I use three 4qt large bowls.
1. 2qt saltwater, 2 capfuls of Bayer x 5 minutes.
2. 1qt saltwater with 16oz of H2O2 x 5 minutes.
3. 2-3qt saltwater - to rinse before placing in frag tank or display.
I had a small red/green favia frag that bleached white in H2O2 - my fault, I was busy and I think I left it in there for 20 minutes. The color came back after 3 months and now it's plating off the frag plug.
Sometimes zoas get ****** off and won't open for 1 - 3 days. The 4 zoa frags I dipped yesterday with the above method opened up within 4 hours.
My GSP covered rock closed for 2 weeks. They're fine now.
I try to always remove the original plug. I keep a selection of plugs to use if I'm doing temporary placement.
I always inspect with a lighted loop and tweeze out anything that looks suspicious.
With the above method I've dipped:
GSP
zoanthids
Duncans
Toadstool leather
favia
micromussa lordhowensis
trachyphillia
candycane
birds nest
branching montipora
montipora digitata
montipora undata
stylophora
pocillopora
euphyllia paraancora/ancora
euphyllia paradivisa
lobophyllia........................ I, I think that's about it.
