<p>I used a photo plug also, but not the one mentioned. I still find it difficult to figure out the start and end points since the signal is AC coupled and not a square wave. By the way, is there any way to delete out measurements in the camera record?</p>

My old 2 bath formula uses a saturated solution of borax for B. It also had a warning that the temperature must not go below 60 degree F. Now I think we know why. I'm not sure why the borax would not re-disolve though.
