My other half and myself just bought a home with a pool. We were using another pool supply store. We had a huge problem with yellow algae. The other store kept selling us all of these expensive chemicals and nothing was working! I go to Pinch a Penny and they sold us exactly what we needed. It's been less than 24 hours and the pool is blue again! Pinch a Penny and there employees are outstanding! We will be doing all of our business from here on out with this amazing business.
