HELP: Firework Clove Polyp Algae Growth

[dsagerman]

Hello, my firework clove polyp has shown some algae growth over the last week and I feel like more of the cloves are not coming out when the light is in, half definitely still are. I tried to lightly brush some away and put in higher flow but it’s not really making a difference. Should I do anything else or do a hydrogen peroxide dip? My others corals don’t show any sign of that. Below are recent water parameters and pictures. Thanks in advance!

9/27/25 (13.5gal Nano, pre 20% water change yesterday)
* Temp: 77.1
* Salinity: 1.025
* Alk: 173
* Nitrate: 10.2
* Phosphate: 0.20 (Have been running Phosguard to lower)
* Ca: 430
* Mag: 1350



AI Prime light settings, light is 10” above water surface.


* Ammonia: 0-0.25 (Basically 0 on API test)
* Nitrite: 0-0.25 (Basically 0 on API test)
* pH: 7.8

You need to move them away from that LPS ? Duncanopsammia. LPS sting clove polyps.

Got it thanks. I will move that away now. Any thoughts on the algae? Appreciate the help.

I would dip them in a peroxide solution of 20% (3%) peroxide and 80% tank water for 2-3 minutes. Boom! all algae will be dead. Just put it back in the tank after that.

I have done peroxide on clove polyps years ago. They survived but did not open for a few days. Usually I just toothbrush/pluck it off.
