Has anyone used the CO2 Pro System (http://www.drsfostersmith.com/Product/Prod_Display.cfm?pcatid=15526&N=2004+113779)?
I was considering puchasing this item, due to price, but was wondering how long will a paintball canister last in a 75gallon aquarium? Does anyone know if you can purchase just the paintball regulator instead of the whole kit? Anyother tips on ways to get "cheap" CO2 would also be apreciated.
BTW, is it true that you need to use silicone tubing instead of the typical vinyl or acrylic tubing with CO2 systems?
