Quick and Easy, Low Cost By Brad on 1/1/2016Brad would recommend this product to a friendThis is as easy as it gets, (read all directions before using) slowly add up to 1ml to 10ml of water and when the reagent changes color you've got your results. Many tests per bottle.
I'm happy with it. By Dave on 6/19/2015Dave would recommend this product to a friendThe color changes abruptly, enabling you to make accurate measurements.
Consistent and accurate By Sean on 5/12/2015Sean would recommend this product to a friendI've been using Red Sea test kits for a few years now. They have been consistent and accurate so far. Really like being able to buy refills.
Excellent By Andre on 3/16/2015Andre would recommend this product to a friendThe fact you can use a test kit that repeats time after time and purchase reagent refills is just awesome in my book.
Thanks Red Sea
EASE OF USE & ECONOMICAL By DavidC on 2/6/2015DavidC would recommend this product to a friendThis test kit is easy to use and reliable and unlike other kits you don't have to purchase the entire kit once you run out of reagent. You just pay for the reagent
Easy to use By cramsmith on 2/5/2015cramsmith would recommend this product to a friendTook a while to get used to reading the color change but once you get the hang of it, it is very easy to use.
Accurate and only 1 reactant By Tek on 11/25/2014Tek would recommend this product to a friendAccurate and quick test. Great value refills as opposed to buying new kits each time.
Love This By Chris on 5/8/2014Chris would recommend this product to a friendLove being about to purchase a refill on reagents inside of puchasing an entire new kit.
I've noticed as the Red Sea Alk test reagents gets over a year old, the colors compared to the examples on the testing instructions will start to get dull, this makes them harder to read the "end" values, leaving the results up to interpretation. Purchasing new reagents will get them back to the bright red/blue and easy to read as they originally were.
The price is right on these for the value. IMO Red Sea are the best test options in the "mid teir" price level before you start getting into hanna checkers etc.
Great that you can refill By Ryan on 8/22/2013Ryan would recommend this product to a friendI think it's great that they offer a refill kit vs. having to purchase the entire kit. works great and is easy to use.
Good By Parker on 6/30/2013Parker would recommend this product to a friendSweet product. Makes it so I do not have to go out and buy another whole test kit and can save some cash to spend on other of my reefing needs.
Sweet idea and the Red Sea kit is accurate I was using salifert prior and can't recall the difference really. Red Sea has definitely stepped it up a notch
