I've just got Dupla reactor 400. It is a co2 reactor.
I've tried the DYI gravel based reactor, but this dupla thing works like a
dream!
There is a plastic cascade that water falls through and dissolves co2 so
efficiently!
And it looks very cool too.
Had to pay a small fortune for it though.

Hi Chuck!
Actually I think your site is the one I got the plans from...
So more flow is the solution?

Thanks!

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

Sounds the same as my reactor, so I'd bet that low water flow is the
problem.
