Description

AF Nitrate TestPro is designed for quick measurement of nitrate ions in marine aquariums.

Nitrate in water is the end result of biological filtration. High concentrations of nitrate cause the growth of undesirable algae. Nitrate levels in reef aquariums should be 2-5 mg/l (ppm). This test kit contains sufficient reagents to perform 40 tests of nitrate concentration.

Tracking reef nitrate with the AF NO3 Test Pro

Nitrate is the end-product of biological filtration, and on a reef it sits in a narrow sweet spot, around 2-5 ppm, where there is just enough nutrient to feed corals without fuelling nuisance algae. The AF NO3 Test Pro is the kit we recommend to local reefers who want a quick, repeatable read on that figure, with reagents enough for roughly 40 tests plus the syringes and vial you need to measure consistently. It is precise enough to guide dosing decisions rather than just flagging a vague high or low.

In Singapore’s warm tanks biological processes run briskly, so nitrate can climb faster than expected after feeding or a missed water change. We suggest testing on a fixed schedule and logging the result, so you spot a trend before algae takes hold rather than reacting once the glass has gone green. Pair the reading with your phosphate result, since the two together tell the real nutrient story.

Find it within our water testing and care range, and to act on the numbers read our nitrate and phosphate balance for SPS colour guide and our nitrate test kit picks.
