Seasoned pool owners know shocking is important to water care. When new pool owners research maintenance tips, they quickly find the advice: “Shock your pool. Shock your pool. Shock your pool.”
But, why do we shock?
Regular pool shocks are critical to keeping the water safe, and to maintaining balanced water.
The main reason you need to shock is to get rid of the chloramines in the pool, which can be responsible for eye irritation and an ammonia smell. Shocking is an extra boost to burn off of bacteria so that the free chlorine can do its job.
Chlorine or bromine sanitizers can get overworked and need to be removed from the pool. This could be after a heavy rainstorm, lots of kids in the pool, or a pool party. Using a non-chlorine shock is the first step to eliminating bacteria, and doesn’t disrupt your chlorine or bromine levels, so your water can remain balanced.
How do you shock?
- Check the label: If you have shock for a chlorine pool, carefully read the instructions to know how long the manufacturer recommends waiting before you can swim.
- Set a schedule: Shocking your pool should be done each week – and it can be as simple as tossing a pod in the water. There are many brands that offer shock, so find what works best for your pool, or consult a local pool retailer or service technician.
- Pick a time: Shock your pool when it’s not going to be occupied. These chemicals aren’t stabilized, so you may have to stay out of the water for at least a few hours to let the shock spread and start working, depending on the type of shock you’re using. Evenings or late afternoons work, or if you’re not a morning swimmer, maybe your shock can be in the morning.
In addition to pool shocking, make sure you check your pool water balance regularly. The right water balance keeps your pool safe to jump in anytime, and it can be simple. Pool experts created the pHin Smart Monitor, a system that measures your pool water chemistry, sends you alerts, and helps with chemical dosing.
