コロンボ フローラ ニトロテスト 窒素

The two included test tubes and the visual instruction card make the whole process foolproof, even for a beginner like me. After a few drops, the color change was easy to match, and I could finally adjust my plant fertilizer with confidence.

The drip method reads clearly even in low light, and the color chart is dead simple to match against my planted tank’s readings. Took me under five minutes to test all three tubes, and the included accessories meant no extra fiddling.

I was worried about getting accurate nitrate readings for my planted tank, but the adapted measuring range works perfectly for balancing fertilizers. The included test tubes and visualised instructions made my first test hassle-free.
