DIY CO2 Diffuser !!
Hi all , I want to make a DIY co2 again, and this time I dont want to use an air stone as diffuser as it often get slimy, and i hate that.
Could anyone share with me, how they did theirs ? I heard some people can use ceramic rings, and other things better than air stone.
I dont want to search thru the net, coz i trust most member here more about their testimonial.
Thanks all ^^

just run the co2 into a powerhead dude. Whether co2 diffusers are better than this im not sure. But a guy with a very successful planted tank uses the powerhead method.

im thinking about stabbing the CO2 air tube directly into the filter outflow.
in theory it makes sense. making the CO2 run through the course of the outflow pipe making it bounce around abit before going into the tank.
though this is still in the conceptual stage. i'll tell you guys how it goes when i try it out.
cheers,
Eric

i tried using powerhead but sometimes the yeast in the bottle get sucked into the water and mess the water up. Also , I cant adjust the amouth of CO2 being released into the water.
I saw people using like a gravel vac , and inside the vac, there were bio balls ???? Anyone use this thing ??

i just built a DIY CO2 reactor with the afforementioned method (syphon with bioballs) etc...
It seems to be working effectively.. i only put it on my main tank today, so i cant report any gains as yet....
Will keep you guys posted (if theres an interest) and can post pics too
Regards
Benny

buy an otto 800lt per hour power head
and a standard gravel vac
the end of the powerhead and the otto fit the same size tube (13mm) you just need a 90degree elbow from your local bunnings ($0.90)
then drill a small hole in the top of the gravel vac, insert your co2 tube there, that will stop yeast backflows
the 800lt otto has the exact power to run the diffsuser properly, you just need to add 4 large bio balls to the gravel vac and glue the last one in
works perfect
any bigger than an 800lt and the piping won't fit
(the only time you may have a probelm is in the start of the co2 cycle when the reactor lets off excess co2, the diffuser won't quite keep up, just turn of the diffsuer for one minuate to let the excess co2 get away)
