There's a ton of sand along the bottom of the spa. Is it possible to drain an in ground outdoor spa? What's the best way to clean the spa? It is a gray color, while the pool is clear and blue.
Hi all, I am a new pool owner. Recently, I got my chemicals checked and I noticed that my pool has 100ppm CYA. What should I do? Also, does this mean I need to keep the FC levels higher in order for the pool to be safe to swim in? Its currently around 7 ppm FC.
