We were at 2.5 acres, now at about 2.3 acres. 35% is around 7 feet deep and the rest is 12-13 feet deep, steep slope from shallow to deep. We have 6- 8 inch and one 12-inch Clean-flo diffusers. We haven't contacted Clean-flo yet to get a better idea of equipment needs from their aspect, but assume that, other than maybe needing one other larger diffuser, that our equipment should be adequate because it was before. Of course the diffusers are older and may need cleaning or replacing.
