Okay I'll have to take you up on your offer because last night my martini read 0 on the display I must have done something wrong because it was 0.02 earlier in the day...
My denitrifier does do a 17 gallon water change every 4 hours that drops trates and phates to 0... But I can't believe 0 I'm hoping this thing works...LMK a good time to stop by..
Wow just tested again and it's 0.04 I believe this reading.. I dosed nitrates into my tank for a whole month... last month so it should take about 1 more week bef=ore it's back down as low as it can go... I'll be around you around 1:30 today I'll call you first..
