COol looking co2 "atomizer"

Wasting my day away and ran across this on ebay

yeah i saw those a few weeks ago, i think that they have it plumbed backwards on that illustration though. i would guess that the water would go into it on the same side as the co2 port. reverse osmosis huh? i thought it was just a sintered airstone in an inline fitting but i may be wrong

I like the idea of a more compact reactor type setup.

[Totenkampf]

if it works it would be, i bet it would work fine for a small setup. being small means there is less turbulence and so i would think that it would be harder to get all the bubbles to dissolve. thats why i was asking about the impellor driven CO2 reactor yesterday after i saw this:

whoa.... for that price I would just buy a good needlewheel skimmer pump and make your own. that thing is ugly and expensive.

[Totenkampf]

you think thats what they are doing? i was looking at a fractionating impellor pump (like used in a protein skimmer maybe thats they same thing you are talking about) but the one i saw had bad reviews. it looks like the impellor is just jammed up into the flow tube of a fliter housing. i know i have seen that housing somewhere before but cant recall. if i could find a suitable filter housing i probable would make one. the pH probe holder for 30 bucks is silly too, 10 bucks in parts maybe

The one linked is just a water filter housing with a small mini-jet submersible pump installed inside. I'm guessing it breaks up the co2 there and being housed in the big housing it gives even more time for the co2 to dissolve within it.

[Totenkampf]

water filter housing like on a home system? maybe i saw those at home depot?

[eklikewhoa]

Yeah that's all that is.

[Totenkampf]

hmm i wonder if they come with a center dip tube or would i have to rig one up, have to go check that out

[eklikewhoa]

Most of what's pictured in the link is rigged from what I see.

i am going to make this happen (eventually). after some research, i have found that the needlewheel pump with a "mesh mod" impeller is very efficient by itself...especially if you use a rejuvenating venturi style pump. or you can put an atomic inline CO2 diffuser (i think by reverse osmosis they mean reverse diffusion...it is getting good reviews btw) up stream of the pump instead of using rejuvenating venturi. that would be a pretty tidy system. some even run an aquamedic reactor downstream of this and report NO bubbles or mist in the tank at all, where without it there was a very fine mist. the RV setup inside of a water filter housing could be adapted so that the pump created tons of turbulence but not an over-increase of flow, as long as you dont pipe the output of the pump to a dip tube rigged into the filter cavity and maybe just point the output so it shoots around the sides of the cannister like a vortex. i think i will add some bioballs above the pump for the ultimate reactor! and then i will hook it up to a lightning rod...

I've seen these before but have never bothered to try them. I will just stick to the normal glass ceramic diffuser.

[eklikewhoa]

I prefer the pollen glass over a reactors too but this little thing is pretty neat and would really work for cheap set ups with minimal hardware inside the tank.

dude i saw that too... but it doesnt look like it will work... b/c the bubbles will eventually build to large and exit the out flow... thats why i got the hexa cuz there is actually a impellor the breaks down the co2... i will test it tmw... =DD
