Lolz your smoked no way!!
So my 80 gal compressor that holds 200+psi in my garage is a "bomb waiting to happen"? Or my oxy/acetylene or my argon that could have thousands of psi in them? There are reasons these tanks get certified. Make sure your tanks are in cert. , keep caps on tanks that aren't in use, put a safety chain to the wall so it can't fall over..no problems.
I don't have a pic besides this one on this page after I put it together. >>http://rollitup.org/t/has-anyone-used-a-ait-air-injection-technology-the-spider-airstone.848740/page-2
Your compressor is not pure oxygen, its air, just air. And your oxygen/acetylene tank is not dumping pure oxygen into a room, its burning it so not what Im refering to. And argon is an inert gas so it'll just kill you if it displaces the air your breathing. I weld to lol. But I dont dump pure oxygen into my room as that is a bad ideal imo, but hey each to his own.
I can only find that hosing sold by a company called aeroflo. You have to spend at least $150 and buy 100ft of it because it's pond hosing. But I might have found something cheaper & easier. You know those lens cleaning cloths that are kind of shiny and feel smooth as silk? Take a cottage cheese / small butter plastic container, cut a hole in the lid and leave about 3/4" of the actual lid piece so it snaps on the container with a open top. Take the cloth and wrap it around the top, then put the lid on over top, run some hot glue around it to hold in place, should of told ya to fill plastic dish with marbles hallway to weigh it down. Poke or drill a small hole somewhere along the bottom edge a little smaller than your air line so your air line will fit it tight. When you turn on the pump the lens cloth acts just like a rubber micro membrane diffuser. Here check out this, its where I found it, just trying to find a material that will work like the lens cloth but is bigger that 2" square to make a nicer larger one out of a nice sturdy container. The link to the video is below.
I couldn't find the material or that porous hosing anywhere, but I did find the same type 9" AIT spider like diffuser for $11.95!!! http://www.ebay.com/itm/Hydroponics-Air-Stone-or-9-Spider-for-a-3-5-or-5-gallon-bucket-Awsome-growth/261290265903?_trksid=p2047675.c100010.m2109&_trkparms=aid=555012&algo=PW.MBE&ao=1&asc=29005&meid=a6e69749cde046039b2fb8665ae79794&pid=100010&rk=10&rkt=19&sd=111622706934
Right on man, I got the same ones
They work well, I'm not sure what my air pump is in LPM or GPH, but my pump is 34watts and I have used them with 4-6 3.5gallon buckets. Just watch for the roots, they grow so fast and tend to start growing around the air stone (pain in the ass to untangle them)
This could work, but the spider diffusers have thousands of holes, it would take some time and a steady hand I think to make one. I think the holes are fairy small, much smaller than a pin hole I think, but not positive.
Yeah that would work but it's not the same, The diffuser hosing is made of an EPMD porous material and that is how it creates such tiny .5 - 1 micron size air bubbles. I'm not positive but it seems like that wouldn't be possible using drip line hose. Even if you used a syringe the holes would still be to big. Rather than spend the time on getting that porous pond hosing, T fittings, then the time to build each one, $11.95 is cheap enough for me. Originally the ones I was looking at were $22 - $35. Plus these are set up to work perfect with my 4 outlet 7 liter per extra quiet air pump. Rather than use my commercial air pump with manifolds and crazy amounts of crappy air stones.
Depends on how I plumb my buckets. If I intake with two 1/4" spray heads I planned to use a second bucket to drain into with a micron screen in the top one. I read this drainage from the top bucket to the bottom creating a small water fall effect is good for DO & I read so are the atomizing heads. That's why I need to decide how I'm going to plumb this dam setup!!Right on man, I got the same ones
A small pump in the bottom of a DWC bucket that pushes the water to the surface works great, as does having a short length of tubing that clears the water's surface. Look up 'flooming' for a more in depth explanation.
Y is dumping pure o2 in a room not a good idea i k now it would be expensive to do but i really dont see a saftey issue unlesss u do it inproperly
