I've been following Bright Agrotech videos and I like his advice. It seems to be extremely well-researched and also backed by many years of experience. He recommends running systems under pressure, possibly using timers.
So, I know of 3 ways ebb 'n flow, or flood and drain can be done using pressure:
1) Overwhelm a small/slow drain with a pump running periodically on a timer.
2) Bell Siphon that overwhelms the inflow with a large drain, no timer necessary.
3) Flout that overwhelms the inflow with a large drain, no timer necessary.
Are these descriptions correct?
Is there another common and/or easy scheme to implement ebb 'n' flow with pressurized delivery (and/or timers)?
Do most people run their siphon or flout systems 24/7 or do they turn pumps off overnight?
Ideally, I'd like to run the pump(s) continuously for longevity but I suppose it is not necessary.
I am considering flout based design at the moment but I want to make sure I understand all the common/good options.
Amazon has it. I take it that the Meiner does not contain copper.
You might check your garden supply/hardware store like Home Depot for "Melner 4-Zone Watering System" It should be known that a lot of low cost home watering system valves have copper (or worse) internal parts so should be avoided for the sake of fish and our favorite microbes.
