diy co2 not working!

ok so I did everything like I was supposed to. I have a two liter bottle, co2 proof tubing, check valve, bubble counter, and last of all a nano glass diffuser on amazon by aquaticmagic and I just hooked everything up all the way to the bubble counter to see if it was bubbling and it was going at 2 bps. so I then hooked up the diffuser for the first time and let it sit for about 1.5 hours to let the reactor overcome the pressure, so I look at it and there is nothing, no bubbles in bubble counter so I disconnect the diffuser and it squirted yeast and water and sugar in my face (didn't make me happy). does anybody know what is going on? anybody use the diffuser on diy? and my mix is 2 cups sugar 3/4 tsp. and a pinch of baking soda. what is going on?

Yeast can go bad and will not work. What kind of yeast are you using? I would try a different yeast or buy some fresh ones.

no it is working because it bubbles 2-3 bps in the bc when the diffuser is not connected.

Oh. My bad. Maybe just not enough pressure some kinds of diffusers do not work with DIY co2.

If I'm correct, the diffuser isn't needed because its only for pressurized-CO2. I asked advice from a local fish store employee (knows his stuff) and he gave me advice that "the best way to diffuse DIY-CO2 is with a powerhead". Just my $0.02

Definitely the best way to diffuse DIY CO2 is through a power head or the impeller of your filter. The pressure buildup caused by ceramic diffusers is often a problem.

I tried the same thing and those nano bubble diffusers didn't work with my DIY setup. I used to use one that's like a long tube that the bubbles slowly go back and forth up. I forget the name. It works just fine with DIY, and is probably cheaper than a powerhead.

I always diffused DIY CO2 through a powerhead, it works great, just make sure the powerhead intake doesn't get clogged with snails >.>

When I can no more stir my soul to move, and life is but the ashes of a fire
When I can but remember that my heart once used to live and love, long and aspire
Oh, be thou then the first, the one thou art, be thou the calling, before all answering love
And in me wake hope, fear, boundless desire.

Agreed. Remove the diffuser and run the co2 line into the intake of your filter (canister, hang on the back, sponge type - doesnt matter). The media in the filter and the chopping action of the pump impeller will dissolve enough of the co2 for you to see results.

Let us know how the plants are doing.

if you look on the bright side (bcs I did the same thing), you are one step closer to buying a pressurized CO2 system in the near future. This hobby is ADDICTING but I have to add, very relaxing.

I use that diffuser on two DIY CO2 systems and have had no problems. It helps sometimes to squeeze the bottle after some pressure has built up to get the first bubbles through.

If you look at the first photo in this thread https://www.plantedtank.net/forums/ta...-new-pics.html you can see bubbles pouring out of that same diffuser. You can also see my CO2 bottle in the background.

I use a nano diffuser on my DIY co2. I does take it longer to build up pressure. another thing you can try is let it build up pressure with the diffuser out of water, when you hear a hiss place it in tank. My had problems with the pressure from the diffuser and the pressure of the water. Start it dry..worked for me.

I as well use only nano diffusers on all me bottles with nary an issue.

However, what I have found is that it generates a lot of pressure that it makes the setup more prone to having a leak. I wound up using silicone around the tubes on both the top and bottom parts of the lid. Works like a charm.

I also find that Ocean Spray bottles work far better than the 2L bottles. You get a better seal on the cap.

I was going to just let it overcome the pressure of the water that was coming up the diffuser but I am worried the bottle will explode from to much pressure and it is right next to my bed so I am trying to avoid that.
