Yellow Out is the perfect algae solution for a extremely green pool.
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 is not affected by higher levels of cyanuric acid.
