But, it takes a bit more time to dissolve into water. You must dilute it before pouring into the pool.

4. Non-chlorine shock

Do you have a busy schedule? For this, you can’t wait 8 hours before swimming? If it’s yes, this product is absolutely for you!

Actually, if you have to swim within 15-20 minutes and don’t have time to leave the pool for a long time, it’s the best option. You can directly add it to the pool water and safely swim after 15-20 minutes.
