How to kill hydroids before they spread.

[ReefAddict16]

I have some colonial hydroids and they’re spreading fast. What’s the best way to get rid of these?

Kalkwasser powder *pickling lime " mixed with SW to make a paste thin enough to suck up into a syringe or turkeybaster.

Try using a Sea Hare...I have the brown Hydroids which have been a blane in my life for 18months, Tried to scrubbed off, Kalk all sorts....these guys are the only thing which are really kicking its butt!

Thanks Miles.
Ive read on other threads to try a peppermint shrimp so I added one.
Though I don’t see him out much seems like the hydroids are disappearing.

Peps are hit and miss imo... more likely to nip your corals although I had some rid some aips.... they don’t touch my hydroids or my aips anymore just my SPS... the sea hares are the only thing which I have had success with. I’ve tried peps, non reef safe starfish and a tiger Crowley...none has worked like the hares.... try them they are far more reef safe than the peps!
