Silicone Membrane Diffuser Tubes

anybody ever use these? they look wicked compared to others i have seen. looks like way more output with smaller bubbles. im gonna start a recirculating dwc 6 plant 18 gallon set up. these look like they would be ideal for the larger totes im going to use but i dont know anything about them. they look like they might need alot more air too. so how about it? anybody know about these silicone based diffusers? they also have some lower grade stuff that doesnt look to bad and it called silicone rubber diffusser hose pictured at the bottom. i have never heard of either.

Where do you even buy those? I only use black silicone air tubing, so now that you showed me those I must have them.

you can get the diffusers here and they are priced fairly. i just want to know how well they work. that 24 inc stick would fit perfect in the totes im going to use. looks like a hell of alot of oxygen to me. i think im going to email alita and see what they can tell me about these with hydroponic applications. make sure there arent any harmful biproducts that could harm the water and see what type of bubbles are achieved.

omg yes! i came across "microbubble" air diffusers at youTube which I couldnt find for sale anywhere. Thanks for the link, checking it out.

The performance of these is def going to rely on the pump. betting it'll make those fine amazing bubbles with a "commercial" air pump only and not an aquarium pump.

Hey guys just so you know this stuff is tricky. I talked to the guy from Alita for a couple hours and assured me my pump was sufficient and everything would be fine. I have had the tubes for a couple weeks now and tried everything to get them going. I finally talked to the Alita guy again and he told me they need to be submerged at least 3 feet to create enough water pressure to get tiny bubbles. I sure wish that would have came up in the conversation before I bought 10 feet of it. If your reservoir isn't deep enough you may end up like me, stuck with an $80 diffuser hose pumping out a few large ass bubbles using an 18w commercial air pump I am hoping all is not lost and I can use it in the compost brewer I plan on making for next year.

Water temperature is the most important factor in dialled oxygen levels... Save up for a chiller or insulated buckets !
