Phosphorus and Phosphate Detection Test Strips, 0-100 ppm [Vial of 50 Strips]

Ineffective at measuring aquarium phosphate levels. Not even close to a granular enough measurement.

Every one should tests phosphate levels of water whether it is for livestock, drinking or showering. You should also test often as water changes drastically due to neighbors overuse of pesticides. Please stop P ing in our aquifers. This lets you know whether your reverse osmosis or other flirtation system is working. If you use strips and now know you have issues it does not matter which color it turned, u need to correct problem and test again. Once you have under control and are below the threshold cut off of these strips (meaning no color change) them send to lab to see if your are at zero. I don't need anymore phosphorus as phosphate used in EVERY single packaged food from crackers to McDonald's so even though I don't eat meat I have plenty of phosphorus intake as even in prescription medication. We are being poisoned with the level of phophorus and many doctors will tell you maybe you have kidney disease but it will just be the ridiculous amount if phophorus your are intaking.

Excelente para un análisis rápido de la calidad del agua!!

Simple, gives your results in 3 minutes. Using for 15,000 gallon pool. Only comes with 50 strips, but once your phosphate is under control, it's not something you need to test every week. Just primarily in spring and fall when debris falls into your pool.

These strips are not accurate with experience. It could be that I use bromine as a sanitizer in my pool, so they may work as intended for other applications. Also, the strips came packaged with the test pad end at the top of the container, so you end up touching the pad and possibly contaminating it!
