VIV's hand-blown Glasswares are the most favored in the aquatic world offering an outstanding elegance to any aquarium. Designed with an emphasis on functional beauty, each VIV glass piece is handmade in China by skilled glass workers. The pieces are formed from crystal clear borosilicate glass, the same material used to make high end lab equipment. Japanese glass craftsmen carefully hand finish each VIV part to the highest standards with smooth edges and attention to the smallest details.

VIV's CO2 glass drop checker allows you to monitor the CO2 level inside your aquarium. It is designed to hang on the glass and is easy to use.

Use with Up Aqua or AZOO CO2 indicator solution.

Directions: Fill bubble 2/3 full with CO2 solution, then hang on the aquarium with the round area with solution outside of the tank. When you turn the drop checker upside down it should not spill the solution out or you filled it too full. Checker will not read accurately for 6 hours. If the solution turns yellow, reduce CO2. Blue is the start color which indicates when the CO2 is too low. Green is good and what you want to see.
