Our previous tenants rarely, if ever, cleaned the pool. It was left looking very stained, and the water was a slimy greenish colour. Mick said I would be surprised at how well an acid wash would improve its appearance. Due to the original state of the pool, I didn’t get my hopes up…but now I have a beautiful pool with clear water, and it’s blue! Not greeny-brown like it was the day before he arrived. I plan to get Mick to check up on the pool from time to time, and would recommend Pooltastic to anybody.
