NYOS® REEFER test kits - taking measurements at the laboratory level at an attractive price
Water properties as close to nature are the key for every aquarium's success. However, monitoring relevant parameters in seawater is difficult due to numerous interfering ions. Therefore, test kits considering the specific characteristics of seawater are needed to analyze the water precisely.
NYOS® REEFER test kits offer the customer two significant benefits:
Highly precise analyses for seawater conditions. Furthermore, they offer a highly attractive price-performance ration and make test kits in laboratory quality affordable for the standard hobby user.
Additional characteristics of our REEFER test kits:
- calibrated dropper made by a German manufacturer ensures uniform drops during all repeat tests
- reagents are made in Germany in accordance with EN ISO 9001
- reagents are analyzed according to AAS and NIST standards
- strict batch and quality control
- easy to use with intuitive pictogram instructions
- Made in Germany
NYOS® REEFER test kits allows you to achieve precise and most importantly reproducible (i.e. in repeat measurements identical) measuring results.
dropper is terrible By Preston on 7/25/2019Preston wouldn't recommend this product to a friendThe dropper is terrible it either dumps out 50 drops in a tenth of a second or it doesn't want to produce any drops at all. It ends up wasting a bunch of reagent, pretty disappointing.
Great unless you’re over 12+ NO3 By Reefahholic on 3/9/2019Reefahholic would recommend this product to a friendIt’s great on the low end, but after 12 it’s complete garbage. Colors aren’t even close.
Easy to read By Mikel on 11/28/2018Mikel would recommend this product to a friendI really like how simple this kit is to read. Much simpler than trying to match color to a card without a reference, I really prefer comparing the two vials. My girlfriend is color blind and even she can tell where the colors match up with this kit.
So easy By Carl on 9/22/2018Carl would recommend this product to a friendPurchased this kit because of others reviews and I also confirm: the dual color chart and vial holder works incredibly well. I am "color confused" sometimes as my grandfather was color blind. I feel 100% confident that I can differentiate and trust my findings. Priced right for what you get. I'm very happy with it.
Easy to use and helps determine lower Nitrate levels By Bill on 6/19/2018Bill would recommend this product to a friendLike many of us, Inused another test kit that only showed that my nitrates were under 5ppm. I desired a more accurate reading and found that with this kit. The kit is simple and relatively quick to use. The colors are easier for me to discern than others. One bit of advice when using this kit for the first time: The cuvette holding the tank water WITHOUT reagents is the one you place on the colored mat. I read the instructions and missed this and thought I had a faulty kit, but after re-reading them, I realized my mistake.
Very Easy to Read By Sean on 6/17/2018Sean would recommend this product to a friendI echo most other comments about the Nyos Nitrate test. This is easier to use and the dual vial test helps to make for better interpretation of the results. This will be my go-to test kit going forward.
Easiest To Read By Dick on 5/31/2018Dick would recommend this product to a friendOver the years I have tried several nitrate test kits, including API and Red Sea. Based upon the BRS recommendation and user reviews, I switched to the NYOS test over a year ago. (I'm about to start on my third kit.) It is easy to use, and the color scale is by far the easiest to interpret. Until something better comes along, this is my nitrate test kit.
Excellent By Donald on 3/10/2018Donald would recommend this product to a friendEasy to use and easy to read. Best I have used so far.
Quick and easy to read By AJs Reef on 2/1/2018AJs Reef would recommend this product to a friendI've used many test kits on the market and for the past few years I've been using the Red Sea Nitrate Pro. It works well but results are slow and interpreting the color differences is difficult to say the least. Recent trends in reef keeping have SPS tanks chasing 1-5ppm these days so I figured why bother with the low range confusion. This kit reads 0-1-3-5ppm and so on. I still read 0ppm with this test but the ability to distinguish 1-5ppm has me confident to does up to 1-3ppm.
easy to use. By jason on 12/15/2017jason would recommend this product to a friendWorks as described.
Be Careful, inspect your reagent powder upon opening By BH750 on 7/3/2017BH750 would recommend this product to a friendI purchased this based on the BRS video on test kits. I really wanted to know my NO3 readings. So upon getting the kit I tested almost daily. Readings were always low (3-5ppm) and consistently. . I was happy b/c NO3 were stable. After awhile the reagents ran out so I recently ordered another one. I immediately noticed the reagent powder in the new kit looked different. Its really white (more like expected) while the reagent powder in the kit purchased in March was tan/brown. My N03 tests using the new kit are now completely different. NO3 is way higher (12-15) and kinda what I expected. I did parallel tests with the old reagent powder and still low (3-5ppm). So the reagent powder seemed to be bad in the first kit. And I used it to get incorrect readings and guidance for months! Very disappointing since you have to put so much trust into these kits and I bought it based on BRS endorsement. I still like the kit and will do a new review after using the new powder. Just check the powder and make sure it looks white.
Highly recommended, be careful with lids! By Michael on 3/25/2017Michael would recommend this product to a friendI really like this test kit. It's easy to use, far more accurate than some other brands. Another reviewer mentioned the warning about caps. The lid for your test vial is the same lid as for the regent. If you're not careful, you might put a damp lid on the regent and ruin your kit. So watch out for out, but I'm definitely buying another one when the time comes.
