The Salifert Oxygen Profit-Test is extremely fast, measuring oxygen levels in just a few minutes and is scaled from 2 - 14 mg/L. Sufficient for 40 tests. Can be used for marine, fresh and garden pond water Warning! Reagent O2-1 is irritating and contains a base. In case of contact with the skin wash with plenty of water. In case of contact with the eyes wash with plenty of water and consult a physician immediately. If swallowed contact a physician immediately. Keep out of reach of children. Not for consumption. Instructions: Add to the test cial 5ml of water. Add 5 drops of O2-1 and swirl gently for 20 seconds. Do not shake since this could change the oxygen content of the water too much. Add 6 drops of O2-2 and swirl gently for 15 seconds. Allow to stand for marine water 5 minutes and other types of water for 1 minute. Add 6 drops of O2-3 and swirl for 20 seconds. Allow 30 seconds for color development. Place the test vial on a white part of the color scheme and compare the colors by looking from above. An immediate color corresponds to an intermediate oxygen content. The values on the color chart are in mg/l (ppm) oxygen. Try to maintain in fresh water (aquarium of garden pond) an oxygen content of 8mg/l or higher. In marine water an oxygen concentration of at least 7mg/l is advisable. Some fish need higher oxygen concentrations. Review: easy to use and has worked every time except the ... - easy to use and has worked every time except the first time I tried to use it, the water stayed clear, so I think I did something wrong. Is giving me pretty consistent readings on 3 different tanks for a week, so I'm happy with this purchase. Even though I thought the price was too high, it's worth it to know, especially since I did end up needing to add more oxygen to one of my tanks. Review: O2 water test kit - Took a few tests to get used to. Shows higher o2 than it should in low o2 water and shows lower o2 levels than it should in higher o2 water. Definitely not accurate but good enough for a baseline guesstimation. I would compare its o2 accuracy to a bit less than litmus strips are for ph. If you want to know exact oxygen levels don’t use this product. Go spend a grand or 2 on a real o2 tester/meter. But if you just want something cheap and not precise and more of a guide in your guess work then I recommend this product. ## Features - Corals and marine fish require very high levels of oxygen concentration because of the low solubility of oxygen in salt water so it is very important to regularly test the level of oxygen present - The Salifert Oxygen Profit-Test is extremely fast, measuring oxygen levels in just a few minutes and is scaled from 2 - 14 mg/L - Sufficient for up 40 tests - Can be used for marine, fresh and garden pond water - Made in Holland ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00NMI6BP0 | | Best Sellers Rank | #132,043 in Pet Supplies ( See Top 100 in Pet Supplies ) #212 in Aquarium Test Kits | | Brand | Salifert | | Brand Name | Salifert | | Customer Reviews | 4.3 out of 5 stars 208 Reviews | | Global Trade Identification Number | 08714079130446 | | Included Components | See Packaging | | Item Type Name | Oxygen (O2) Test Kit | | Item Weight | 0.4 Pounds | | Manufacturer | Royal Aquatic LLC | | Recommended Uses For Product | Aquarium | | UPC | 714079130444 | | Unit Count | 1 Count | ## Product Details - **Brand:** Salifert - **Manufacturer:** Royal Aquatic LLC - **Recommended Uses For Product:** Aquarium - **UPC:** 714079130444 - **Unit Count:** 1 Count ## Images ![Salifert Dissolved Oxygen Test Kit - Image 1](https://m.media-amazon.com/images/I/81+JVnopa4L.jpg) ## Questions & Answers **Q: The "product description" is for Nitrate, the title says O2, which kit is this?** A: The front of my box is the same. My instruction sheet inside says Oxygen Profi Test. The side of the box says there are other tests available, Nitrate is one of them. Mine works fro O2 **Q: does this kit work for freshwater?** A: I use it in my small pond. My pond is filled with tap water- so I guess you would call it freshwater. **Q: Does this kit work for saltwater?** A: According to the product label, it works for marine(saltwater). I have only used it for fresh water, so cannot comment on effectiveness in saltwater. **Q: Will this work for testing a lake?** A: I’ve used it for testing freshwater streams, lakes, and canals. I’ve seen range of 5-16 mg/L. You’ll want to take measurement as soon as possible. ## Customer Reviews ### ⭐⭐⭐⭐⭐ easy to use and has worked every time except the ... *by M***. on August 1, 2017* easy to use and has worked every time except the first time I tried to use it, the water stayed clear, so I think I did something wrong.

I thought the oxygen was probably OK based on the filtration I was using, and this test confirmed that it was fine. It was only a little more complicated than other liquid aquarium test kits, so if you've done the nitrate test with the multiple chemicals where you have to shake the bottles and wait 1 minute here and 5 minutes there, this should be easy for you. It was a LOT easier to read than other kits I've used for water testing, probably because this one comes with a little cup instead of the skinny tube that comes in most kits. I was skeptical based on some of the reviews, but after using it I have nothing negative to say and I would definitely recommend it. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/120154724-salifert-dissolved-oxygen-test-kit](https://www.desertcart.co.uk/products/120154724-salifert-dissolved-oxygen-test-kit) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-18*
