I built and installed most the system I spoke about last year. Thanks Bill Cody for your help. I would have finished it but it started raining, so as it is, it is in but just one difusser. I built the header with 2 valves for each head. Mounted the heads on a creat, you will see in the pics. One patio block for weight in the creat. I mounted the pump in the garage and ran the plastic tubeing to the pond where I put the header. I was continplating if I should put a cooling fan. I ran the system to test it and didnt like how hot the pump got so I tore apart a very old microwave oven, thinking there must be a fan in it, sure enough a perfect specimin.. Anyways here are a few pics when its totally done I will post some finished pics, thanks for everyone advice.
It does give a nice boil. I would say a foot around and the boil is a inch or so high, then it throws bubbles about a 6 foot diamiter. Might be a little light for 2 heads at the same time, well see after I install the second head.
One thing made the job a PIA and I will tell anyone making there own system it can be done, relitivly cheap BUT USE weighted hose. The regular plastic is a PIA to workwith and then to sink it is even worse.
