POOL SALT 25KG (GAUTENG ONLY)

Product Description:

This high-quality swimming pool salt, containing sodium chloride, is suitable for use with salt chlorinators. The amount of salt required depends on various factors, including rainfall, pool usage, and backwashing frequency. Regular cleaning of chlorine generator cells is essential to prevent calcification and corrosion, ensuring adequate chlorine production.

Size: 25 kg

Application Instructions:

Step 1: Determine the necessary salt level for your pool, consulting the chlorinator’s owner’s manual.

Step 2: Measure the current salt level using a salt water test strip.

Step 3: Refer to “How much salt should I use?” in the FAQs below for recommended salt quantities.

Step 4: Before adding salt, turn off the chlorinator at the control unit. Keep the pump on to circulate water and aid salt dissolution.

Step 5: Avoid pouring salt directly into the pool weir. Instead, place the salt in the shallow end, avoiding direct contact with the pool lining. Allow up to 24 hours for complete dissolution. Once dissolved, remove any floating bags and related equipment.

Step 6: After the salt has dissolved, reactivate the chlorinator and check for a salt level around 3,500 PPM. Avoid exceeding 4,500 PPM to prevent reducing the life of the electrolytic cell.

Note: If you estimate needing 10 bags, add only 9 initially. After dissolution, retest the salt level before adding the final bag.

Optimum/Ideal Pool Water Conditions:

• Free Chlorine: 2.0 – 3.0 PPM (above 3.0 PPM may corrode pool metals)
• pH: 7.2 – 7.6
• Chlorine Stabiliser: 50 – 75 PPM
• Total Alkalinity: 80 – 120 PPM
• Calcium Hardness: 150 – 250 PPM
• Metals (Copper, Iron, Manganese): None
• Nitrates: None

Salt Type: Use sodium chloride without anti-caking or free-flowing agents. Avoid iodated salt, agricultural use salt, or calcium/potassium chloride.

Salt Quantity:

• 4000 to 6000 PPM depending on chlorinator make/design.
• Low Concentration: Below 2000 PPM is ineffective.
• High Concentration: Above 6000 PPM may cause corrosion.

Pool Size Chart: (Salt needed for 4000, 5000, and 6000 PPM provided for various pool sizes)

Determining Pool Size:

• Rectangular or Square Pool: Volume = Length x Breadth x Depth
• Circular Pool: Volume = (πR²) x Depth
• Oval Pool with Straight Sides: Volume = (πR²)D + (2R x H)D

Staining Causes and Treatment:

• Iron/Manganese Stains: Yellow-brown (iron) or brown-black (manganese), often from borehole water or low pH/TA levels.
• Copper Stains: Blue-black, from copper-based products or copper ionisers.
• Algae/Plant Debris: Grey (algae) or slimy brown (tannin from leaves).
• Low pH/TA: Green water, corroding pool metals.
• High pH/TA: Precipitation and scaling.
