what are these?

you make it into a paste and only put it on what you want to kill.aptasia will taste it as soon as its on it and swollow some and die right away.i make it reel thick and use a syringe with no needle to squirt it over the unwanted pest.i then leave it there where it turns hard and months later it will just crumble away.it won't hurt anything it does'nt touch.i got some on a mushroom and it looked sad for a few wks.it did'nt outright kill hydroids but i completely covered them and they eventually died.i can't see it hurting anything you don't directly put it on.don't just dump it in.

ARE YOU SERIOUS MIKE?!?!?!?!?! I searched the super walmart high and low and couldnt find Pickling Lime there anywhere.. Seriously, I checked like every possible location in the store, and to no avail. Any idea if this is a seasonal item? Actually, that would make sense, it may be seasonal up here because of the short harvest period. I know they only sell the canning jars around the fall up here. You wouldnt happen to have a Pic of the packaging so I know what the hell I'm looking for?

If the aptasia are small, you can try the peppermint shrimp route, as Mike said, But I wouldnt expect to see miraculous results. I had a small outbreak of them and the peppermint shrimp took care of all but a few of the bigger ones. Lucky for me they were all on the very same edge of the very same rock. I just chiseled off that section of rock. Problem solved. I havent seen any since, until just the other day when I spotted one in the sump, and one in the overflow.
