Water pumps for the aquaponics?

You need pump ranges above 200 LPH to use in aquaponics and this even help in the process of long run. Most water comes with a starting of 200 LPH in India, so buy it once the system is built.
200LPH Pumps can work for Aquaponics, why don't you buy one and see if that is suitable for you. In India we are getting DC pumps too that had more pressure for spraying on plants so check that DC pumps too for using solar pumps.

This is just 2 cents advice, but check with other people posts and even water pump.
