## Questions & Answers

**Q: Can I use this in a pool that my dog swims in?**
A: To be safe  l wouldn't recommend it

**Q: Can this be added to the pool if the water has started to turn green but not slimey or does it only work when added in first instance please?**
A: I added it to cover the winter period so not sure but sound like you need a shock treatment to kill the algaecide first.  Quite a few available on amazon but I always add sodium hydrochlorate.

**Q: Can I use this in a hot tub?**
A: Not sure check with pool providers

**Q: Can you go in pool with this in**
A: Yes, definitely...no problem. This keeps the pool clean and is perfectly safe.
