You don't need airstones to "oxygenate" water...WHAT YOU NEED IS LOTS OF WATER SURFACE MOVEMENT...so a high flowing pump where the water sprout is level to the water surface is enough to move the surface of the water constantly...or you can use a DIY sprinkler...

Put a bit smaller sized tube on the output side. That will enhance the ventury effect even more. One and a half inch in length will do. Because of the smaller diameter, the water will have to go faster, and therefore, it will draw in even more air.

Good question, the only thing I can tell you is that I have perfect aeration using this system which is a dissolved oxygen level of 8. I have some systems that are 800 gallons and I run a 40 watt 620 gallon per hour pump with one 3/4” venturi. I have perfect aeration with the benefit of circulation, and it’s really cheap and virtually maintenance free. If you are running a small reservoir get an air stone. If you have a larger system, airstones get really expensive and are more of a hassle. So it really depends!

@davidstick9207

2 ай бұрын

Aeration is not about gas transfer from the bubbles...no matter how small they are. There simply is not enough time for gaseous transfer. Aeration occurs at the surface...and to get that...all you need is agitation. "Small bubbles" agitate the surface more effectively. But if the tank is deep...a small pore airstone has too much pressure on it to work effectively. Hope that helps

have you found that the venturi works better, if you only insert the top angled tube , 1/2 way in the tee..or 3/4 into the tee..or is it best to just only leave a small gap like you did in this video ? I was trying to think of a way to use your idea and somehow connect it to a cordless battery powered 18 volt leaf blower , and attach a 20 volt solar panel to the leaf blower, so it would aerate my pond during the day and maybe keep the algae from growing.

I learned about venturis in the Navy , the use them for all kinds of things, but yes it’s nothing new, but compared to air stones it’s cheaper and easier in this application.

I have been using a venturi to oxygenate my 1000L fish tank for years. Works great as long as the racoons don't get into it.

Damn chipmunks 😂. Good work, though. Thanks for sharing.

Why you don't buy a venturi injectors in the market

@SaludaGradeFarm

They’re not as good, most of them are used to inject nutrients into the solution, rather than increase air. I’ve bought them before and they do not compare to these.

You could use a rat tail file.

I have 3 of them, the aeration I get from the diy one and the pre fab one is not comparable at all. The Venturi tee are more for adding liquids to the mix then anything else.

doesn't really give you the microbubbles that are desired.

Testing DIY Venturi with Dissolved oxygen meter! kzread.info/dash/bejne/ZquOsNejpbmyY5M.html It does everything I need it to do without shelling out big bucks for a nano bubbler.

Easier and faster way: Drill a hole on to the pipe and place a small air hose. Size of the hole should be same size of the air hose

I did do water fall in my nft system, but it’s harder to keep the light out, so it grows algae. This system is under the floats, and is incredibly easy to setup in my opinion.

You aren't 'oxygenating' the nutrient, you are moving it around, nothing more. If you were oxygenating the solution the bubbles wouldn't rise to the surface before bursting, they would dissolve. When you realise what you are doing is moving the solution it all becomes so much simpler

The bubbles cause what’s is called “subsurface aeration” basically the larger the surface area and the longer the surface are is in contact the more aeration. Please see my latest video where I demonstrate that my system is perfectly aerated using this system. Max dissolved oxygen in water is only around 8ppm (using atmospheric air to aerate and not pure oxygen) so very little gas exchange is needed to create this level of dissolved oxygen.

@@SaludaGradeFarm subsurface aeration is just moving the water around, you can make the bubbles as small as you like, they're not being absorbed by the solution

This reduces the rate of flow and will shorten the lifespan of your pump.

This setup is for a large (5000 gallon) hydroponic system and it’s not visible at all, unlike a fish tank. Unfortunately this video has been pushed to all you fish people 😂 but yes if you were to have a massive tank this would be a much better alternative to air stones. ✌️

All that work for video and zero clarity of symmetrical tee and water flow direction. How about a big red arrow?!

Open end of the beveled pipe goes towards the open end of the tee. If you reverse it the water shoots up the air intake, I’ve done this before 😂 hope this helps, if you have anymore questions please let me know!
