hydriods bubble algae

[bignose]

I have a 15G nano with corals only. I have hydroids and bubble algae showing up, anyone know how to control these in a coral only tank?

If its just a 15gal replace the live rock with clean pieces then torch the hydroids and cook the old rock.

the hydriods are growing on a frag

On the actual coral or just on its mount/disk? Hydroids scare the crap out of me. I once watched a friend have to pull apart a fully stocked 225gal tank and blow torch all of his rock because they were killing everything. I'd try to cut around them and discard what they're attached to.

They are growing on the mounting disc. I will cut the disc apart it's worth trying.

emerald crab for the bubble algae

I threw a few frags out that had hydroids growing on them it not worth the hassle, as for bubble algae emeralds or manual removal.

+1 for manual removal of the bubble algae. But carefully, you do not want to break any bubbles

i havent had that much success with emeralds. However i hear its hit or miss depending on each crab. They seem to avoid the larger bubbles as well so manual removal seems to be the only sure way unfortunately :\

I'm going to cut the frag apart and save what I can. Seems like the easiest way to deal with this.
