Identifying algae growth from frag

[JacobPresta]

Hi every I bought this purplemushroom frag from my LFS about a month and a half ago and since the last week or so there has been a crazy amount of algae growth (mostly on the frag). I do change my water every week and a half and do top ups every 3 days or so, there is algae growth on the live rock but nothing compared to the piece of the frag.

Briopsis algae, nuisance. I'd use H2O2 in a syrenge and squirt small amounts (1-2 ml) in the base to kill it if you can't remove the plug and give it a 2 minute dip in 5 parts aquarium water to 1 part H2O2.

ll dipping it harm the mushroom coral on the frag?

Thank you Timfish, I will try to take it out tomorrow and do the dip but will it have any effects on the mushroom coral?
