Parzifal Posted April 29, 2018 Share Posted April 29, 2018 Hello All! I want to build my own protein skimmer (60" tall x 12" body) and am looking for recommended books/websites to reference i order to figure out CFM air draw on venturi valves depending on pipe diameter and GPH water flow. I would appreciate any direction, most of what I have found so far is high level calculus and really only need something a little more simple than this: And on this note, anyone have any 12" diameter PVC they want to sell?

Sharklover Posted April 29, 2018 Share Posted April 29, 2018 The best I’ve seen you will find at beananimal.com. He has a 60” that he lists out all the specs for. If I remember right there are even CAD design files for download. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

wanareef Posted May 2, 2018 Share Posted May 2, 2018 I have the perfect air stone if that's the type of skimmer you'll be building. will post pix later Quote Link to comment Share on other sites More sharing options...
wanareef Posted May 3, 2018 Share Posted May 3, 2018 This is what you need for a lot of bubbles and a good strong pump to push it Quote Link to comment Share on other sites More sharing options...
Parzifal Posted May 3, 2018 Author Share Posted May 3, 2018 What the heck is that thing? Need a big Alita air pump for that! Quote Link to comment Share on other sites More sharing options...

Is ρ density? I believe that by looking at this equation that this is for fine tuning a protein skimmer or pump. Maybe calculating the density differential as you proceed up the skimmer? Which would be applicable for engineering a protein skimmer, but density, viscosity and a lot of these constants change from tank to tank. For your sake and really all of ours who just want to turn a knob to raise or lower the proteins water level. I really believe you can resort to simpler methods. I've seen people even make these things out of Gatorade bottles and they work perfectly fine. I think if I was going to design one, I would just make sure the water inlet and outlet have valves, the air pump has a valve, along with another huge valve to raise or lower water level with the ability to overflow more than you'll need. No one would want a protein that size to overflow. Quote Link to comment Share on other sites More sharing options...
