Well, considering I only have one very small frag with eggs (I've now checked every frag in my growout tank with a magnifying glass), that isn't an option with the amount of eggs I have (there is one group, with about 8-9 eggs in it). I just now tried the drug, the problem is I only have it in pill form right now, and as fine as I could grind it up, it still did not seem to dissolve at all in the water.
My wife mentioned a sure way to kill eggs is by damaging them... grind them off with the edge of a knife or something in another container, then rinse the coral a few times then put back in your tank.
As my frag is a new addition and not one I am willing to leave in my system, away it goes.
If anyone is interested in attempting a better experiment, PM me and I can provide the drug information and some to use as well.
