Regulators and solenoids are essential pieces of equipment for the control of CO2 in the planted aquarium. Solenoids are particularly useful as they cut off the CO2 supply to your aquarium when they lights are off, therefore saving you money and making the aquarium environment safer at night for your fish, when plants expire CO2. If you don't use a Solenoid you run the risk of causing oxygen starvation of your fish and big pH fluctuations.

Plants only absorb CO2 when your lights are on, so there is no point in adding gas at night time. Not only is it wasteful, but carbon dioxide binds to oxygen and you can cause major distress or death in your livestock.
The Colombo CO2 Solenoid should be used with a domestic timer (just like your lights timer) and automates when your CO2 comes on and off. I recommend it comes on 1 hour before your lights come on and turn off 1 hour before they go off (this is optimal). By using this solenoid you will not only save a lot of gas, reduce any risk to your fish/shrimp and save you plenty of money (as you won't need to purchase CO2 bottles as often!).

If you never test, how do you know? Making sure you have good CO2 levels is so important in a planted aquarium, it cannot be stressed more. Quite often hobbyists guess or
assume it's OK when the realisty is that it rarely is. This drop checkers lets you know what your CO2 levels are all of the time giving you peace of mind.
Benefits:
Easy to read
Stylish design
Contains enough indicator for 2 years
Contains free clear suction cup
Very simple set up (takes seconds)
The drop checker is a relatively new invention and previously test kits were used. However, they only measured the levels at the time of the test whereas the drop checkers measure it 24/7.
