These are a really solid and reasonably priced alternatives to those expensive return pumps. I use this particular model for water changes, makes them go super easy and no messy clean up after. Attach the pump to your python water changer Pop the pump into the tanka and drain in a few min. Then put the pump into your water holding tank or sink to re-fill. Can also be used in sumps are a return pump for smaller tanks. Super quiet and minimal power consumption.
