Thanks BB! We did another practise run, this time with the homemade p'd eggs. The egg seemed to work fine, although the pasteurizing process didn't seem to help bring up the pH any. I am still trying different brands to find ones with a higher pH, these seemed to be around 8.6 which I'm sure is way too low. The ones I got last time were around 9.1 so I guess I may be sticking with those. The SU went well, there was A LOT of sperm that made it thru the mesh and into the EW after one hour, in fact I'd say it was near 50% in each (EW and sperm).
