(Frequently Asked Questions)
Q: How do I calculate the volume of water (in gallons) that my pool contains?
A: You must measure Length, Width, & Avg Depth. For circular pools and spas, you need to measure the radius (R). A handy online calculator is available for simplicity at Pentairpool.com (Opens in new window) Otherwise, the formulas depend on the general shape of your pool as follows:
Rectangular is L x W x Avg Depth x 7.5 = Volume in Gallons.
Circular is R^2 x3.14 x Avg Depth x 7.5 = Volume in Gallons.
Q: When should I run my pool filter and for how long?
A: Usually the best time to run the pool filter is during the day. The length of time is different for each pool depending on the volume of water in your pool and the pump motor speed. Your pool should "turn-over" once per day. This gets all the pool water through the filter every day. Consult with our pool technicians to help determine your pool's turnover rate.
Q: What is "Conditioner" and why is it needed?
A: Conditioner is the common name for cyanuric acid. This is a stabilizer for your chlorine level. Chlorine is very sensitive to the sun's ultra violet rays and will "burn off" within a few hours if not treated. With the proper amount of cyanuric acid (NOT MURIATIC ACID), your chlorine can be up to 80% more effecient.
Q: If my water looks clean, why does my pool need to be drained and refilled?
A: All pools will need to be drained and refilled approximately every 3-5 years when the Total Dissolved Solids (TDS) are measuring over 2,500. This is primarily due to evaporation. Pool water evaporates at a rate of approximately 1 inch per week (more in the summer). When evaporation occurs, only the pure water molecules leave the pool. All pool water has minerals, calcium, and other hard water deposits that stay in the pool and get concentrated over time. These solids can not be removed chemically. The only way to reduce the TDS to normal levels (between 1,000 - 2,000) is to drain and refill the pool. Ashworth Pool Care technicians test your TDS levels quarterly and will let you know when a draining (or partial drain) is needed.
Q: If I have a weekly pool service like yours, do I need an automatic vacuum?
A: No you don't need an automatic pool vacuum, but we do recommend it. Not only is it a time-saver for us, but it also helps keep your pool clean in-between our weekly visits. We have several brands we recommend depending on your pool shape and size. We have access to great discounts that we pass on to you and can even install it for you.
