The purpose of this post isn't to debate the +/- of the various brands of liquid test kits available. As many of you long-time reefers know, that's already been done here at Reef Central. I'd like to get your feedback on the dry test strips vs. the liquid test kits.

When I test my NO2 & NO3 using the liquid kits the results are zero. When I use my dry test strips the NO2 shows zero but the NO3 shows a range of 20 or greater.

I've used diff brands of the liquid kits (Aquarium pharmaceutical, Tropical Marine and Salifert) and none indicate a reading anywhere near the equivlent indicated by the dry strips.

What's up with that?

Thanks in advance.
