Yes. The formula is non‑toxic and contains no harmful phosphates, making it safe around swimmers, children and pets.
Can I use this with other pool chemicals?
Absolutely. The tablet works alongside chlorine, bromine and other standard sanitizers without interfering with their performance.
Will it affect the pool’s pH level?
No. The stain remover is pH‑neutral and will not alter the water’s balance.
