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.
