myrionema hydroids

[Ruth]

Ok so I let it soak for about 4 hours and have just done a water change (100%). Quite a few of the hydroids came off and I still have the purple mat indicating that the GSP are still there. I am going to let it soak overnight - do a water change in the morning and see where we are at. A small brittle star and a couple of small brisle worms were also floating - dead.
