>>David S. Brown said his new CO2 ceramic diffuser started bubbling slowly
them let his CO2 tank dump.<<

I may be mistaken Scott, but I don't believe he said he had a tank dump, he
said he turned the co2 up too high because initialy nothing was coming out,
and he left it at that level before going to bed. There does seem to be a
delay turning on the CO2, its an easy mistake to make.

After messing around with the Ehiem diffusor and Daves system for a year and
a half, (before he added a needle valve) I had simular probelms, and found
it very difficult to get an even and steady amount of CO2 coming out of the
diffusor. It was extremely irregular, the disk needed constant cleaning to
prevent large bubbles from forming instead of the fine mist, and streams of
bubbles were always coming out from the edges of the disk, and other places.
It was extremely hard to regulate a bubble count... turn the CO2 up a notch
and I would get niagra falls coming out of the diffusor, turn it down a
notch and I would barely get anything. Perhaps the addition of a needle
valve has improved it somewhat, but I will NEVER again use any sort of
diffusor as opposed to a reactor which mixes the CO2 with water. To me its a
no brainer. Reactors, (which are clearly defined) are far far far more
efficient and more stable.

I also do not see how that tiny little device attached to the Ehrim diffusor
can be considered a true and accurate bubblecounter. I challenge anyone who
has one to count the number of bubbles...and then hook up a real inline
bubble counter at the same pressure and see if these two so called
bubblecounters match up.I could be wrong...but thats my opinion.
