What are your thoughts on this plan: 3/4 acre pond with almost perfect oval shape and max depth of 13 feet. Gast 0523 running 50 ft of 3/4 poly tubing to waters edge then stepping down to 100 feet of 5/8 weighted line to a three diffuser setup in the middle of pond. Three 9” Flexair rubber membrane diffusers. Anything you would add or change?

Only thing I would add is a manifold assembly so that each diffuser had it's own ball valve to adjust the air going to each one, a pop-off valve in case pressure gets too high for any reason and a low pressure gauge to monitor system pressure.
Where the compressor goes has to have lots of air flow to keep the temperature down where the compressor is housed. Also put a large air filter on the inlet side of the compressor. The sintered metal "filter" is not really a filter, it's just there to keep it quieter.

Actually my plan was to have the three diffusers ganged together off one single weighted line.

One other thing I am trying to figure out are the fittings required to go from the 1/4 NPT outlet on the pump to the pop off valve and pressure gauge. Also the transition from the 1/4 to the 3/4 poly and back down to the 5/8 weighted.
