Easy to use. But there's a chemical smell, other than that everything is satisfactory ### ⭐⭐⭐⭐ Great work done by these tablets *by A***H on 19 January 2024* It's a great little product, I was skeptical before buying but I have used 8-10 for my 5000 liter underground water tank, works like a charm. The water smells fresh and although there is a very mild smell of chlorine it's nothing that could ruin your experience. Overall would recommend. ### ⭐⭐⭐⭐⭐ HEALTH BENEFIT *by S***R on 1 September 2024* Usage of these chlorine tablets are recommended if your water contains sediments and an RO is not a great option. I use it for my rooftop water tank and drinking water filter. The package indicates that 1 tablet is to be used for 500 ltrs and it is recommended to use 2 tablets for a 1000 ltr tank. Too much chlorine in the water can lead to hairfall so it is recommended to use as mentioned in the package. Best season to use is Monsoon when water contamination can lead to stomach infections, jaundice, and other gastro intestinal problems. The tablets are soluble so it is easy to use. The quality of the product is great. ## Frequently Bought Together - Ef-Chlor 4gm Overhead & Underground Tank Water Purification Tablets - Combo Pack of 2 Jars (40 Tablets) | Purify 40000L of Water | 1 Tablet Purifies 1000L Water | Reliable Water Treatment Solution - Ef-Chlor 8.5 mg Water Purification Tablets (100 Tablets) – Compact, Fast-Acting, and Reliable Solution for Safe Drinking Water in Emergencies, Travel, Hiking, Camping, and Outdoor Adventures - Ef-Chlor 17mg Water Purification Tablets (100 Tablets) – Effective Water Treatment for 3-4L, Ideal for Camping, Hiking, Backpacking, Travel, Survival, Emergency Preparedness, and Outdoor Exploration --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ma/products/85532921-4gm-overhead-and-underground-tank-water-purification-tablets-combo-pack](https://www.desertcart.ma/products/85532921-4gm-overhead-and-underground-tank-water-purification-tablets-combo-pack) --- *Product available on Desertcart Morocco* *Store origin: MA* *Last updated: 2026-04-22*
