comments = """Active Aqua 250 GPH, or maybe the 160 is enough?  Or maybe
the 40?  I like that they publish GPH vs lift height curves, and it
falls off pretty rapidly for the smaller pumps.

The 160 GPH and 250 GPH both use 1/2 inch tubing, so i'll try one of
those, easy to switch to the other one if the first one's no good."""
