joe's juice works pretty good when done right.
here are the steps:
- turn off the pumps and wait for the water to stop moving (turn off the lights too to prevent overheating of the water)
- completely cover the aiptasia in joe's juice (or clone product)
- wait 15-20 minutes, letting the little pile of joe's juice disintigrate the aiptasia
- suck up the joe's juice pile (along with the little aiptasia bits) with a syringe. try to get everything
- turn pumps back on
- you'll probably never see it again
try to limit this method to 3-4 polyps every few days. joe's juice (and simliar products) will increase your specific gravity (they're salt based).
