Comments on: was given a Power Ionizer box for our pool and it says something about iron in the water. How do you test 4 it? http://alkaline-water.info/131/was-given-a-power-ionizer-box-for-our-pool-and-it-says-something-about-iron-in-the-water-how-do-you-test-4-it/ Learn How To Separate Fact From Fiction Sat, 04 Feb 2012 06:23:23 +0000 hourly 1 http://wordpress.org/?v=3.3.1 By: DB http://alkaline-water.info/131/was-given-a-power-ionizer-box-for-our-pool-and-it-says-something-about-iron-in-the-water-how-do-you-test-4-it/comment-page-1/#comment-171 DB Wed, 28 Jul 2010 17:13:03 +0000 http://alkaline-water.info/131/was-given-a-power-ionizer-box-for-our-pool-and-it-says-something-about-iron-in-the-water-how-do-you-test-4-it/#comment-171 If your water looks red or brown (or sometimes green) after adding chlorine you likely have iron. Go to your local pool supplier and ask for an iron test kit. You test it the same as chlorine and pH with a color matching test. To solve the problem of colored water as a result of metals, there are two general approaches: Shock treat the pool to oxidize the metal, which then settles out of solution and looks like rust. The rust can easily be vacuumed out of the pool. Add a sequestering or chelating agent which forms complexes with the metal and prevents it from being oxidized by the chlorine. If the source of the copper or iron cannot be established or if it cannot be avoided, regular addition of a chelating agent or sequestering agent (metal out products) will ensure that any new metal arriving in the pool water will be held in an inactive complex.
