## Customer Reviews

### ⭐ 







  
  
    This is not the NYOS kit!
  

*by F***Y on Reviewed in the United States on May 24, 2021*

CAVEAT EMPTOR! I ordered a NYOS phosphate test kit, but what arrived was an AquaForest kit.  This is a cheaper kit in both senses.  It normally sells for a couple of dollars less than NYOS, uses a crystallized reagent that tends to clump making it hard to get the tiny amounts correct, has a cheap plastic test vial instead of glass and the colors on the color chart are virtually inseparable even if you manage to find a readable bit of blue in the vial. The optical characteristics of the vial cause shadows and bright spots on the bottom that make comparison with the color chart impossible no matter what light you try to read it in.  Don't waste your money; make certain you get the NYOS kit (assuming that's what you ordered).

### ⭐⭐⭐⭐⭐ 







  
  
    Very easy to read
  

*by L***E on Reviewed in the United States on October 10, 2021*

Very easy to read compared to the API test kit except the low reading only goes down to 0 and is only read in whole numbers. Got those needed a reading lower than 0 you need a different kit.

### ⭐⭐⭐⭐ 







  
  
    Hard to differentiate results below .1
  

*by R***I on Reviewed in the United States on April 25, 2019*

Made of quality elements. Read and follow instructions carefully inside the manual and not the one at the back page. The results are hard to distinguish below 0.1 so I used a magnifying lens under a bright light. I'm guessing it's because phosphate levels below 0.1 are insignificant already. My conclusion is that the closer to white1/white2, the better.
