Jack’s Magic Stain Solution #1 is a non-acidic product that’s used for removing iron, cobalt, and spot-etching stains. It can be used on all types of pool surfaces and without draining the pool. These stains are typically eliminated within 48 hours with very little need to rebalance other pool chemicals. Please remember that it is not advisable to swim while doing this treatment. You may swim after the stains have been removed and after your water chemistry is back to normal.
The recommended dosage is: 2 lbs. per 12,000 gallons.
