I have 3 mixed reef tanks with fish. 2 75 gallon and a 120 gallon. Tanks have been up and running between 1 and 3 years. The standard readings on my Apex Trident are all within range--Alk 9.52, Ca 514, Mg 1335, ORP 422, pH 8.02, Salt 35.8 and temp at 78. I ordered the Hannah Checker Nitrite ULR and tested for the first time today. The readings are 32, 44, and 71. First, do I need to multiply those numbers by 3.29 or not. Secondly are these numbers I need to worry about?
