Pressurized CO2 Tank Sizes

[bcarl_10gal]

I have been doing research on different types of pressurized CO2 setups and wanted some opinions. I want to go with the Aquatek regulators but I am still debating on what size tank to get. I am debating between a 5# and the paintball setup. It is a 10gal right now but I will be upgrading to a 26gal in the future. The tank is heavily planted. If I went with the paintball setup how long would it last on the 10 and the 26? How long would the 5# last on both? Also is it worth the extra money to get the 5# tank? (I have places to get both filled)

If you have the room I'd definitely get the 5#. With the solenoid on a timer, it will probably last 6+ months. I have the Aquatek paintball regulator and a 20oz lasts me 2 to 3 months on a timer with about 2bps in my 26g. I went with paintball because of space restraints in my stand. Its not so bad because the local airsoft spot gives 5 free refills if the co2 cylinder is purchased from them.. So at $25 for the co2 tank, and at $5 a refill..i got it for free basically. I bought 2 tanks so i don't have to get refills as often.
