Naah. No need to pay for it. grin Don't need anything industrial scale. I'll try a couple of types of DIY manifolds and pressure chambers with different pipe sizes and use what works best for my application. I'm in the process of locating a tank I can do my testing in.

Try over 200 years; was invented by Carl Emmanuel Loscher in 1797.

Yeah I knew that too...

You couldn't prove that by me. I have yet to see a fresh water recirculating system that is run on air lifts and I've seen quite a few including multimillion dollar systems. But if you say so.

I guess I'm not aware of any sea water systems in Indiana. So there aren't water pumps that are made to withstand corrosion?

Don't want to use more power; I want to use less. That's my main impetus for designing a system that runs on air lifts.

And yes diameter of the pipe is one of the parameters, but remember I don't need industrial scale power at industrial scale power consumption.

I always do. wink

Nothing in this world is one size fits all. Nothing. grin

I knew that from my waste water class in fisheries science before you were born. wink Dude really? You didn't think I knew that? It's in all the recirculating texts. shocked

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
