we have a whitewater regenerative blower #WW80 3/4 horse. We have 3179 gallons of water used in about 42 tanks from 225 gallons down to 20 gallon tanks. We are trying to construct a pvc operation from the blower to the individual tanks by.....the outlet from the blower is 1 1/4 " and we will reduce down to 3/4" pvc going to 7 lines of tanks. Each tank will have at least one adjustable aerator hose going to each tank (if not 2 on bigger tanks). What are your thoughts on enough air?????Have a wonderful Thanksgiving! Mary
