I need help finding out what pump i need in my sump tank
What size pump to use in my sump tank?
I have built my own tank - originally I had a Fluval Fx5 External filter 1500ltrs but because water level in sump is lower than the top of filter, filter was constantly sucking in air and stopped working. So I need to replace with a sump pump.
Main Tank = 191 UK gallon - 193cm long, 140cm height from top of tank to floor. 67cm deep single flow in 1 1/2 inch pipe inlet and two return pipes 5cm.
Sump tank = 59 UK gallons - 193cm long, 35cm high and 280cm water depth.
