Noel like you stands, simple and to the point, by messaging with you I know you have Vertex 9" Single Air Diffusers from Hoosier Pond Pros. Did you just buy the cheapest head and screw them to these pictured stands? Also did you use any kind of check valve to prevent water coming back in lines when pump is off? I am thinking of putting all three heads on one stand so as not to have to set up a valved manifold. It is so hot here in Missouri, as you know, that if I weren't afraid of a big fish pulling me down I would jump in my pond! LOL
