This is my favorite place for pool supplies. Their staff is very knowledgable. I just had my 30 yr old pool filter die on me so I went and researched filters and decided on the brand I wanted but was not sure of the size I needed. So I went to several places and found them trying to sell me their most expensive one and installation. With their prices in hand I went to pool supply warehouse and asked them what filter I needed. They asked me several questions about the size of my pool, whether it was in or above ground, the HP of my pump and the tipe of pool cleaner I had. When all was said and done they explained what filter size I needed, why I needed it, how to install it and saved me $350 dollars on the project. I highly recomend them.
