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.

Columbo co2 indicator

At present waiting a reply from aqua essentials, as my columbo indicator is leaking fluid into my tank , it is amazing when it is first put in the tank , so easy to see the colour , my old glass one was somewhat difficult to see , with the columbo indicator having a white background it is perfect so easy to see what the colour is , shame by morning all the fluid is gone, completely full with tank water . If it didn’t leak would’ve been five stars , lucky to get two

We're onto it and have contacted Colombo to arrange a replacement

Normally I struggle with the installation of such technology.
However, even I found it simple and it is working perfectly

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.

I'd been merely estimating the CO2 levels in my tank based on the bubbles-per-second going in for months. However, after setting up the Flora-Grow CO2 Indicator (which was extremely simple) I was quite surprised to see that the amount of CO2 actually making it into the water was way too low. I tweaked up my CO2 flow over a few days, and finally got the indicator to go green -- turns out I had to actually double the CO2 rate to accomplish this! And yes, my plants have all responded with gratitude. I never would have risked doing this however without an indicator -- it goes yellow when the levels are too high for the fish. Now that I've used this, I would never inject CO2 without an indicator again. This particular model is a little utilitarian in its design, not ugly by any means but I've seen more artistic models. At the end of the day this does exactly what's required of it and the 2 year supply of indicator solution is a particularly nice bonus.

I was amazed at just how low my CO2 was, if you use or intend to use CO2 it is a must.
