Hello friends:
I wonder if anyone has this set-up: A sieve prefilter in front of a pressure filter?
I love my pressure filters and I also want to get sieve prefilters to remove koi poop. Since the water has to be pressed into the pressure filter I must raise the sieve filter so that there will be enough gravitational force to press the water though the pressure filter. I wonder how much higher the sieve must be?
Thanks for your thoughts!
