But boy, I have a hell of a waterfall going now. 3 pumps running all the time.

I also drained about a 1/4 of it, pouring it in large buckets into my side growing area (the plants should love it), then put in about 40 gallons (still not back full) in, an 8 gallon bucket at a time after using a bit of this in each:
