Coral Seas Yellow Out Swimming Pool Chlorine Shock Enhancing Treatment

Compatible with pools operating a chlorine generator Simple to use, requires no brushing, and cleans up algae gently without the use of harsh chemicals Used in conjunction with pool shock to safely remove green, yellow, brown, and pink algae from your pool Safe, non-toxic and can be used on all pool surfaces, including vinyl liners Use 2 lbs of Yellow Out per 15,000 gallons of water prior to shock treatment with an EPA-registered chlorine that kills yellow algae. 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.
