Glass CO2 diffuser design, any impact?

[chingkt]

Saw there are lots of shape and size for glass co2 diffuser. Some of them look simple while some look long, big and complicated. Just wonder does the design has any impact to co2 diffusing? Or is it only for the look?

In my opinion, no impact, the one that matter is how fine the buble coming out from it.

Some of them are look complicated and can be use as bubble counter as well.

Is it true the bigger and more spiral type of glassware diffuser will diffuse CO2 better into the water?

A bigger diffusion area is important. The clear glass part is mainly for looks only and that is a matter of preference.

The spiral types act like a bubble counter and is built mainly for asthetic reasons as well.

Bigger surface area mean more bubble coming out, thus more CO2 mixed in water. Other may say that number of bubble coming out depend on the pressure . Can't comment which one correct

More spiral mean easier for you to count the bubble

The spiral increase the time the CO2 stays in water. The lower the angle of the spiral, the more time the bubble takes to reach the time, thus more time to diffuse the CO2 into water. But however, cause the bubbles is rather huge during the spiral stage, not much diffusion will be taking place. Mainly the diffusion is at the ceramic area.

Is this the reason why an ADA pollen diffuser costs an arm and a leg while a Taiwan/China/local-made diffuser costs $6-$9? I notice cheap diffusers produce large and small (non-even size) bubbles. Is this due to quality?

I do not see the point why want to increase the time CO2 in the water inside the diffuser? The water inside the diffuser never mix with tank water.

Actually it does diffuse abit, but not enough to supply the plants. Rather than design the tube area into a vertical tube, in which the bubble with just go straight up and diffuse in the ceramic area. Having the spiral add abit more of the diffusion, but not really much. Which is consider very very little. But better than going straight up, better than nothing. The spiral can act as a bubble counter too.

is a DIY co2 system able to be strong enough to get the co2 out of a small diffusor?
my DIY without any diffusor can produce abt 5-8 bps at the moment.
thnks for advice.

it is for short periode of time, for DIY CO2 I prefered using fliper

i agree with you.
i am seeing a fine flow of bubbles via my diffusor today with my new preparation, but i envisage it will be more difficult to push the gas through the ceramic when the co2 mixture is older, perhaps max is 2 weeks.
but i am prepared to change it every 2 weeks.
since my tank is only 1 ft big, a co2 cylinder may look awkward next to it.
btw, how does the flipper work?
how does it look like?
thnks

Quite interesting to see the bubble getting smaller and smaller when it is on the way up. by the way, it is not my photo, I just link it here

[Aquaria One]

There are some that the BuBBles don;t Break up into smaller BuBBles those aren't co2 effcient and is just like BuBBling the co2 like a air pump

[mikmik]

Will the CO2 diffusion or bubble size be any different if it is placed either in the middle or lower portion of the tank as the water pressure will be somewhat different?

[Shadow]

in some degree maybe, but never try to test it out. usually what you want to do is to make sure the bubble stay in the water as long as it can. Thus put it at the most bottom of the tank.
