There are several key reasons why chlorine consumption increases dramatically during the summer months. Unlike in the colder months when a pool has infrequent or no use, once Summer arrives and the air temperature starts to rise, a pool’s water temperature increases and therefore, pool usage begins to go up dramatically. The job of chlorine is to destroy all the bad things in the water - organic debris, skin cells, bodily fluids, and algae. Due to increased usage, there are more bad things in the water, and in warmer water temperatures, algae thrives. To keep the pool water properly sanitized, chlorine levels must be increased. Another item that necessitates more chlorine is the addition of fresh water to the pool due to evaporation and more frequent backwashing. Water loss between ¼” and ½” each day is expected. If water loss is greater than ½” per day, there may be other issues contributing to the loss. Give us a call and we can investigate this abnormal water loss with our leak detection services.
On a related topic - circulation, most pools should be circulating between 14-18hrs per day (more in some cases) during the summer months and twice weekly brushing of the pool walls and floor is recommended. If algae is present, circulate the pool 24hrs per day and brush daily until the algae is gone.
Sunblock and the Effects on Your Pool
Have you ever noticed when a person jumps in the pool and an oil slick trails behind them? That person likely just applied sunblock and jumped in the water before allowing the sunblock to soak in. It takes roughly 15-20 minutes for sunblock to soak into the skin to provide adequate protection. This is true even for water resistant blocks. Water resistant blocks are resistant once they soak in, not immediately after application. If sunblock is not allowed to soak in, the lotion will wash off into the water causing a couple issues. First, the oil in the sunblock will create a scumline on your tile. Not only is the oil attaching to the tile, but now it becomes as effective as a spider web in capturing prey, grabbing everything floating on the surface. Keeping your tile clean can become difficult if you don’t stay ahead of the issue.
Sunblock and oils can also clog your filter making it less effective. Over time, oils begin to coat the sand in a sand filter, grids in a DE filter, and cartridges in a cartridge filter causing higher filter pressure and require more frequent back-washing or cleaning of your cartridges. Without treatment, DE grids or filter cartridges can be damaged and sand changes may be required more frequently. Keep an eye on your pressure gauge and backwash/clean whenever the pressure is 8-10 PSI above clean pressure.
To prevent the buildup of oils in pool water use Bio-Dex Oil-Out to remove and eliminate oils as well as help keep the filter media oil free. If a problem already exists, we have several other products which can help:
Use Bio-Dex Quick ‘n Thick if a scumline is present
Use Bio-Dex 300 Tile Cleaner if calcium is built up in addition to a scumline
