Cocklebur - suggest you not settle for one or the other... The SolarBee solar-powered circulator can provide oxygenation down to the bottom plus control algae at the surface.

Long term cost is low compared to other solutions, units have a 25 year life expectancy with minimal maintenance, and are silent from 50' away.

We have a rental program as well, so you can "try before you buy". See our website at www.SolarBee.com for an online video and other information.

Best Regards,
