Description

- Easier to read:
Other Drop checker kits may be hard to read. This is why we include the optional darkening agent, which you can add to the premixed indicator solution to make reading easier in high light tanks or tanks with dark backgrounds.

- Easier to use:
Comes with pre-mixed indicator solution, pipette, and suction cup. Fill the glass chamber and place in tank. Wait about 30 minutes for the color to fully change.

- Do Not add tank water into the drop checker chamber.

- Pre-Mixed 4.2 dkh solution included, (Green at 30ppm dissolved CO2)
By keeping the drop checker solution near green at all times, aquarists can ensure optimal plant growth while keeping fish and livestock safe.

The kit works by changing color as CO2 levels rise and fall. Too much dissolved CO2 can be harmful for fish and livestock. With this kit aquarists can accurately measure optimal CO2 levels that promote plant growth while helping to keep fish safe.
