## Questions & Answers

**Q: Can I use this in an in ground vinyl lined pool? I am concerned it may damage the vinyl liner.**
A: I use it in two different vinyl pools. These are not inground but they are common $500 pools and one of them is actually a hot tub. Absolutely zero stains. This product works great. I'm not totally sure but I'm pretty sure the only thing that's going to stay in your pool is if you leave chlorine tablet on the floor. I did exactly that once by mistake and that chlorine tablet left a 2 ft size white mark. So be careful with your chlorine and that's really it.

**Q: Do you use this before/after or with the Chlorinating tablets?**
A: Hi, We are the manufacturer of Clorox Pool and Spa products. Chlorinating tablets should be used in order to maintain a 1-4ppm residual in the pool. Our shock products are meant to boost the chlorine level to oxidize material that accumulates over time like oils, greases, algae, bacteria, etc. If you're setting up a pool or are trying to clear cloudy water from over the winter, then you can add the shock before having tablets in the pool to eliminate any contaminates that may have accumulated. However, once the pool is crystal clear, then the shock can be added on a weekly basis (with tablets in the pool) to maintain clarity and to prevent contaminate accumulations. If you have any other questions or concerns, please give us a call at 1-800-SOS-POOL.

**Q: Can you use it on vinyl pools**
A: Yes this is the only product I use in my above ground pool and works perfect. No discoloration of pool liner

**Q: Can i use this instead of clorox shock for small pools? the clorox app recommended the latter, but i can't find it in my area.**
A: This is the Clorox shock for small pools this is just the better version in my opinion. I have an index pool and it works fantastic. I use half then wait 24 hrs and test again. Half normally does just fine sometimes I have to add the other half.
