Hey guys ... I built this system a few years ago but after re reading a bunch of the forums I think I could tweet my system a bit .. my pond is 1 surface acres.. I would say .75 acre of that is the main pool and is 12 ft deep the other .15 is a tapering cover and the last .10 is a sandbar point ... I calculated roughly 3,296,619 gal and shooting for turning over 2X a day or 7,235,233 gal.
right now I have a cast 0523.. I have 1/2 pex going 275' to a manifold by pond.. I have 100' of 5/8 weighted line going to 2 vertex 9 discs
( I also have a shallow 3' deep vertex I switch to at the manifold in the winter that's 20' of 3/4 pex under water)
im coming up with about 8# psi I should have that being for the depth and the two diffusers.. but my gauge at pump is reading 12# of back pressure and I think its creating the pump to get hotter than it should.. I think these gases are rated to 10 psi.
problems
1. I think I need to change the 1/2 pex from pump to manifold to hopefully drop back pressure a few pounds.
2. I think with my setup and the size shape of pond I should run another 9" vertex off manifold towards the other end of the pond since the main double is off center of the main pool right now and away from the shallower cove..
it gets super hot here in the summer in western Illinois and I plan on turning over 2x per day so in the summer I can have my home automation turn the thing off when outside temps get over a certain temp or just at night... is this a good idea if so what would be ideal outside air temp to turn off at..
I have HSB stocked and this pond is low with little airflow I have sonar holding duckweed at bay but hope to correct pond with aeration and bacteria...
Is there anything else you could see could use improvement or other ideas or critiques?
Thanks everyone!
