This turned my pool that was a light green to a very dark disgusting green.

reply from HTH Pools Team
Hi Debbie, thank you for sharing your feedback. If your pool water was a clear light green that darkened after adding shock, it's very likely that you have metals in the water that reacted to the shock. This reaction is easily reversible with the use of a metal sequestering product like HTH Pool Care Metal Stain and Scale Control. Please give us a call or chat so we can help you get your pool clean and clear! You can reach us at 866-484-7665 or chat with us at hthpools.com. We're Here to Help!
