Glass Diffuser

[Dave1]

does anyone have a Glass co2 diffuser? i got one off ebay and i haven't seen any action with it... im not sure whats going on... i had a cheap air diffuser before and i was getting a constant stream of small bubbles, but it changed to large bubbles, so i got the glass diffuser and i dont think its doing anything...

(im doing DIY w/ yeast and sugar in 3 2L bottles... it seems like it was working better with the 3 than with just 1, i got a "recipe" from on here or some other site, but it was being exhausted too quickly so i am using 2 packets in 3 bottles or 66% the amount of yeast. and it was going for a WHILE)

I'm in the same boat as you and just bought a glass diffuser for my DIY setup. Actually I think I got 3 somehow... we'll see how it comes out!

 

[Dave1]

where'd u get urs?

The diffuser is probably the most important item of your equipment. Inexpensive air stones waste precious co2. Bubbles are large and do not maintain contact with the water long enough, and are little use to good oxygenation. Diffusers are made of ceramic with tightly formed pores. The require 25 to 35 lbs of pressure to force the oxygen through ceramic pores, resulting in micro-fine bubbles. The bubbles are so small that they stay suspended in the water and the water absorbs the oxygen. Ceramic diffusers will give many years of service. If the pores clog at the surface due to impurities in the water, a light sanding on the ceramic surface will generally solve the problem.

I dont know how to test if your bottles are creating enough pressure, but i'm guessing that's your problem, or you have a leak somewhere right

i dont have a leak... i squeezed the bottles VERY VERY hard, and they r good, i think im gonna put 150% the yeast in all the bottles instead of 66%... that should work, right?

I got mine on ebay, dont remember the sellers name ATM though

I have a DIY set up using 2 - 2 liter bottles and a glass diffuser and I'm getting good results. I bought a Spio III from E-bay. If you look at different types of diffusers some aren't compatible with DIY set ups, but I'm sure you purchased one that was. For a 2 liter bottle I use 2 cups of sugar and a teaspoon of yeast. I change one bottle every week.

i bought this

 

[nicklfire]

what's the point of the spiral , never could figure it out

 

[Dave1]

count the bubbles maybe?

You gotta soak the ceramic. Make sure its good and wet. Then squeeze the bottle to help the flow get started. Sometimes it just a half day be patient. A watch pot never boils. I had the same problem, and I have the same diffuser. Mine works like a charm.

 

[Dave1]

its been in the tank for 24 hours... and still nothing... wtf?

I had the same problem as you. There needs to be an large pressure build up to get through that cermaic disk and any little leak will result in the diffuser not working because the pressure just gets out.

I have a Rhinox 2000 from Aquatic magic with 2 Nutrafin kits going into it on half the yeast (½teaspoon) and I am getting loads of bubbles from the diffusor and the drop checker is always mid to light green with the 4Kh reference solution and 4 Ph drops, so it must be on the money I guess.

I must add that the Rhinox 2000 is for my size of tank which I checked out before buying. Different diffusors are made for different size tanks because a larger tank will require more Co2 to maintain the same ppm in more water.

So if you bought a diffusor for a larger tank it may not work because you can't build up enough pressure to produce the level of CO2 the diffusor wants which in a way is good or you would get far too much CO2 in your tank.

E-mail the seller and ask what size tanks it is reccomended for.

im geeting a spio 111 diffuser and it says above 20 gallons and mine is 28 so hopefully it will work if not
