We are happy to announce our new addition, the Nano by Cal Aqua Labs.
Up to now, current CO2 checkers on the market look unsuitably large when placed in small aquariums. With dimensions of approximately 3 cm x 3 cm (not including stub), it is perfect for nano aquariums such as the ADA Mini M or Mini S. Supplied with one suction up and 15 ml of ready-to-use indicator solution (4dKh). Available soon at our retailers.
