scrappy
i'm of the opinion that in an air lift scenario, bigger bubbles move more water than smaller ones (ie the diffuser isn't helping, plus it can rob you of a lot of your CFM)
Could be, but i also could see a wall of small bubbles being more effective than fewer large bubbles. Once we got a flow, it was time to go, so we did not try each way. i can do that in the future but my friend (where I'm working on it) has a work gig for ten days so it will be awhile untill i can work on it again.
The biggest key seemed to be the smaller diameter of the up riser. The smaller diameter seemed to allow for higher pressure, and less water for the air to push, and was enough to get some flow.
I re-read my previous post and now realise i did not mention the upgrading the pump to a commercial eco # 3, so part of it was the larger pump, but even with a bigger pump, we still had to reduce the size of up riser to get flow......scrappy
