The 4" line is correct, and a min. of 2500 gph is correct and needed. But remember, the more you flow, the larger the settlement chamber needs to be to allow enough dwell time. I like a gallon of settlement per gallon of flow. 3500 gph, 350 gallon settlement. I use discarded poly cone top Ag Tanks I turn over so after i seal the lid, the cone is now at the bottom. Most of these tanks I use are 4 foot wide, by 5 or 6 foot high, or 500 gal tanks.
