Kalk Paste

[Parnold]

Has anyone used this stuff to get rid of colonial hydroids? How do you use it, what is it and where do you find it?

Found works on aptasia but doesn't really do anything with hydroids. That was with turning off the pump and covering them in paste for about an hour.

Your LFS (if marine) probably has it.

It works awesome on aptasia:biggrin:

Best thing I have tried tbh

Try basting your Hydroids with boiling hot water.

Covering them in a gob of crazy glue works. So does a blow torch:razz::twised:
