This is everything that you need to start monitoring CO2 levels in your aquarium.
Drop Checker is an original glassware product, designed to indicate the CO2 amount diluted within the aquarium water with color change of the pH reagent inside, in order to understand the proper amount of CO2 supply.
Drop Checker Size:
Very happy well made unobtrusive in the tank and as stated previously the service is excellent
The colour of the fluid is hard to read for me. Reflection??? Background colour (wood in the tank)??? Drop checker itself is made of glass, which I love. Cleaning is easy. Refilling is easy.
Easy set up. Good instructions. Works great.
