bought a bunch of those glass ladders a while ago overseas at the recommandation of the store owner, who seem to think they are the most efficient (he uses this design only in his co2 flower tanks) .

anyway i wasnt paying attention and now cant figure out how to install it. See picture: it has 1 opening on the right side and 2 openings on the left side. Which opening do i hook my co2 cable to? thanks!!

Hmm, my guess is to stick the CO2 line on the center stem on the left. The gas I think is suppose to diffuse as it courses throught the spirals, and gets in contact with water at the bottom (right) end of the diffuser.

That is a funky diffuser, I wonder how well it works. You might be better off using the standard ceramic disk diffuser.

why they put another opening on the right side then? It's kinda tough to fit the co2 tube on there, so i want to make sure it's the right opening before put it in

geez...sounds like that first time with this girl in college...nevermind

nice mental image :P

IMO just use the diffuser. The spiral looks like it can break any moment

My guess is the opening on the right side of the picture...aka the bottom of the diffuser is there tp suck in water as the CO2 bubble courses through. This ensures the gas has direct contact with water.

I would like to see this spiral thingy as it works. It really does look interesting, and this functionality mystery has me intrigued.

I'm guessing that this is a countercurrent type of thing where you have to run water through it as well (small pump or filter outlet?) The CO2 would go up the middle and be forced down the spiral by the water- the diffusion occurs when the gas tries to float back up the spiral against the water current.

Looks more like something I used in chem lab than a diffuser!

Coolest looking diffuser ever. Now I wonder how well it works.

I really wish I could do pic manipulation like that, my theory is different. I hope I can explain this so it's clear the way I think it would work, in principle rather like an undergravel filter.
Turn Werner's pic upside down. I agree the CO2 enters at the top of the straight tube. When the bubbles get to the bottom "U" , they would naturally make the U-turn and head upwards through the spiral. The gas travelling upwards will create an upwards current, pulling new water in through the short extension at the bottom of the "U" , and the bubbles should have enough contact with water through all that spiral to be absorbed (adsorbed?) before the top of the spiral.

I hope that makes sense!

To me, as soon as I equated the principle to a UG filter uplift tube, that's when my theory came to me and seemed to be correct.

I won't be surprised if I'm wrong, but I'm now really curious to see how it actually works, and if I'm correct.

(Edit. If I owned that, I just know I would break it!)

lol, this thing looks so cool with the bubble going round and round!! it actually works too. Although the bubble isnt absorbed completely, it's about 20% of the original size by the time it leaves the ladder. I should have gotten the version that's twice as long, i bet that would absorbed everything 100%.

see a quick video below, when i have some time tomorrow going to hook the exit of ladder to a normal ceramic diffuser.
