Hi guys,
Just wanna share information with you guys since I saw few post related to solar pump. I try a lot of DC pumps earlier this year, my goal is to run a Koi pond for aquaponics while it is powered by solar. the pump I tried are either the flow rate is too weak or it doesn't accept more than 14v - 15v current. After tried and error, I settle with 3 of the following pump

All three generated around 800 GPH flow for my 500Gallon pond.
And I did saw some of the people said use bilge pump, please don't. bilge pump is not design for run continuously. FYI
