NC02 Test 15ml

Description:

Liquid refill solution for glass CO indicators, designed to accurately assess CO concentration in aquariums. Simply add 15 drops of the liquid to the glass indicator to monitor CO levels through clear colour changes: blue indicates too little CO, green shows the optimal level of 30 mg/L (ppm), and yellow signals excessive CO concentration. For best accuracy and performance, use with the Aqua Nova CO glass indicator.
