Since Povidone Iodine from the local drug store doesnt come with instructions for use when dipping corals I thought I'd go ahead and repost this from another thread on instructions for use.
I just mix it with saltwater according to coral type. Immerse the corals in the dip, and agitate periodically with a turkey baster. Inspect for pests and their eggs. You may find redbugs, acro eating flatworms, red planaria, monti eating nudibranchs, zoanthid eating nudibranchs, zoanthid spiders, and others.
The pests may be stunned enough to be blown off the coral, but not necessarily killed also.
After dipping, rinse and quarantine the coral.
Basic guide for dosage and timing...
Acros
3ml/liter 25 min
Montis
2ml/liter 10-15 min
Zoas
3-4ml/liter 25 min
LPS
3ml/liter 25 min
Softies
3ml/liter 25 min
Some corals have tolerated up to 2ml dip per 8oz saltwater for 25 minutes. Montis may lose color at this concentration of dip though. 2ml/8oz should be the strongest concentration to use if you are experimenting. Iodine levels peak at approximately this dosage rate, and will actually decrease as you add more of the dip.
There you go!
Please chime in!
