Calcium Drinking Water Minerals
Calcium Chloride DihydrateRestores calcium hardness and natural taste, and makes RO water less corrosive to pipes and tanks. Assay min. 98%.
Food-grade calcium, magnesium and sodium to put taste, hardness and alkalinity back into RO water. These are the water treatment chemicals that go in after the membrane. One price for all three: Rs 800 per kg.

Restores calcium hardness and natural taste, and makes RO water less corrosive to pipes and tanks. Assay min. 98%.

Adds magnesium for a smooth, rounded mouthfeel and balances the calcium you dose. Assay min. 99%.

Raises alkalinity and lifts the low pH of RO water into the normal drinking range. Assay 99.0–100.5%.
Most plants dose calcium and magnesium together, and many add sodium for pH. Fill one 2 kg or 5 kg box with any mix of 1 kg pouches and pay the box price, with the box saving included.
All minerals are packed in sealed, moisture-proof 1 kg pouches and boxed in 1, 2 or 5 kg. There is no minimum order, and bigger boxes cost less per kg.
| Pack | Good for | Price |
|---|---|---|
| 1 kg pouch | Trials, small plants, top-ups | Rs 800 |
| 2 kg box Save Rs 50 | Regular weekly supply | Rs 1,550 |
| 5 kg box Save Rs 200 | Larger plants and bottling lines | Rs 3,800 |
Prices are per box and the same for calcium, magnesium and sodium, including mixed boxes. Prices exclude standard delivery charges, which we confirm when we call you.
All three are dosed after the RO membrane. The right amounts depend on your raw water, your target TDS and the taste you want.
| Mineral | Compound | What it does | Watch out for |
|---|---|---|---|
| Calcium | Calcium chloride dihydrate | Adds calcium hardness, improves taste, reduces corrosiveness | Absorbs moisture: keep pouches sealed |
| Magnesium | Magnesium sulphate heptahydrate | Adds magnesium and a smoother mouthfeel | Too much can taste bitter |
| Sodium | Sodium bicarbonate | Raises alkalinity and pH so water doesn't taste sour | Small doses go a long way: increase gradually |
Send us your plant capacity and water report on WhatsApp. We'll suggest a starting mix you can fine-tune with a TDS meter (our TDS level chart shows the range to aim for). To understand the basics first, read our RO water remineralisation guide.

Calcium, magnesium and sodium minerals are all Rs 800 per kg, with savings on boxes: Rs 800 for a 1 kg pouch, Rs 1,550 for a 2 kg box and Rs 3,800 for a 5 kg box. Standard delivery charges are extra and confirmed when we call you.
No. You can order a single 1 kg pouch for a small plant or a trial, or as many boxes as your plant needs.
Confirmed orders are delivered the same day within Lahore. Orders to other cities in Pakistan usually arrive in 2 to 3 days.

Yes. Add any minerals to one order, or build a mixed 2 kg or 5 kg box with any combination of calcium, magnesium and sodium and pay the box price.
Keep packs sealed in a cool, dry place out of direct sunlight and away from heat. Calcium chloride absorbs moisture from the air, so close opened pouches tightly.
It depends on the stage. Before the membrane, most plants dose an antiscalant and remove chlorine. After the membrane, plants that remineralise add calcium chloride, magnesium sulphate and sodium bicarbonate. Our RO membrane and filters guide covers the first part, and the remineralisation guide covers the second.
No. We only sell the three food-grade minerals that are added after the RO membrane. Ask your plant supplier for antiscalant and cleaning chemicals made for your membrane.
Rs 800 per kg, less in boxes. No minimum order, same-day delivery in Lahore.
