Hand Crafted
Each piece is unique. Superior quality.
Crystal Clear
Elegant and cleaner lines.
Visual Clarity
The nano co2 drop checker makes your aquarium look less cluttered. It's a huge upgrade in terms of aesthetics.
Thickened Glass - Durability & Strength
- Using only the highest quality, laboratory-grade, borosilicate glass for maximum strength, durability.
Widened Channel Diameter
The channel diameter is nearly twice that of similar products on the market.
- It greatly facilitates the addition of the detection liquid.
- It facilitates the diffusion of carbon dioxide gas and shortens the reaction time of the indicator solution.
CO2 Indicator Solution Included - No mixing nor preparation required
- It consists of a pre-made 4dKH solution containing the appropriate amount of indicator. Easy to use, no mixing required. Simply open cap and fill CO2 checker.
- The solution comes in a 15ml (0.5 fl oz) dropper bottle for ease of use. The solution will last 6 months if changed on a monthly basis.
Package includes
- Nano Drop Checker X1
- CO2 Indicator Solution X1
- Suction Cups X2
- Pipette X1 (for ease of filling drop checker with indicator fluid)
EXCESSIVE CO2
If the solution in the drop checker changes to yellow, then the CO2 level in the aquarium is too high.
OPTIMAL CO2
If the indicator solution is green in color, then appropriate levels of carbon dioxide exist in the aquarium, and no action is required.
INSUFFICIENT CO2
If the solution in the drop checker changes to blue, then the CO2 level in the aquarium is too low.

I bought this after I started using CO2 injection in my planted aquarium. I would say it is an absolute necessity if you're using CO2 injection. It is super easy to use and I would definitely recommend it to anybody.

Very easy to use product. If it’s green you are a GO! Don’t put this product in the shade, it’ll be harder to read.

My CO2 canister was out of gas for over a week, but the color of the drop checker didn’t change at all. With all the plants in my tank, I’m sure they were starving for carbon dioxide.

Excelente producto y de muy buena calidad, en cuestión de unas horas el color cambia dependiendo del co2 inyectado este producto es de gran ayuda para medición de los niveles y asà no matar a tus peces por niveles de co2 muy altos, la verdad que me impresiono mucho su calidad ya que es de cristal muy duradero y limpio 100% recomiendo. Si funciona lo mejor de todo es que ya incluye su kit completo.
