I would like to purchase a CO2 system and wonder if anyone has any
experience with the Delta Dupla
system?  The only brands that I can locate are Dupla, Aqualine Buschke and
Ceomat (which I don't care for).   I would like something that can be
expanded with a pH controller.  Also, how well does a timer work with a
european system?   Thanks for any information you can give.
