Coral Seas - Yellow Out Pool Sanitizer

The Coral Seas Yellow Out is a pool sanitizer that achieves algae clean-up quickly and efficiently. Simply run your filter for 24 hours after adding to keep your swimming pool clear, reduce algaecides and eliminate stains without brushing. Use 2lbs of Yellow Out per 15,000 gallons of water.

Yellow Out works great for all pools, including those with salt chlorine generators and plaster finishes. Both of these circumstances can create a higher pH in pool water (especially newer plaster), which happens to be the ideal condition in which Coral Seas products work. The recommended pH level is 7.8 or higher for ideal performance. This is opposite of traditional algae treatment methods which require a lower pH for chlorine to be more efficient. Yellow Out are also not affected by higher levels of cyanuric acid.
