Customer Review

For 3 weeks the water with these strips measured. Has always displayed top values. During this period, 50 shrimps died.
Yesterday went to Fressnapp and there made free trial. It has now shown that NO2 is in the worst area. Under no circumstances rely on these test !!!!!!!!!!!!!!!!!!!!!!!!!!
