External inline CO2 diffuser......which one ?!?!?

I use the first one for a year now. I love it. Only problem is that it gets junked up every now and then. Just have to wash it out. It also takes up a lot of room seeing that it takes a powerhead to run it. Seems to get a diffusion of CO2. I highly suggest it.
 
I was looking at the atomic inline diffuser from GLA, but I found a post (i'll try to find it again) which stated there might be some clarity issues with the diffusers which hook up to the return line of the filter. Basically there will be thousands of tiny bubbles released when the co2 "mist" enters the aquarium, causing viewing/clarity issues. I think I am going to go with the pollen type from ADA...

well the nice things about these is that you don't have to put the equipment in the tank. It's nice to look at the plants in your tank and not the equipment.

That's exactly why I wanna switch to an inline diffuser.....

@ rockhoe14er, aren't these two diffusers working in the same way ?!?

And do you have any viewing/clarity issues with your tank ?!?!

BTW, I'm using DIY co2 right now(planning on switching to pressurized if I can find a good deal).
 
I do have a mist that comes into the tank. I personally really like the mist. I don't think it really causes any clarity issues. There are two reason's i like it.

1. I know my co2 is entering my tank
2. This is a very effective way to add co2 and i can increase and decrease my rate far more than with an external reactor which has a set rate on how much co2 can enter.


The 2nd inline diffuser that you listed has an air stone to break up the bubbles which then mixes with the water and goes into the tank. by breaking up the bubbles makes it easier for the co2 to mix with the water because the smaller the bubbles the higher the surface area.

the atomizer has a air stone in the middle that chops up the bubbles even more which allows even more effective mixing.

my vote is for the second one. I have heard great reviews from similar diffusers. The problem with the first one is that if you try to crank your co2 up too much it'll fill faster with air than water and you won't get that good of mixing.

another options is

these are great I have one and love it.

Love the idea of this one. Have never seen it before. The one i use takes up tons of space a requires a powerhead. Think I should order one and give it a try. Pretty good idea
