Pool Shock Advice & Tips

June 24, 2020

We keep and compile all of the best pool shock advice from our experts and around the web so you can get the answer you need quickly.  

When it comes to pool shock, less is more.  First and foremost, all pools are different but generally if you keep your water chemistry in balance and your water looks clear, there is no need to shock your pool on a regular basis.

Shocking with an automatic chlorinator

If it rains, a lot of kids have been in the pool all day, or there's a string of sunny days, the normally balanced chlorine feed won't be able to keep up, and you may need to shock to pump the levels back to where the chlorinator can manage it again. This means pretty much once every week or two you'll need to do a maintenance shock. All pools are different, but that's a pretty common experience.

15,000 Gallon Pool Shocking

Non-chlorine shock is to allow you to use less chlorine shock. It helps keep the water balanced and increase the strength of the chlorine without having to actually raise the levels. We would recommend keeping up with the non-chlorine shock during pool season and use the chlorinated shock as needed. For a 15,000 gallon-sized pool though, shouldn't be a need to use more than 2 lbs of either.

An Alternative to Pool Shock - Liquid Chlorine

We've maintained a 15,000 gallon saltwater pool for three years running and have never "shocked" it. There are times after a lot of people are in the pool or a power outage has knocked out the salt cell generator that makes the chlorine that a quick test will reveal 0 chlorine in the pool. When that happens, you can use a liquid chlorine to raise the levels back to a normal range.

Sometimes at the start of the season, when the water temp is less than 60 degrees, you can use liquid chlorine for a few days until the chlorine generator has a chance to catch-up.

Test, Test, Test again.

Again the most important thing is to monitor your pool chemistry to hopefully avoid having to shock the pool at all.
