Hello, Have just started new planted tank, Aquatic soil and Co2 with a large jbl .? Plastic spiral diffuser. The Co 2 drop checker is not changing colour at all, just stays blue. Co2 cylinder is new with approx one bubble per second Into the spiral. Could the Bromo blue be faulty, its 4 or 5 years old, any help appreciated. Cheers
