Frequently Asked Questions
Q: What types of algae does Poolife™ AlgaeKill™ II treat?
A: It works on green, black and mustard algae, helping prevent regrowth with regular use.
Q: Will this stain my pool?
A: No. When used as directed and properly diluted, the chelated copper formula minimizes staining risk.
Q: Is it safe to swim after application?
A: Yes. There is no waiting time — you can swim immediately after applying the product.
Q: Can I use this with my saltwater pool?
A: Yes. It is compatible with saltwater systems and all other sanitization methods.
Q: Can I use this product at the same time as shocking the pool?
