Salifert Nitrate Test Kit


Item #: SF1129

In Stock

Nitrate Profi-Test
  • When there are insufficient areas of a tank which are deprived of oxygen (anaerobic zones) or denitrification is not taking place properly, nitrate will build up. This can also happen in an aquarium where the biological loading on the system is causing an imbalance e.g. if there is excessive livestock for the aquarium volume or over feeding is occurring.
  • The build up of nitrate can result in unwanted algae growth and the slowing down of coral growth.
  • The nitrate concentration in a reef aquarium should be lower than 1 mg/L, although fish only aquariums would usually have a higher concentration.
  • Just as with nitrite, many nitrate test kits are prone to amine interference which can make the levels of nitrate appear much lower than they actually are.
  • The Salifert test kit does not suffer from such interference and gives accurate and quick results with a total testing time of less than 3 minutes.
  • The test kit’s range goes from a very low to a very high nitrate concentration (approx. 0.2 - 100 mg/L as total nitrate).
  • Sufficient for 50 tests.
This test offers two ranges:
Low range: 0.2 - 10 mg/L (ppm) as nitrate.
Medium range: 2 - 100 mg/L (ppm) as nitrate.

Clean test vial and scoop after use. Store this kit in a dry place.

Best test kit in the market for nitrate

Pros: Very easy process.

Cons: Each person has different observation capability. That means results may very person to person.

I seen other test kits reviews before making the final decision. I find that this test kit is recommended by the most people.

Best NO3 kit

The top down view is unreadable. I always use the high resolution from the side. Works fantastic!

Good test kit for nitrates

Pros: Easy to use, Inexpensive

I find this to be an easy to use test kit for keeping an eye on your nitrate levels. It takes about 5 minutes and you are done. Simple to use and worth the price. Its about $10 cheaper here on the MD versus my LFS. Definitely recommend.

Easy, Accurate

This is the second time I have bought this kit. It is the only Nitrate test kit I have found that is not over complicated and it seems fairly accurate. If you have high Nitrates the colors differences are fairly easy to make out and if you are measuring low Nitrates (mine usually run in the 0.2 range)there is an easy conversion scale for that. The price is reasonable. The kit advertized 50 tests and my last one lasted a year doing once a week tests so it was pretty close to 50.

Hard to Read

I like that that test instructions were clear and easy to do, but the color never matches the colors on the card. It's hard to for me to guess which one it's closest to.

Money well spent. This doesn't cost much, is accurate and is vital if you have a reef tank. I find this Salifert test kit to be one of the best at accuracy. It's simple to use and you know your nitrate levels within 5 minutes. Definitely a good test kit to pick up.
