I too vote for something like 1/2" cpvc with holes in it. What I'd do is test first with a hole every 12". See if all the holes are uniformly letting air out/up. Then I'd begin drilling every other foot, test, see the effect and when you have enough holes giving your vision, stop drilling holes! I'd use a very small drill bit.My soaker hose aeration idea didn't work...
if he has the bubble bar in the pond proper and any light gets to it, you know algae is going to grow on and into each hole, hence why I advised caution so his design includes periodic cleaning (doing it easily). I dare say, even if covered by rock, I'd bet he'd get some clogging, esp if the holes are small.I have the 45 nitto it's pretty strong and from what i thought i saw the hose was under the gravel so algae is not a concern but gravel falling in the holes could be but like the bog place the holes downward . AND if you can find a sealed or make a sealed container and pump the air below water so this container so the air is cleaned and wont block up the holes. Think i might have to build my own version here
My aerator clogs up pretty quickly with algae growth, so I didn't have much hope for the soaker hose idea. I would love to find a way to do a ring of bubbles all the way around the pond bottom, but I think any thing you did (unless it had seen real force behind it) would eventually clog. Fun idea though! And thanks for trying it so I don't have to!
we've been TRYIN', @Laaf , we've been TRYIN'!!! Not only is CW a thinker he's also a tinker, a researcher, a doer with at least 3 options going at the same time! Ya gotta admire his passion for working the system but you're sooooooooooo right--get 'er done and THEN tweak as necessary. I know, I know, SOME of the plans like this currrent aeration thang might need to be buried as it goes but there's other options for covering and a lot of UW stuff is going to get covered with green anyhow, so a lot of this is just wasting time and money. I thought my stacked stone bog wall would look like X but it turned out to look like Y and it still works, conceptually, just not as visually.Your pond looks amazing............and it will look even more amazing when it is up and running with fish and plants. You are spending extremely long hours trying to engineer things that are commercially already available with even more hours of research and development than you will ever have to put into redesigning a better mousetrap. I do understand the thrill of designing and building something yourself. But the details you are working on are leaving your beautiful pond unused for its true purpose. I daresay just buy a commercially available aerator, and move on to the next step of completing your pond. Even once it is fully up and running..............that is when some of the major tinkering and adjusting begins. So you will still have plenty of details to work on. The sooner you get your liner covered so it is not exposed to the sun, the longer it will last. Think of the fish looking for a wonderful home that could come live with you as soon as your pond is fish ready. A pond is never "done" since it always needs little (or big) adjustments over time. But yours is not getting the chance to really start being a fully functioning pond because you are trying to get it "perfect" before you get it actually running. Just get it good enough........and then continue your adjustments and improvements. I say all of this with caring and encouragement. Your pond is so beyond anything I am capable of doing on my own! The perfect is the enemy of the good enough. If you are truly enjoying your long multistep process, ignore my comments. I was just motivated to write after the hours you put into your home made aerator when you could have just bought one that had years of research and development and is under warranty. I absolutely look forward to seeing your beautiful pond up and running!!
CW, just a word of caution; it's not the best idea to have water near the house, for obvious reasons, so might want to rethink actually pouring water in such a vicinity. The idea is pretty cool, but even though I LIKE such dreaming, I'm also more a pragmatist than revolutionary, esp since any 'fixes' will be on my time and my dime!Speaking of tinkering and distraction, I've already been day dreaming about what sort of water feature to add to the front yard. I think I'm going to cut a window into our basement so that we can get more sunlight in the family room and then dig out a big window well for it and make it a pondless waterfall so that I can sit in my basement and look at a waterfall.
Gonna try not to get started on that before the pond is done, though...
