Mighty Mini C02 diffusor?

I'm considering adding a DIY CO2 setup to my newly planted nano.

http://www.aquabotanic.com/abstore/index.html
C02 Systems and equipment
towards the bottom you'll see Mighty Mini C02 diffusor

#1 Anyone had experience using this diffuser?

#2 Does anyone know of an alternate source for this product? I'm interested in something very small for my 2.5g, and this caught my eye. The only problem is it is currently out of stock.

#3 are there alternate products that I'm overlooking for C02 diffusion via a small DIY setup?

Thanks in advance for your help!

Thanks for the info.
After reading those posts I guess I will wait until aquabotanic has them back in stock before ordering. I'd rather wait and have one that is verified to work w/DIY CO2.
I will make due with a limewood airstone for the time being.

Does anyone here have experience using one of the above diffusers with a smaller sized CO2 generator....say a 20oz bottle? Any ideas if that will create enough pressure?

Any DIY CO2 bottle is capable of generating enough pressure. The problem is that the bottle isn't strong enough to withstand the pressure. If you can use a strong juice bottle, with a good cap, with the outlet tubing well secured you should be able to hold the 2 to 5 psi needed. But, a failure will blast yeast and water all over the place, and possibly let the tank water siphon out. So, if you enjoy taking risks, enjoy!!

Good point Hoppy. I'll probably be using a single serving apple juice bottle not a 20oz soda bottle. That should be strong enough to withstand the pressure. Just in case I'll have a check valve installed and I plan to keep the bottle contained inside a small bucket. The last thing I want is a huge yeast mess all over my desk at work.

I think the weakest point of this setup would be the tubing connection to the bottle. I think I can solve that by using brass barb and drilling the cap to ensure a secure fit.

I skipped the DIY CO2 stage on my home tank and went right to pressurized, so this will be my foray into DIY.

What I'd really like to find is a reasonably priced mini pressurized setup, but it doesn't appear that one is available commercially. If I could figure out a way to retro fit a regulator on a ~90 gram paintball CO2 tank I could avoid the pain and variability of DIY CO2.

Maybe not the most cost effective way to run pressurized but they do have a regulator for some paintball systems - $80+

Hope that helps!

Total mini CO2 package setup!!!

Thanks for linking that post Krazy...I'd never seen that thread before

Looks like I could get a complete CO2 mini setup using this regulator
http://www.octopustap.com/cart/produ...products_id=49

I can get a 9oz paintball tank locally.


Rough costs
Regulator $105
Shipping $10
9oz paintball tank full $25
needle valve $15
Limewood airstone $5 (until the diffusers are back in stock)
Total cost ~$160

At some point I'd probably want to add a bubble counter /solenoid, but that could wait.

I'll have to think about this option. It's not cheap but convenience is generally worth it in the long run and given the location of this tank on my desk at work it's probably the best overall solution.

If I do decide to purchase I'll post some pics when I get it all setup.

too late with my suggestion but the info is here for all to reference

i setup my 20 oz co2 tank for my 10 gallon here is what i used and cheaply

i went to lowes and bought a Watts model A-41 needle valve = 6
i also bought thread tape in the same aisle = 1
aswell as co2 tubing "0.170" a roll of like 30 ft = 2.50
then the co2 tank at walmart = 24
then to the local paintball shop for a drop forward valve = 16
co2 fill up since the new tank came empty = 3.50
for a grand total of around 55 dollars

well if you already have a tank then it should come out to around 30 dollars or less considering the price for your local co2 fill up
