I dragged out the aerator, hooked it all up, and put it in the pond and got nothing. I tried it on land and had (what I thought) was good air movement.
So I pulled it all back out and made sure all was well with the line and diffusers.
I found that one of the diaphragms is shot in my Ecoplus pump. I cannot find anything on this pump telling me what model it is. It is a commercial model and I bought it 2-3 years ago. I didn't use it last year since I was doing the pond renovation and it dried out.
Anyone have a clue how I can find out the model? I found a place that has repair kits but I might just cut my own piece and see if that will work.
