When you use a diffuser do you place at the bottom of the tank so the plants aquire the co2? or does it mix in the water? Does the same apply to an aistone? can someone explain this to me please because im confused. Thanks -AF
 
A diffuser just makes the CO2 bubbles smaller (the smaller the better). The lower the diffuser the longer the bubbles take to get to the top (longer contact with water, better mix in water). Most airstones have pores that are too big for CO2 use, but can be used---it would just waste a little more CO2.
 
Hi. I have a Hagen Plant Grow Natural System on my 15 gallon planted tank, and I think it works really well. I have the diffuser about mid-way down the back wall of the tank, and that seems to work just fine. By the time the bubbles make it all the way through the diffuser "maze", they are really tiny. All my plants are growing well, so I could say I would recommend this brand. I got this system-it is very inexpensive, at Petsmart. You'll just have to change the stuff in the fermentation chamber once a month, but that's no big deal. For a larger tank, a more high tech system may work better though.
 
well Ill look into getting one of those Hagen C02 Systems because if your plants are doing well and you have the same size tank as me might as well get one... do you think it could work on a diy method recipe? (PiscesPrincess)

I am also researching Co2 ... purchased a ready to go regulator and will be looking to pick up a few more items.

If you wanted I think you might be able to use a reactor instead of a diffuser to get the Co2 into the water. I also keep reading that a double membrane diffuser is very efficient - claims to diffuse 100% of the Co2 and it would be less sightly than a reactor. Still havent made my mind up as to what I am going to go with.
