Diffuser question...

Trying to get as much input from folks as possible, I am double posting this on a couple of forums. I thought I would try the 'Barr CO2 bubble system'. I found this from a link on apd, and thought I'd try it out. Anybody have any experience with these ? They certainly are reasonably priced. I wonder how often these diffusers get clogged up.

Comments welcome. Thanks.

Those are designed for air pumps, not CO2 injection.

Better choice:

I was looking at these in my DrsFosterSmith magazine today. I'm currently using an airstone that produces small bubbles, but this sounds like it would produce even tinier. My airstone does get clogged quite frequently also...


...and how does that glass diffuser work exactly?

they diffuse the co2 into tiny bubbles aka finer mist...better co2 diffusion into water.

I think I built my inline reactor a tad too short and thus have tons of barely visible bubbles that come out of my spraybar. The plants near it have gathered some underneath and seem grow much faster than other plants in my tank.

If you already have an inline reactor, maybe you could turn it upside down so that the co2 input is closer to the return line to the tank (less dissolved this way?)

get a nice glass diffuser, much better than stone or wood diffusers

Picked up a 2" ceramic diffuser today to use with my DIY CO2. It really does put out a cloud of fine mist bubbles. Every bubble is easily smaller than 1 cubic mm.

Will let you know how it does with clogging up.

Bert I actually bought one of those Rena diffusers- they are definitely not made for co2. I bought it for my quarantine tank to run an air pump. The bubbles it produces are way to big. The glass diffuser is what you want.

Definitely do let us know! I am always for horror stories of sticky sweet goop dripping from the ceiling!

Well this isn't the Rena brand, but it's exactly the same thing. We must have different recipes for DIY or something because mine's producing ultra-fine bubbles that are much smaller than the ones I got from a regular air-stone...

Oh stop! There isn't enough pressure to make maximum use of the air-stone, the bottle's not gonna explode...

...besides, I blew through the tubing myself to see if my head would explode, and I lived to tell the tale!

I have been using the sweetwater fine stones from www.Aquaticeco.com

These are as good as the Azoo disc if not better and other disc, quite consistent also.
They cost 1.70$.
They are better than the Rena stuff.

Hard to beat.
Hardly any back pressure too.

I also used the ultra fine diffusers, the plate type that need 25psi to run them. These are super, but suitable for large tanks(55$).

Venturi designs are very good and produce the best mist really(many SW folks will attest). I have a needle wheel powerhead that is specific for venturi type skimmers and it's a super way also to add CO2 to a FW tank.

I would like to get the diffusers on all types out of the tank and blasted into the outflow of a pump/caniters, return etc.

The mist blasted around a tankl works better than any methods I've seen, and I've been playing with CO2 for a long time.

You can see the effect.
Folks can carry on about why it work all day, but the fact of the matter is that it does indeed work better.

Well I'm referring to the rena brand that Bert linked in his first post. I even tried to decrease the pressure to see if i get smaller bubbles- it didn't happen.

Tom- are the bubble size produced from the sweetwater fine stones similar to a glass diffuser?

Also are these the ceramic plates you are referring to?
They are kinda big no?

Yeah, it's interesting. They look like they're exactly the same thing with a different name slapped on them, but vey different results!

I think Tom is referring to these: http://www.aquaticeco.com/index.cfm/...ories/ssid/383

If you click on the 'Diffusers' link near the top for more information. Here's a snippet from that page "Sweetwater® diffusers are the original 2,000°F glass-bonded silica diffusers introduced by AES in 1978."

I actually ordered one of these back when I also ordered their Azoo brand ceramic diffuser (http://www.aquaticeco.com/index.cfm/.../3608/cid/4017 ). I'm still using the Azoo, so I haven't tried the Sweetwater brand yet.

I've been happy with the approach so far. But, I'm not really getting much pearling and my BBA is still there...even though my CO2 levels are consistantly >30 ppm (typically closer to 50). So, what else is missing from my tank ?

Brian.
