.375 = 3/8" .125 = 1/8 .500 = 1/2 .250 = 1/4

You can unscrew pressure relief valve and take that. Then all fittigs should match that size. If necessary you can always reduce or enlarge threaded ends with bushings or bell reducers. Usually a 90 deg street elbow has male threads on one end and female threads on the other end both same size.

Thank you for all of your suggestions and input. It seems the consensus, which I agree with, is that there was too much turbulence in the water from the diffusers and a larger pump.

I went to the local hardware store and found my fittings are 1/4" I have two places on the blue manifold to add. Both have allen wrench stoppers screwed in. One at the end and one directly behind the relief valve.

I was able to pick up 1/4" nipples, elbows, Ts and ball valves. I just was not able to get a liquid filled pressure gauge at this time.

I placed the small nipple in the opening behind the relief valve, then placed the ball valve onto that with some plumbers tape. Once that was complete, leaving the diffusers set at the original settings (deep one full open, shallow one 1/4 open) I was able to open the valve about 20% and bleed off air. The end result was the large boil and top water obvious turbulence reduced to the water softly coming up and flowing outward.

I am not sure what the perfect setting will be for my size pond to have the right amount of water movement, but not too much turbulence to cloud up the water. So I'll watch and see from here.

I updated the Flickr link http://www.flickr.com/photos/mcphenius/sets/72157628235306689/ with photos of the ball valve attached and the water flow on the surface.

I can modify the manifold more, I just wanted to get the bleed off ball valve set up.

Thanks again!

I think your on the right track, if it does not do what you want in time keep the disc risers in mind.I would also get the lifting data from your supplier so you have an idea how much water your circulating.

Granted, plumbing fittings are generally referred to in fractional sizes, 1/8, 1/4, 3/8 etc, but honestly, the Home Depot guy couldn't arrive at 3/8ths, when you provided the decimal equivalent of .375??

I want to be surprised by that, but sadly, I am not.

sprkplug, you'd be suprised at how many people can't read a ruler or tape measure.
