Like many other customers I received very old inventory that is about to expire, and the Phosphate A solution leaked all over everything. This reagent is labeled Danger, contains Sulfuric Acid, and it even dissolved parts of the instructions. The real puzzling part is when I performed the phosphate test with the remaining solution the results were zero when I know my current level, and confirmed my current level is around 0.100 ppm. This is really concerning as I dose phosphate, and I could of easily overdosed my reef based on this inaccurate reading if I didn't cross check the results.To be clear, this Red Sea kit is a very good, sensitive, and accurate test when the kit is fresh, and the reagents are not compromised. I use this kit all time time, and this purchase was to replace my phosphate reagents that are running out.With COVID and stuff, it's just not worth the trouble of returning it, so I will just suck it up and accept that I got ripped off. Please don't make the same mistake.

Great test kit, quick and easy to use. I have the Hanna for PO4 but it is a pain to keep viles clean and tap the powder in. RS PO4 test gave same reading as the Hanna with less hassle and cheaper! NO3 test is quick and accurate.

Everything came in box nice and packaged. Amazon did their part in making sure item was secure in the box. All products in box dont expire till 07/20 so everything is legit will definitely recommend this product to anyone who needs to check their phosphates in their tank.Also nothing was leaking or broken as you can see in my picture. All seals were in tact of the bottles

Many say that this is complex to use, but I find it very simple. NO3 is 5 drops of liquid, 1 scoop of part B, and 1 scoop of part C. Wait 9 minutes and use the wheel for an accurate measurement. NO3 is as accurate as 0.25ppm. PO4 is just two part: 10 drops of liquid and 4 drops of another. Wait 15 minutes and use the wheel for an accurate measurement. PO4 is accurate up to 0.02ppm.Will purchase this product again.

Great test kit but first one I ordered was damaged and had to send it back for a replacement

This is my first experience with a Red Sea test kit, and I'm pleased. Trying to compare colors of test samples with the provided color code cards, is always challenging. Red Sea's color wheel comparator make it easier and instills greater confidence that I am deciphering the results correctly. The ability to do both high and low level testing is great, and the multi-test kit is a good value over buying these tests individually. It's a well thought out, premium product.

Wow, for forty something bucks you sure get a lot of stuff in these Red Seas test kits. There are a couple of youtube video reviews that basically demonstrate the methods of test using the color wheel. One set of titrate chemicals for each test. Nitrates and Phosphates you just flip the cd like disk over.To note in particular using the nitrate test, this kit zero's in more exact of the level of nitrate in the lower ranges. By that I mean to say that the color comparison is easier to distinguish than the lesser expensive API test kit color sheet. Not that it make that much difference if you step back a second and look at the bigger picture. In perspective, you either have nitrates or you don't.If you do then it really don't matter so much how little or how much! You just know that you need to eliminate them from the tank environment as soon as possible for the sake of the fish and the corals. So both the API and the Red Sea kits are good as the other with respect to relative indicators of nitrates.The Phosphate test is what sets this test kit apart from the basic API test kit (Ammonia, Nitrites, Nitrates) and where this kit gets it's name Algae Control since the basic API kit don't include a test for Phosphates. The instructions sheet discusses methods and products to use in order to eliminate one or both of the components used for algae to form. Even if your running a skimmer to separate Phosphates from the water. All in all this test kit was well worth the money.

Simple to use, color wheel makes it easy to read results. Photos shows No3 reagent B& C as liquids I received both as powder reagents, not really a big deal but just pointing it out.Up-date, this info is for the NO3 reagents."The NO3 reagents were changed due to legislative changes in some markets, which prevented the use of one of the chemicals. We had been aware of the need to develop a test kit which was going to comply with incoming regulations (I am not sure if they apply to the USA as this is not where I am based, but we obviously produce one kit for global use and the changes were required elsewhere). The new kit is very precise and as with all our kits the manual must be followed very closely, including the timings and when to shake or not shake reagents vigorously."
