## Description

Full description not available

## Features

- Easy To Use: It consists of a pre-made 4dKH solution containing the appropriate amount of indicator. No mixing is required. Just fill the carbon dioxide monitor drop checker 1/2 full of indicator solution and place it in the planted tank with the help of the suction cup.
- Precise Readings: If the indicator solution is green in color, then appropriate levels of carbon dioxide exist in the aquarium, and no action is required. If the solution in the drop checker changes to blue or yellow, then the CO2 levels in the aquarium are too low or too high, respectively.
- Essential Item: You need to be very careful about your plants' health; carbon dioxide is one of their major requirements. This CO2 monitor kit is one of your aquarium kit's most vital items that helps you keep a constant check on CO2 levels in the water.
- Quality Guaranteed: The drop checker is made of the highest quality, laboratory-grade, borosilicate glass ​for maximum strength and durability.
- Complete kit includes: 1x glass drop checker, 1x bottle of pre-mixed indicator solution (15 mL / 0.5 fl oz), 1x pipette
