You can stop the reverse siphon by investing in a $2 check valve (sold at
most LFS) Tetratech makes a nice one that has worked for me for a while now.

It started pretty quick. This morning I'm getting 23 bubbles a minute. Is
that too much?
The problem is that when I turn my aquaclear filter down in the morning
when
I feed, it stops bubbling and water siphons back into the hose a few
inches,
then it has to clear it out again.

Hey guys, I just started my CO2 2L bottle tonight about 3 hours ago.
When
usually can I expect some bubble action? I have noticed that the water
is
slowly being pushed out of the hose...I guess this is a good sign. But
it's
hard to be patient. I might stay up all night trying to watch for that
first
bubble...or should I? Does it sometimes takes a few days? Do you usually
see
some froth or anything in the bottle when the reaction starts to occur?
Am
I
asking too many questions??

Thanx alot!

Dave.
