Pond Boss Forums AERATION Systems questions Keeping Ice Off My Dock

Welcome to the forum!

I use 1/4" welding hose to feed my diffusers in the hauling tanks and I use barbed connectors. I found that if I don't use a hose clamp on the barbed fitting the hose would come off. Were you using a hose clamp on the barbed fitting?

Why did you use a 1/8" fitting instead of the 1/4" fittings?

I would take the hoses off of the manifold and check the manifold to ensure that none of the 1/8" fittings are plugged. I have seen a piece of Teflon tape plug a small fitting before. I am (maybe incorrectly) assuming that some sort of thread sealant was used on the threaded connectors? Or is there no threaded connectors?

Are the airstones the same ones that you have used previously? Have you tried swapping airstones to see if it's the airstone at that port or something else? If yoiu are using airstones and not a membrand diffuser, do you clean the airstones yearly in muratic acid?

Do you have all the fittings 100% open or are you trying to adjust them to get the same amount of flow through each one?

For every 12" of water depth there is 0.433 psi backpressure. If you don't have the hoses all exactly the same length, the airstones at exactly the same water depth, and the same air resistance in the different airstones, you cannot run them all 100% open. You have to throttle down the ones in shallower water/shorter hose.
