Purchased our house in the summer of 2017. Has a .41 acre pond with existing aeration. Slopes fairly quickly with max depth of 7-8'. Pump is a Hi-Blow HP80 with about 150' total of 1/2" line currently with a 9" stone diffuser. (100' poly in ground, 50' weighted in water) Pond is a fairly perfect oval. Always have ran it 24/7 spring through fall, then pull it to shallow water and run occasionally during winter.

I THINK to get pressure I calculate .433psi per foot? Puts me around 3psi? If correct, I'm flowing 2CFM based on the chart?
Calculations correct? Decent flow for size of pond? Considered upgrading to a better diffuser, worth it?
