Are you using a canister filter? If so head on over to
www.aquabotanic.com and look at their DIY forum. There are some great
DIY reactor ideas over there using PVC pipe. I have built three of
them and they work great.

Hi THere,

I've followed the basic idea -
Flow input to a vaccum from a gravel cleaner -
bio balls
sponge at the bottom.
1 bubble per second

Problem is the canister fills with co2 - like an air pocket of Co2 -

Is this because there is not enough water flow or ?

Thanks!
