well Doug, if you saw any of the pictures from my aptaisia problems you would know that it was incredibly easy to use, heck I could have dosed the stuff with my top off water I had so many of the buggers
At any rate, it was very simple since I did not have to inject the aptaisia but rather feed it to them. There were a couple of spts behind rocks that were a little harder to deal with but still better than any other methods that I had tried.
Lastly, I did not feel the same worry when I was working closer to my other corals since it did not affect them adversely like the injections of kalk paste were.
Overall, extremely happy!
Best,
Rob
