## Description

desertcart.com : Water Hardness Test Kit - Quick and Accurate Water Hardness Test Strips - Hard Water Test Kit with eBook - Ultimate Test Kit for Water Hardness - 150 Water Softener Test Strips by JNW Direct : Patio, Lawn & Garden

Review: Accurate, Fast, and Easy to Use — Great Value! - These test strips work perfectly and give quick, clear results. I used them to check the hardness of my tap water and my softener system — both readings were accurate and easy to interpret thanks to the color chart. The included eBook is a nice touch, explaining water hardness and maintenance tips in simple terms. With 150 strips, it’s an excellent value for ongoing testing.
Review: Great product, great price! - These strips are very easy to use and the results are easy, straightforward to read. You do have to work very quickly for accurate results but after using them a few times you’ll get a routine down and have no issues. They offer a free ebook/manual that provides very detailed instructions as well as descriptions of each chemical, the dangers of having too little/too much of it in your pool/spa and how to correct & maintain proper levels. You’re able to print this ebook right from their website as a PDF. Ordered these strips after clearing up algae that left us with insane cloudiness afterwards that we couldn’t clear no matter what we tried. Spent a few hundred dollars at our local pool store on all their recommended chemicals that didn’t work. Took in multiple water samples for them to tell us everything was perfectly within normal range but “here use this, it’ll clear ya right up”. These strips immediately showed us our chlorine & bromine levels were off the charts too high, alkalinity way too low. Once correcting those levels we’re slowly getting back to crystal clear water. I highly recommend these strips, we’ve added these as a product to purchase yearly for our very short Northeast Ohio pool seasons.
