RE: CO2




I know of several aquarists that use the "CARBO PLUS" and it works very well
for moderately soft water (Fredrik L - you can check swedish prices on
akvarielagret). The drawback is that the carbon sandwhiches are pretty
expensive. For a 60 gal they need to be replaced roughly every 3 months and
they run at about twice the price of a pound of CO2...

The advantages are the ease of use - it is very easy to control the amount
of CO2 injected and it can be controlled with a regular timer to shut of CO2
injection at night. 

Personally I leave CO2 injection on at night - I have a pretty good deal on
refills and it costs me no more than 300 sek (~$30) per year.
