## Description

Measure the nitric acid concentration (NO3) in the aquarium (freshwater and saltwater). Nitrates are produced next to nitrites in the decomposition of organic substances. In addition to disassembling nitrogen containing substances, it may also enter aquariums or garden ponds through tap water. Over 50 mg/L will weaken fish and aquatic grass and moss. Do not exceed 20mg/L.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 検査の時間が早く済む
*by ら***ら on August 16, 2024*

他社試薬も使っていますが、セラは時間短縮で結果が出ます。3本中の1本、試薬1滴目が傾けている時に急に出て焦りました。自分の混ぜ方が下手なのかもしれませんが※粉が溶けにくく時間が掛かる。 振りまくると蓋の隙間からやや漏れる。※の部分は他社製品と同様です。けれど、海水水槽に試薬は必須。試験紙はアバウトと感じるので手放せないです。

### ⭐⭐⭐⭐⭐ 精度良し
*by E***G on April 6, 2023*

20ppm未満の濃度を測りたかったのですが、試験紙やph試薬だと精度に限界があり厳しいので、高かったけどこちらを購入。約3ppmごとに色が変わってくれる実感があって大助かりです。

### ⭐⭐⭐⭐ キャップ開けづらい
*by あ***さ on April 5, 2020*

硝酸塩の管理がシビアな海水水槽用に購入。蓋を開けられずに苦労しました。説明書どおり下に押し下げ反時計回りなのですが、一部のキャップは空転して最初、固定部分と分離できず開けられなかったです。 諦めてカッターナイフで固定部分と分離させました。
