Awesome kit! By Erik on 3/29/2016

This is an awesome test kit, once you get the hang of how to perform the tests, seems complicated but it is not. Pretty accurate and keeps my reef happy! Only thing I don't like is, it's hard to get everything to fit back into the black box once you take it out!

Very easy to use test kit. Also the price is great compared to buying each test kitCRESTWOOD individually.
Magnesium test doesn't work By Brian on 3/25/2016
Brian wouldn't recommend this product to a friend
Been reefing for over 3 years now, and I got this product based on BRS recommendation. I like the titrator, but test results are very inaccurate. I do not dose magnesium at all, so there is zero reason as to why my magnesium levels should be any higher than my salt mix (I use reef crystals) but EVERY time I have tested with this kit my magnesium reads 1600 ppm. That is absolutely impossible, magnesium doesn't form out of nowhere in the home aquarium. I can see ALK and calcium levels differing due to many different factors, but not magnesium. Beyond frustrated. Wish I would have just spent the extra $70 and got Hanna checkers for all of these.
Bad kit By Todd C. on 3/10/2016

The alkalinity test color chart shows are dark red upon complete titration, but no matter how far you take the test, I've never seen anything but a light pink. So this test parameter (for alk) is worthless to me.

I've used API and Salifert before and this is my go-to for Mag, Cal, Alk. Very easy to do and accurate. Very well made too. I like that this is a kit, and a box that stores everything and you just buy re-fills when necessary.

when I first got it I was intimidated with everything included, but after reading and watching youtube videos it couldn't be easier
got a bad batch By Kevin on 2/16/2016

I like the quality of the test components but my Alk test is hard to read because it changes from blue to orange to yellow instead of blue to red. I contacted Red sea via email but got no response. CA and MG test work great. I wish red sea would replace my alk test but I can't get a hold of them. Will buy different test when I run out of CA and MG test solution. I have been using the Hanna Alk test and love it!
Nice kit By Paul on 2/12/2016

This is a pretty decent kit with a nice case and water resistant reference cards. Its pretty simple to use as well. My only complaint with it is that i'm not exactly sure when to take the reading as there seems to be a couple of drops where the color change happens. So i'm not sure if I take the reading just as it changed, in the middle of the change, or after it stops changing color. Of course each drop is a .2 reading so its not a huge difference in the outcome.
Great product By Jose C. on 11/14/2015

At first it was confusing. It takes time getting the correct color in the vale. But with a few practices and some patience it became easy. The videos on youtube were a great help also.
Good quality product By Daniel on 10/15/2015

Good quality product, nicely fits into a hard plastic box for storage, the cards are laminated and everything is designed to last. Everything is color coded so you use the right siringe with each test. Takes some time to do the tests, but the accuracy is worth it, good things don't come easy.
