Red Sea CO2 Indicator Information



When carbon dioxide (CO2) levels are too low in an aquarium, plants inside it will be greatly affected. Once the plants are affected, it will not be long before fish and corals that are also inside the tank get affected, too. Remember, plants give off oxygen which fish and corals need to live, but plants can only give off oxygen if they have CO2 to use up to begin with.

The first step in making sure that your aquarium has ample CO2 supply is being able to know its CO2 levels whenever you want to. This is where indicators come in. Indicators can tell the you the CO2 levels of your tank, and from there, you can do the necessary next steps.

An example of an indicator is the Red Sea CO2 Indicator from Pet Store. This device can monitor freshwater tanks and give off results in real time, so you'll only get the latest readings no matter when you take them. It also displays the readings in an easy-to-understand visual that has a corresponding qualitative interpretation. With just one glance, you'll be able to tell right away what the CO2 levels are in your aquarium. You will never have to deal with hard-to-read results that could lead to inaccurate readings.

The Red Sea CO2 indicator will turn blue if there's a lack of CO2 in the water. It will gradually turn to green as the amount of CO2 increases.

Real time CO2 monitor for freshwater aquariums

The Red Sea CO2 indicator gives an easy to read, continuous, qualitative visual indication of the current CO2 level in a freshwater aquarium.

Better than the Azoo Product Review by Andrew (Posted on 2/26/14)
Rating
Excellent!

Comments: I got this one after I had issues with the Azoo CO2 indicator. I had lots of problems with the Azoo especially with it leaking and having trouble with the provided suction cup staying attached to the glass. The Red Sea is much easier to use. It also requires less indicator drops per application than the Azoo. So far there have been no leaking or any other problems with it. Thank you guys for the great service.

Does a good job, but... Product Review by SHAHRIAR FARKHAN (Posted on 2/6/11)

Great!

Comments: It works, and does a good job, the advantage of the bright white plastic is it's visible (from across the room, LOL) and easy to read.The disadvantage is the bright white plastic is gaudy and in a green lush aquarium, looks out of place - I was originally looking for a glass indicator because they look a lot better in a planted tank but no luck. The only caveat is the instructions, they require you to use aquarium water and I've been told by almost every planted tank expert that you need to use 4dKh standardized water because aquarium water may have buffers and may not be 4dKh as necessary to make the indicator accurate. You can do an online search for 4dKh and you'll see a number of posts in online forums.

Great!

Comments: Works well for quick Co2 checks. It can be a bit of a hassle to get it put back together but this insures that it does not fall apart while in your aquarium. I think that this is a must for someone who does not have the time for constant Co2 checks or the money for a monitor/controller.
