Super easy! - Works great! Dip in water, add items for colors that dont match those in boxes. Turns jets on and wait 10-15 seconds to re-test. Colors for those items you added are now in the boxes! Easy peasy! Review: Salt Water - Simple, effective(ish), and easy - I have a small 18' above-ground salt water pool, and although it came with test strips, they were USELESS. So I was told test strips for salt pools are not accurate, but after reading the reviews, I figured I would give it a try. I had other devices to test my water but I wanted something quick and easy to use to give me a "feel" of where my water readings were. These actually did rather well although there were a few readings off that could have been better but it did help me maintain the levels across the pool a bit easier. Simple dip for a couple seconds and wait a bit for the strips to turn. Match it up with the bottle and run from there. It beats chemicals and lots of tools but same time it doesn't exactly replace those items either for accuracy. Would I buy them again? Yes! ## Features - CHECK WATER HARDNESS: This handy water hardness test kit allows you to test the hardness of all water sources, from home faucets and taps, to well water, water softeners, dishwashers, showers, aquariums, and many more - MULTIPLE USES: The right levels of water hardness can make a huge difference in the softness of your laundry.

Yes! ### ⭐⭐⭐⭐ Just what I needed. *by M***. on March 10, 2026* These test strips are great. You get the results very quickly. The color change is very obvious and very easy to use. I would not recommend it to test your salt levels as I don't really get a good reading. It always says it is low. All the other tests come out right. Great value for the money. I would try it out and get your salt levels checked from you salt cell or Pinch a Penny. ## Frequently Bought Together - 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 - Bestprod All-New 20 in 1 Drinking Water Testing Kit 120 Strips, Home Tap and Well Water Test Kit for Hardness, Lead, Iron, Copper, Chlorine, Fluoride - 2024 All-New 4 in 1 Tds Meter Digital Water Tester - Accurate and Reliable TDS EC & Temp(Β°C,Β°F) Meter - 0-9990ppm - Professional Testing for Drinking Water, RO/DI System, Aquariums etc --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/61520114-water-hardness-test-kit-quick-and-accurate-water-hardness-test](https://www.desertcart.gr/products/61520114-water-hardness-test-kit-quick-and-accurate-water-hardness-test) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-05-29*
