Many planted tank hobbyists, especially those in Australia, avoid using CO2 because they believe that it is too expensive. For those living in Australia, I would tend to agree. CO2 canisters can be very expensive depending on where you purchase them from. In all honesty, this is the reason why I have spent the majority of my time in the hobby dabbling in various ‘low-tech methods’ of maintaining a planted tank. Besides, who doesn’t love saving money?
However, after many years and much research I made the switch to pressurized CO2. I should add that this decision was largely influenced by the affordable price at which Keg King was offering their CO2 systems. Keg King provided the CO2 canister, as well as, a regulator with a magnetic solenoid valve and a built in bubble counter. This cost me just over $150 dollars. Considering that the average hobbyist can easily spend this much money on a single visit to the local fish store, I didn’t consider this a significant outlay. I expect that the CO2 canister will last at least a year, so the investment was a long term one.
The CO2 Canister
The CO2 canister is a 2.6kg canister which stands 47cm high and has a diameter of 14cm. This will fit comfortably under many aquarium stands and is small enough to be unobtrusive when place next to the aquarium. The canister has a carry handle which allows for easy transport. This will be helpful when I have to refill the canister.

The Regulator with Magnetic Solenoid Valve
The regulator allows you to connect the CO2 system to a timer so that the CO2 will switch on and off at the same time as your lights. This prevents you from having to manually switch the CO2 on and off every day and ensures that you do not accidently asphyxiate the fish during the night, when CO2 levels rise due to plant respiration.
The regulator also comes with a built in bubble counter. The built in bubble counter is favourable, as it means that you do not have to suction cup a standalone bubble counter to the side of your aquarium which can be unsightly.

Thus far, I am very pleased with the way that both pieces of equipment have operated and I have had no issues. Keg King is arguably the cheapest supplier of CO2 equipment in Melbourne, so if you live in Melbourne and would like to setup a high tech planted tank, I would highly recommend purchasing your CO2 equipment from them.
