Colombo CO₂ Indicator

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.

thank you very much. very fast delivery and works well. Tom.

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.
