CO₂ Counter was developed to measure the safe amount of CO₂ to be added to an aquarium tank, and a timer was developed to automate the daily addition of CO₂. Let us introduce the evolution of the CO₂ counter and timer.

Establishment of an index for the CO2 amount added

The amount of CO₂ added was measured to ensure that photosynthesis of aquatic plants would be active and that the amount of CO₂ added would not be excessive for shrimp and other sensitive organisms. CO₂ Bubble Counter is made of glass to be installed as an aquarium peripheral device, and the current shape was adopted so that the size of bubbles can be easily counted. CO₂ Beetle Counter was developed to measure bubbles in larger size for large aquarium tanks that require much more CO₂. The internal glass plate rolls are handcrafted by craftsmen and designed with a beautiful and unique spiral structure. Similarly, the CO₂ Twist Counter, which facilitates addition measurement, can practically count the amount of  CO₂ by incorporating a special spiral glass piece.

Automated photosynthesis promotion system

The NA Control Timer is not a simple timer that turns the power on and off. The NA Control Timer II has a redesigned aluminum body and improved operability with a dial-type setter. Power Cord S-70 is a product developed in line with the improved IoT technology, which enables smart and ideal operation. The Power Cord S-70 is also designed for precise maintenance of DOOA system aquariums, with ADA’s unique setting having 70 routines programmable. The use of a special metal cover prevents water damage to the power supply unit.
