    Simplest Phosphate Tester

    Posted by Alyxandria on Mar 5th 2015

    Super easy to test your phosphate levels. No confusing and t"oo similar" colours - when read under the right lighting you know what your phosphate readings are immediately. I love this product and when my current one runs out I would buy another one. Good product.
