Yes it works just fine since the tester takes a baseline reading. I checked it several times by testing before first dose of furan 2 and then after. Test was always within the .05ppm variance of the tester.when using copper power and kannaplex +furan 2. Since Furan 2 will change the tank water to yellow Tint. Will you still get an accurate reading on the Hanna checker?
thanks
