diy c02 diffuser

I thought this diffuser was a pretty smart idea i tried it and it worked but mine is suction cupped
He says in the description that he plugged the end of his airline with a shortened syringe cap then used the syringe to jab about 20 holes into it luckily i had a syringe at my house and worked great seems the smaller the needle the better

Looks like most of the gas is reaching the surface and is being lost, very inefficient. Possibly putting it right under a filter intake, so it all gets sucked up and mixed by the impeller, will help.

If you want cheap and effective, and you have a canister filter, then just DIY a PVC inline reactor.

yeah mines under my filter intake and mine seems to do a little better than his but still good idea if someone (like me ) is waiting for my diffuser to come in lol
