Help with hydroids

[dc_909]

Is there a way to remove hydroids from my liverock W/OUT removing the rock from the tank?


If anyone knows of previously posted threads about this, could you please post?



Thanks

Try kalk paste or pickling lime paste and squirt it over them with a syringe

For me, those are hard to get rid of - I use kalk paste, but they return sometimes in the same place and other times in a new spot. I don't worry too much about them though.
