API NITRITE TEST KIT 180-Test Freshwater and Saltwater Aquarium Test Kit

Great

Test seems to work, showed varying levels as new tank was cycled. The small glass tube warped somehow when I didnt empty the solution. Either chemical reaction or from too much exposure to sunlight on window sill? I dont know but it crumbled into small shards. Pretty annoying.

Green aqua = 0 ppm Blue warns and purples shout.

I test my aquarium at least twice a day....this kit makes it so easy and I feel like a mad scientist when I test the water.

Being new to fish tank keeping after all these years I had to order all of my supplies. This test is easy to use and many many tests in the box. The ONLY downfall to these is honestly the company should re think the shape of these tubes. I can’t tell you how many times they have tipped over lol too tall and slender makes them tip easy

I dont like the packing for products

excellent

Fantastic trade! arrived super swiftly :)

A must have for any aquarium!

Kit works well.
