CO2 tank for 5ft planted tank.

[tetra]

Hi,
May I know what size of C02 tank is good for 5x2x2 planted tank?
What size should I get at least will last me 6 months and above for 3 bubbles per second?

Also, the most important thing - the solenoid, which one should I get, I mean reliable. Pls dont suggest Dennerle, anybrand equivalent?
Appreciate your help!

i think a 5l tank should be sufficient.
you can check with chan at nature aquarium. he would be able to advice you on co2 tank size as well as the solenoid.
