Thanks for the info. I have the Borax but found I ran out of bleach so I took what the wife had left in the laundry room (regular clorox, about .5 gallons) and put that in there till I can get out to the store tomorrow.

Re the pump... apparently that 1.5HP (SPL) is actually about a 3/4hp in actual hp ratings. That's what I got from some people on this forum previously.
