1.5 acre Narrow Rectangular pond - 03/05/20 07:19 PM
I'm looking into putting an aeration system (diy) in my pond. The pond is about 1.6 acres (510ft x 210ft). According to previous owner, it's not very deep- mostly 5-6 ft? with the deepest being 10 ft??, though I have yet to really check for myself.
I've lived at this house for 2 summers. First summer had duckweed or watermeal cover the entire surface. This past summer, no duckweed, however had 100% coverage of filamentous algae. Believe to have muck underneath.
I have existing aerator setup, however think it is insufficient. Pump is a rocking piston pump, 3.4 cfm I think. There are 2 diffusers, but probably need to be cleaned off. It does not seem to put out much air, at least out of the diffuser further away.
I'm looking to upgrade. One company I checked with recommended a system using a 3/4hp rocking piston pump, 5.8 cfm and 4x diffusers (with 4x 6" membrane diffuser sticks each) and 5/8". Seems like overkill based on many recommendations I am seeing here, but perhaps the long rectangle shape contributes to this.
I'm looking at doing a diy system for cost savings. I'm starting to lean towards the Gast rotary vane pump 0523 (4.8 cfm) based off of recommendations I'm seeing from Bill Cody. Would that pump be sufficient for 4x diffusers? I've been thinking about using diffuser similar below

Also, would I be able to get by with 1/2" air line? One of the runs is 375' from where the pump would be. So that leads me to another thing is weighted, or non weighted line. I thought about non weighted and zip tying Bricks every few feet as necessary, but also saw where that my wear a hole in the line. I've also seen the trick of putting rebar, sand, etc inside another tube and zip tying it to the tubing. Any other suggestions, or should I just not be so cheap in this area.
Whew. Hopefully you guys can help me out. I'm about overwhelmed from all the info I've been researching, while also trying to build a DIY system.
