Coral Quarantine- what am I doing wrong

[WarDog]

Stringy web and slime is normal for an upset coral. I've never dipped for that long. I just put them in for a minute or two then baste the crap out of them with a pipette. Maximum 3 or 4 minutes total, and one at a time. Perhaps your bath has too much dip? I usually do 2 rinse baths also, basting there too. Perhaps the double dip is too much? I usually do one dip in a peroxide mix, rinse, Revive dip, rinse, rinse. I've maybe lost 5% of new frags with this method. Also always inspect the used dip solutions with a flashlight for nasties.

Send me some pictures of your QT set up on instagram @canadianreefmaster
and the lighting, and filter. And maybe the water parameters.
Maybe I can give you some pointers.
