DIY CO2 and a diffuser

I haven't tried it with the Azoo, which BTW you can get cheaper at drsfostersmith.com or http://www.aquaticeco.com/index.cfm/fuseaction/product.detail/iid/3608/cid/2919.

aquaticeco has sweetwater diffusors that are as effective as the other diffusors. I hear it works well with DIY CO2.

I have tried DIY CO2 with aquabotanic.com glass diffusor and it worked.

Hagen Ladder

I have heard excellent things about the Hagen ladder - it is only $10 at Drs. Foster, etc. I installed mine today and by tomorrow I'll know if it is as good as it is supposed to be.

The little glass bowl above still has tiny tiny bubbles coming from it right? Are the bubbles pretty much dissolved by the time they hit the surface? Whatever is not dissolved is wasted. The bubbles in the Hagen Ladder are supposed to be totally gone by the time they reach the top.

Why spend alot of money when you can accomplish the same thing for much cheaper.

I've never used a bubble ladder, but I have heard that they are not all what they are cracked up to be, ie. the bubbles don't dissolve, but that is just what I have heard, so I could be wrong. I will have to give a diffuser a try. Right now I am using an air stone, and it just makes large bubbles.

I use that Azoo diffuser in my main tank. I bought it before I went with compressed CO2 and tried it with DIY. Needless to say the ceramic diffuser needs a whole lot of pressure to function properly and I didn't get good results with it. I recently brought it out of retirement and tried it with compressed. A different story altogether. Quite impressive really.

The hagen Ladder is definately a great choice. The glass diffuser emits tiny bubbles that dissolve before they reach the surface, similar to the hagen method of running the bubbles up the rungs of the ladder. Blowing the co2 mist bubbles around with a filter current before it gets to the surface helps dissolve the bubbles better, and get's the co2 bubbles stuck under the leaves for direct co2 diffusion into the plant leaves.

The hagen ladder does the same thing, the bubbles get really tiny about 80-90% co2 diffusion. Only bad thing about the ladder is it takes up too much space. But it is a great option for DIY CO2.

You don't have to spend a lot of money a glass diffusor. A good alternative is the sweetwater stones from www.aquaticeco.com.

I've tried a few types now and mostly use the Rena Micro Bubbler ceramic stone diffuser. I'm going to try the limewood ones next.

One I'm using in my new tank and I *really* like it is the Ebo Jäger Air Diffuser:

Man, it's on clearance -- $1.19. Gonna buy a few more. You can turn the dial to produce a *really* fine bubble and it's not as noticeable as the white stones.
