had an extra pump laying around so i had an idea. Hooked it up to the Python and man am I glad i did. make w/c about 4 times faster.
I have no idea what the gph is on that pump, but I did a w/c without it last week. Siphon only, no faucet adapter. It took about 40 minutes to drain 50% of a 100g. with the pump on the same 100g it takes about 10. Have to be careful though. Extra flow means extra vacuum. I wouldn't suggest doing a gravel vac with it. It will suck the gravel up.
