Items needed to fix your clear blue pool water:

Mega Maintain Metal, Stain & Scale Control is a sequestering/chelating agent that holds stain-causing metals, like iron, copper, and manganese in suspension.

Rust and Iron Stain Remover reduces the suspended oxidized iron (rust) into its clear ionic form.

Copper Stain Remover reduces the suspended oxidized copper into its clear ionic form.

CuLator Ultra 4.0 removes and eliminates dissolved iron and other metals from the swimming pool.

Purchase the Stain Eliminator Kit and use the step-by-step instructions below to solve your blue pool water problems!

Prior to starting this procedure read all instructions. Make sure to properly balance the pool and spa water, but the free chlorine level should be below 0.5 ppm. IMPORTANT: The pool should not be used until the procedure is completed and the pH is 7.2-7.8 and free chlorine level is between 1.0 ppm and 4.0 ppm.

Balanced Pool Water Guide: Free Chlorine: 1-4 ppm, Total Chlorine 1-4 ppm, Combined Chlorine 0, pH: 7.2-7.8, Calcium Hardness: 200-400 ppm, Alkalinity: 80-120 ppm, Cyanuric Acid (CYA) 30-50, Iron: 0 ppm, and Copper: 0 ppm.

Step 1.

First, balance the swimming pool water and wait for the chlorine level to go below 0.5 ppm. This may take a several days.

Step 2.

Walk around the edge of the pool adding 1 quart of Mega Maintain Metal, Stain & Scale Control

Step 3.

Walk around the edge of the pool adding 1 bag of Rust and Iron Stain Remover and 1 bag of Copper Stain Remover. This will both reduce the chlorine level to 0 ppm and help to remove the blue or other color of the water.

Step 4.

Place the CuLator Ultra 4.0 into the pump basket. Run the circulation pump for 2 hours.

Step 5.

When the water is clear and colorless, start to slowly add chlorine (1/8 of a lb. of powdered chlorine or 1/4 gal. of liquid chlorine per hour, per 20,000 gal.) until the level reaches 1-4 ppm.  The pool water may go cloudy*, which is normal, and may last a few days to several days. It may take a large amount of chlorine before the chlorine holds. Finish balancing the pool water and maintain a chlorine level between 1-4 ppm.

Important: After 12 hours, even if the water still has color, you MUST start to add chlorine until it holds at 1-4 ppm to avoid an algae bloom. Slowly add chlorine (liquid chlorine is preferred) to the pool. If you are using “pool shock” to add chlorine to the water, add no more than 1/8 of a 1 lb. per hour. If you over-chlorinate the pool, you risk staining your pool surface.  Follow all steps for best results.

Keep the chlorine level between 1-2 ppm for 3-4 weeks. DO NOT OVER-CHLORINATE WITH LIQUID OR POWDERED CHLORINE OR SHOCK DURING THIS TIME. (If you allow the chlorine level to exceed 4 ppm the brown water may return and surface staining may appear). Keep the filtration system running for a minimum of 12 hours per day until the water is clear. 

*Note: The pool water may temporarily turn cloudy due to the chlorine removing excess Stain Removers. Once the excess Stain Removers are gone, the cloudiness will disappear, and you will be able to hold and measure chlorine in the pool water.  This may take several days.
