Description

CO₂ indicator which measures CO₂ levels in your planted aquarium.

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 where as the drop checkers measure it 24/7.

It's amazing the difference the way your plant will respond when you have the correct CO₂ levels and this Colombo CO₂ Drop Checker will be one of those tools that you won't believe you lived without for your tank. An absolute must for any planted aquarium tank.

Easy to set up and put in the tank, read instructions then two minutes set up in the tank. The Columbo Co2 indicator does what it says on the box, well worth it.

Easy to install and gives clear indication of CO2 levels. Really glad I bought this as I am a CO2 novice, and I was worried that I was going to upset my fish. It has reassured me that the right amount of CO2 is getting into the water to keep both plants and fish happy.
