How to Stop Iron From Staining Your Own Pool

Too much iron in your pool might appear as red, brown, black, green or gray spots on the pool walls and floor. The iron can enter the pool water from passing through corroded iron pipes and fittings connected to your pool and pump, or when you use well water to fill your pool rather than your city water supply. It is possible to mix iron stain removers with the pool water to remove the stains, but you must keep your water balanced to stop the iron from staining your pool.

Take a pool water sample to a pool supply business or use a home test kit to ascertain the pH levels, total alkalinity and calcium hardness. Follow the directions supplied with your pool water test kit to make sure you get the appropriate readings. Also check for the presence of stabilizers or seams, and also for chlorine levels in the water.

Insert sodium bicarbonate to raise the alkalinity levels or sodium bisulfate to lower the alkalinity level. The ideal choice for total alkalinity is between 80 and 120 ppm. The amount of product you include is based upon the total amount of water in your pool and the product. Insert the sum specified on the product tag to avoid moving the total alkalinity level too far in either direction.

Add sodium carbonate to the pool water for a pH level that’s reading under 7.0. Add sodium bisulfate for a pH level that’s reading above 7.0. According to PoolSupplyWorld, the perfect pH level is between 7.4 and 7.6. Follow the directions listed on the selected product for the right amount to grow your pool dependent on the number of gallons your pool holds.

Raise the calcium hardness level with the addition of calcium chloride to the water as suggested by your readings as well as the quantity of the pool. The calcium hardness should read between 200 and 400 ppm. Calcium hardness above the recommended maximum requires draining most or all of the water from the pool.

Insert cyanuric acid to condition or stabilize the pool water, which will help avoid destruction of the chlorine in the pool and also keep the water from becoming unbalanced. Continue to include cyanuric acid to the water until testing ends in a reading between 30 and 50 ppm.

Raise the chlorine in the pool to a level between 2.0 and 4.0. The amount of product you use depends upon the number of gallons your pool holds and the type of chlorine you utilize. Strictly follow the recommendations of your chlorine product to avoid over-chlorinating your own pool.
