Uv sterilizer & pump

[ek]

Hi! For a 150gl tank with a 40w Uv sterilizer what’s the flow rate for the pump.

Please help me with this question. Thanks

EK,
Around 700gph would be my guess. Ask the manufacturer what flow rate gives you a 60,000 µw/cm2 exposure on that 40watt, 'cause your goal is the 60K exposure without turning the volume of your tank more than 6/7 times an hour.
Curious to know what the manufacturer says (and which one it is).

Thanks, they suggest mag 500gph
