Nitrate levels and reactors

[Bryan]

Ditto for me, almost undetectable Nitrates using a Lamotte test kit, and all I have is a skimmer , liverock and barebottom tank. I actually add some Potassium Nitrate weekly to bring up the nitrates so my macroalgae has a chance to grow.

I have never had high nitrate levels, not sure why, I've done nothing special to control them. Typically, I have less than 2-3 ppm, testing done with a Salfert kit, I can just barely distinguish a slight tint of colour in the solution when viewed through the side of the vial. Looking from the top down, I can't even tell its changed colour at all.

Am I just lucky or is this not unusual?
