It hot!
High temperatures like we’ve had this spring and summer can lead to perplexing and even dangerous problems.
Algae
Algae love water that’s in the 90’s. Stay on top of your free chlorine (or bromine) levels and use a good algaecide like SeaKlear 90 Day Algae Prevention and Removal to prevent or treat an algae bloom. When it’s this hot out and there are many swimmers, there’s no margin for error, so check your chemical levels daily. In a busy public pool, check those levels throughout the day.

Pathogens
Human pathogens such as cryptosporidium thrive in warm, untreated water. In addition to chlorine, consider the use of SeaKlear PRS to prevent chlorine resistant crypto. Learn more at http://www.hinespool.com/pages/crypto.html.
Evaporation
Your pool will lose 1/4” to 1/2” of water daily in this hot weather. Don’t let the water level go below the bottom of your skimmer throat. If you do, equipment damage may occur. If you are losing more water than 1/2” an inch per day, you may have a leak. To learn how to test for the difference between normal water loss and a leak, go to http://www.hinespool.com/leak_detection.htm.
Ground Movement
In a period of extended drought, the ground shrinks. This can cause plumbing to crack and the pool shell or deck to become unsupported and shift. Be sure to water around the perimeter of the deck to keep the ground around your pool stable.
Motors
Motors heat up during normal use. When it’s 105 degrees out, it is especially important to keep the vents at the front of the motor clear to allow air to circulate.
Fountains
A great way to keep cool your water is to use a fountain at night when the air is cooler. Polaris sells a fountain that connects to the Polaris booster port or a a threaded return line. If you have a large public pool, Hines can build an aeration device that will cool your water at night. Call us for more information.
