I have been noticing/trying things during my last few fragging expeditions, especially with toadstool leathers. It started when I was trying to figure out why some were attaching and some were not. I have been using the donut method for all of them, but in the beginning I was not very conscious of how I was cutting them, i.e. was the cut perfectly vertical or was it lateral to some degree.
I started noticing that when the cut was skewed so that it was exposed on the bottom that the attachment most times was good within 10 days. I have a few where the cut is exposed on the top side and after 6 weeks they still have not attached. The last couple of times I have been trying varying degrees of lateral cuts with some having the angle facing the top and some facing the underside. Almost always the ones with bottom facing cuts have attached within 2 weeks, and almost always the ones with top facing cuts took 4 weeks or longer.
There didn't seem to be any difference in the health of the coral with the exception that the frags growth rates and polyp extension increased tremendously once they were attached.
For reference all frags were housed in the same 600G vat with very little difference in other parameters so I am pretty sure, even though this is completely empirical, it seemed to make a pretty big difference.
Anyone else seen this or something different.
