The people at G&S are very helpful and do not make you feel uncomfortable asking any questions. They went out of their way to help a new pool owner, me close my pool last year and open it this year. Much better than my previous experience with the place I purchased the pool from. I have a new system on my filter and they went out of their way to help me figure out the chemicals I needed. They had no previous experience with it but it did not stop them from helping me. I highly recommend using them for all your pool supplies, water testing, opening and closing needs. The prices are fair. I will not go anywhere else.
