Potassium permanganate dips

[sl-atl]

If you are using a Potassium permanganate dip to kill montipora eating nudibranchs and their eggs, what concentration and especially duration are you using?

I got a 50mg/L concentration from this article (http://reefkeeping.com/issues/2007-09/eb/index.php) and some other posts. Not to sure about a safe duration.

This seems to be the best or only way to kill the eggs... I got burned once by this things- killed both my Monti caps...

It's hard on the coral, I've never lost one but you definately know it's been treated.

50mg/L is correct. 50 mg is a tiny amount and needs to be measured accurately.

I did 45 minutes the first time. The second time I forgot about my corals and they were in there about 1.5 hours. They all survived, and I am nudi free.

They are brown after the dip, but within a few days the color comes back.
