how many gph - your opinion pls
Hello, could I get some opinions on what size pump to get for a new 700 gallon pond with goldfish - either a 950 or 1200 gph?
For my old pond (175 gal.) I was advised to turn over the water around 1.5-2 times per hour so I got a 360 gph pump and it served me well - have had healthy fish and clear water for 12 yrs now.
For this new pond I would like to take the same approach -however these larger pumps require considerably more energy (watts) to run so if I could get by with less gph maybe I want to do that......?
