The overall experience was great. The only problem I had was when I tried to find the option of where I would like to pick up my order, it would not allow me to do so at the Surprise location. Dan, from the Surprise location kept in contact with me that same day I put the order in and was able to take my order to the Surprise location as he had been to the warehouse and said he could take it with him, In the end, it all worked out. Thank you Dan for helping me out, very much appreciated!

FAQ
Our expert staff answers customer's most asked questions.
How frequently should I clean my filter cartridges?
The cleaning frequency is contingent on your filter's size. As a general guideline, initiate the cleaning process when the filter pressure exceeds the initial pressure by 10 psi. This ensures optimal filtration efficiency.
What are the ideal chemical ranges for my pool?
Achieving a balanced pool involves maintaining a pH range of 7.2–7.8, total alkalinity between 80–120 ppm, calcium hardness at 180–220 ppm, and cyanuric acid (stabilizer) within 30–50 ppm. Chlorine levels should consistently fall within the 1–3 ppm range, by may need to be increased as CYA levels go above 60 PPM.
What is the recommended duration for running my pool equipment?
There isn't a specific timeframe, but it's essential to complete a full water turnover within a 24-hour period. Utilizing pool equipment during off-peak hours can be cost-effective.
