8:40 I dosed 1 ml into several spots on a large trash paly's mat. They all seem to be affected. Palys on the underside of the rocks are closed as well. I will keep monitoring and post as things change.
Cut the rock in half and throw it away. I've been there and done that. I have the brown ones covering my overflow box, looks awesome but is a disaster in the waiting. Good luck.
I assume you are turning off all of your pumps and "shooting" the vinegar at the mouth and base of the protos? I've done kalk paste in the mouth like you would Aiptasia; may require multiple treatments but that was for a limited number of polyps in the wrong place.
I have a needle and am literally injecting vinegar into the side of the polyp. The polyps I injected are completely gone, but the others around them are not affected. Seems like injecting each one is going to have to be the route. I can't destroy my agrocrete, so cutting stuff off is a non option.
Too bad it didn't spread into the mat, that would have been great. If you're going to inject each one, how long are you going to wait between treatments? You mentioned the vinegar could crash the pH. How do you determine how much to use and how often, or are you just winging it and monitoring your levels?
Will this work on other pests? Say... maybe something that looks like this...? majano.JPG
