If calcium aides in floculation, would adding gypsum or calcium chloride to a starter speed up cold crashing? Any ill effects?

There would be no ill effects, but it might not help at all.  If there is already enough calcium for flocculation to occur then adding more won't help.

If it is made from DME, sufficient minerals are already present.

You are actually better off with about 10 to 20 ppm Mg in the starter water than any calcium addition. Zymurgy readers will get the full story in the Jul/Aug 2014 issue. Epsom Salt is OK.

Thanks Martin. I will give that a shot.

I have been using a lot of 3711 and 2565 lately. Some weeks I don't know if I will brew Sunday until Friday afternoon. In the past I would pitch the next morning, but I have much a earlier workday now and don't have the 10-15 minutes to aerate and pitch before I head out the door.
