So the pump in my 160 gallon turtle pond went tits up last night, water quality went bad fast, i lost most of my large goldfish, koi, plecos, and assorted other fish. Anyonehavea old pond pump 500gph or higher? And as a heads up dont buy lowes pond pumps, less than 6 months on it.
Check out the Laguna max flow pumps, they make great pond pumps as they can handle decent sized solids. If you are not pumping up hill at all go with the max flow 600, if you have a 3-4 foot head height, get the 900. You'll have to find them online, but they really are great pumps. Pretty energy efficient too.
