Hairy acropora and zoa

[407Hunter]

Hello fellow reefers,

I need help with a identifying if this hairy growth on my acropora since day 1 and I ignored and now at the base which seems like algae.

The zoa has something different, has had these since day 1 (removed with tweezers) and grew back. Not sure if hydroids or aiptasia.
Both corals are new (under 2 weeks).

I'd say hydroids on the zoas but not sure about the wiry stuff on the acro.

Thanks for the fast response! I’ll try to rid them again if no help I’ll toss this Magic Zoa out as I got at an auction for $5.00.

Looks like green hair algae in the 1st pic. Manually remove.

The acro looks like it could be GHA or the start of bryopsis.

Peroxide dipping guidelines (for corals)

A while back Justin Credabel published this chart detailing the concentration of hydrogen peroxide appropriate for dipping various genera of corals. I've used these guidelines myself a few times to remove algae from coral frags and it's been quite effective. Justin Credabel's hydrogen...

Thanks! Shouldn’t do harm to scissor them I guess. Any clue about the base?

Neither sound good. But thanks! Is it late to QT these after removing that stuff?

Likely the same, hard to see.

They are they easier of problems to deal with. Once you manually remove and if your parameters are good shouldn’t be a problem. Just wait till you deal with bubble algae, aiptasia vermetid snails ect. It’s always something.

Let’s hope those are forums I won’t ever have to search for.
