Going through the cycle on our new tank. Dosed Mr Tim's One and Only and 2ppm Dr Tim's ammonium chloride day 1. Now on day 3 and the ammonia has read 2ppm every day on the Red Sea kit, but now we've got our Seneye working and it says 0.086ppm (but still reads 2ppm on the Red Sea kit). Which would you believe? Tempted to add another bottle of Dr Tim's and buy another brand of test kit (incase the first of either was a dud)
