## Questions & Answers

**Q: I have a vinal pool with 2700 gal of water. Will this kit work for me?**
A: Great question.  HTH Pool Care Green to Blue Advanced is a great product but it is ONLY for swimming pools that have the capability to "VACUUM TO WASTE" which means bypassing the filter.  Generally, pools that use a cartridge filter do not have this capability and that is usually the case for smaller pools like yours.  Just to clarify, Green to Blue is a "system" which includes 4 packs of shock and 2 packs of flocculant.  It's the flocculant that would cause some trouble if not able to vacuum to waste.  The floc causes all the dead debris to drop to the floor of the pool, and then needs to be vacuumed to waste.  So please make sure about the "vacuum to waste" part before using this product.  IF you have other questions or need assistance, please feel free to reach out to our Consumer Engagement Team at 866-484-7665. We're Here To Help, M-F, 9 AM - 7 PM (ET).

**Q: Does this new package of green to blue only come with 1 pack of each? The old package we use to buy had 3 of each in it.**
A: Thanks for this question.  As the manufacturer of this product, this kit should come with 4 bags of shock and 2 bags of flocculant. Total 6 bags.
If you did not receive it with all contents, please contact the vendor/seller for a refund and replacement.

**Q: Do I have to buy two boxes for pool with 25000 gals**
A: We are the manufacturers of HTH® Pool Care Green to Blue Advanced Shock System. One box treats a pool up to 20,000 gallons of water. So for 25,000 gallons you would use one entire box and part of another box, so 2 kits would be best. If you have questions about this system, please let us know at 866-484-7665.

**Q: Max time to vacume ? Can you wait longer then 24 hour?**
A: We are the manufacturer of HTH® Pool Care Green to Blue Advanced, when using this product, it may take 12- 24 hours for the step 2, flocculant, to settle to the bottom of the pool. We recommend vacuuming it to waste as soon as possible. Also, before using make sure your filter has a waste setting so you can vacuum out the residue without going through the filter media, residue and water go out the backwash hose. To find out if this product is right for you just give us a call, 866-484-7665.
