Ideal Nitrate Levels

[SirMinion]

Hi...does anyone here have trouble reading the nitrate levels with Aquarium Pharmaceuticals color card? To me it seems that after 40, all the orange colors are too close to distinguish? Are there better nitrate test kits? SH

Ha. I'm colour blind as well so those cards are totaly useless to me. It's about time someone developed a test that had a visibility scale rather than a colour scale. Then there'd be no doubt.
