Kari Anne –
Should have been included in the larger kit
Itâs a test kit. Wish it was included with the larger kit I ordered since phosphates is an important parameter to monitor. Instead I had to spend an extra $24.99 for it. But it is easy to use and read.

Tough to read at low levels
Overall good product for the price but would recommend a colorimeter instead of this.
Laura –
Great product, poor delivery
The Red Sea phosphate test is very easy to perform. The results are very clear and easy to read. I would give this product 5 stars except that my package was a day late and the product leaked in the box!

Garbage
Got my test kit today and it looks like it was dragged through the dirt. Dirty box and leaking bottles on the inside. The cap wasnât even on tight in the bag!
