Hey, I just wanted to put this out there in case anyone else is thinking about using those Micro-Pore Oxygen Diffuser's made by Deepwater Inovations. Last week I ordered a Sunleaves 600 GPH pump and a Double Micro-Pore Oxygen Diffuser from Stealth Hydro with plans to beef-up the oxygen delivery into the water of my bubbleponics 6-planter. The pump made too much noise and the amount of bubbles this combo puts out is just too much for this setup. But I really loved that Double Micro-Pore OxygenDiffuser made by Deepwater Innovations, its very well built and looks like itwill last a lifetime like they say and it's not fragile like the rock air-stones I'm constantly breaking. The bubbles this "Oxygen Diffuser" puts out are very small, 90 - 250 micron sized bubbles which are a fraction of the size air-stones put out. These diffiusers are designed for hydroponics and the air hose connection is 5/16”, not the 5/32” like you find on all aquarium pumps. They also require a lot more pressure to drive then aquarium air-stones and in my setup I cannot have noisy piston pumps that I can hear through doors.
Sunleaves makes a T-adapter for their 5/16" heavy duty air pumps thatallows it to drive up to six 5/32" aquarium-sized lines, and I thought why not flip-it and have acouple aquarium pumps with 5/32” hoses power the Micro-Pore Diffuser with the 5/16”connector. I had a Tetra Whisperaquarium pump with dual-ports that I picked up at Wallmart for $20, I picked upa second identical pump so I could some really serious aeration and for redundancyin case one pump failed. Both of thesepumps are a lot quieter then the Sunleaves 600 GPH, but if I didn’t already have this one I would have got the Tetra AP-150 or AP-300 as these are their most powerful pumps and are supposed to be a lot quieter then the Whisper30gal/60gal pumps I am using. I did not have to make any modifications to the Reservoir for the 5/16" air-line, I just removed the rubber grommet for the air-line hole on the tote and the and the 5/16” ID (7/16” OD) air hose I got at Lowes fit snuggly through this hole just perfectly.
Here are the photos of my setup:

Notice all those HUGE air-bubbles? When those bubbles break they mist the bottom of the net pots soaking the hydroton & exposed roots above the water with highly oxygenated water/nutrients. I can place my hand, palm-down, a couple inches above the water and it is damp within a few seconds from all those large bubbles popping. I was really surprized at how much "spray" this thing put out and I think this will speed up the time it takes for the roots to hit the water. I also imagine this will really help stimulate root growth & prevent problems like root-rot. I am now loading the rockwool cubes with some seeds I have been soaking for the last 12 hours so we shall see soon enough!
