Alright-anyone still here?
Important notes:
1. For some reason if the air outlets point up this doesn't work nearly as well, no idea why and don't really care. Tried it to see if it would work better but negative, besides its easier to point them down anyways.
2. Tube length- i didn't try a whole lot of ranges, just long and what you see. However, from this I would keep it between 8-18". Shorter and you get a ton of turbulence keeping the waste from settling easily, longer and you lose lift. (Geek warning: skip this if you don't care-ideal air flow creates lots of small bubbles churning of the water, as the air rises and water pressure decreases the bubbles expand allowing the water to slide around it losing effective lift. i found this out on some various websites, and later you will see the big + to this.)
3. Where the tube goes into the bottle, make sure to push it up some. You don't want it to touch the top but if you barely insert it you just make a vortex. again it will work but not nearly as well.
4. MOST IMPORTANT! Spread out the holes on the bottom of the bottle! You have to disperse the air over a relatively larger area. If you only do one hole, like the coke bottle trial, some debris will settle into the nylon but the bubbles will still drag a decent amount with them right out the hole and into the water. Basically flings ---- all over the place. I used a push pin focusing more on the side opposite of the lift tube.
You want to get just enough so that a small pocket forms before the air escapes. This ensures that the water, carrying with it waste/debris, must go thru the nylon. (Note as the "filter bag" becomes clogged this air pocket will shrink. vac will still suction but some debris will escape.) I recc placing a few holes around the edges and running the vac, poking until you get a good pocket. Enough for now but will come back to this sometime.
I cannot explain how well this is working! I still may try to get video, but if nothing else some pics of what i was able to clean out.
Alright gonna take another break but stay tuned for the good stuff!
BA things about this vac and
REASONS I WILL NEVER USE A SIPHON VAC AGAIN!
