OK, one last question for now:

Since I was using my regular 1-HP pump at about 12-15 hours per day, what should I run this new configuration on low speed?
I'm hearing that if it will pump ~60 GPM at full speed, it will still do ~20-30 GPM at low speed, but uses way less electricity to pump at the low speed. So I'm supposed to be able to run twice as long on low as I did on high and still save money. Is this a true statement or is it more marketing? Also I've read reports both ways that it increases the efficiency of your filter since the velocity of the water is so much slower that the filter will work better.

Thanks.
