S5 CO2 Diffuser Aquarium Glass Carbon Dioxide Reactor

i bought this thinking that it will help increase the surface area for my co2 system by making smaller bubbles. however, the pressure created by a DIY co2 system is not strong enough to push through the stone on top of the diffuser. if you had a co2 canister which already has pressure in it, like the ones made by fluval, then this diffuser would be ideal. howver my system doesnt. so all the air just ends up trapped in the co2 bottle. this is a great product, just not for my aquarium

PROS:

Under pressurized CO2, these are cool! The bubbles spin around the spiral, then stream out the top. My angel fish like to stare at it.

CONS:

Under low-pressure DIY bottle system, this diffuser is kind of worthless. It makes a single stream.

You need a strong tube. There's a lot of pressure built up to get this to work. I think its the spiral that requires the extra pressure.

Under high-pressure CO2 tanks, this look much nicer. The bubbles are still kind of large compared to the Fluval ceramic disk co-88 bubbles.

I've broken 2 of my 3 already. These diffusers are heavy so you need to put some airline tubing suction cups on them. Good luck. Depending on how the glass melted, there may or may not be room to slide one on.

Disappointed.

Works ok with my pressurized co2 system but had a small hole near the bottom of the spiral. This makes the spiral useless.. You get what you pay for.

OK so I got this today and hooked it up, And the spiral glass tubing on the inside has a little hole in it so that part of it doesn't work.

It puts out the bubble like it would normally but the bubble counter aspect of it is shot to death.. I'm glad it was cheap because I won't be buying another one of these, you get what you pay for...

You will need a suction cup.

Seems good so far. May eliminate need for a bubble counter.

Good luck fish people. CO2 is not a greenhouse gas.
