PRO NO3 Test

This JBL kit measures nitrate (NO3) concentration in aquarium water. It suits keepers who dose fertilizers into their tanks and need to know how much nitrate is actually present before adjusting doses. Without a reading, fertilization is guesswork, and excess or deficient nitrate can harm both fish and plants.

Why it matters

• High nitrate concentrations can be dangerous for fish, so the kit allows the level to be checked before it reaches a harmful range.
• Both a deficiency and an excess of nitrate are unfavourable for plants, so the test shows whether the plants are receiving the right amount.
• The results are used to select appropriate fertilizer doses, which makes dosing a measured decision rather than an estimate.
• The set includes a separator, a measuring scoop and a syringe, which are needed to prepare each sample in a consistent way.

What it works with

The kit is designed for aquariums in the aquatic exotics category, specifically for tanks that are fertilized with various types of fertilizer. Because the test result drives the dosing decision, it is most useful alongside the fertilizers the keeper already uses in the tank.
