Shocked your pool and its still green?
Sadly, there’s no magic wand to wave to make your pool crystal clear overnight.
If your pool water has turned into a lovely shade of green, chemically shocking your pool is your best bet to get it back into shape.
To ensure your pool returns to normal, there are three things you’ll need to get your pool back into shape: the correct chemicals, a filtration system, and of course, plenty of patience.
After completing the entire process outlined below, you should start to see your pool crystal clear, sparkling new and ready for a splash.
If you find your pool still murky green after you do complete a shock treatment, don’t panic.
This can be easily fixed!
Step one: Prepare your pool water for testing & shocking
Some people may sit and wonder why their pool turned green in the first place.
This occurs when there is an overabundance of metal elements and little to no chlorine in the water.
To start the process you will first need to clean up any visible debris in the water by using a leaf net.
Don’t panic if it briefly looks worse while you remove most of the larger debris.
As you are stirring up the water other smaller fragments will eventually settle down once again in a few hours.
Step two: Test the water
The first test is intended to check the waters pH levels (not chlorine levels as you’re going to shock the pool anyway).
We recommend doing this as your pH level will dictate whether or not you’ll need to add anything else to help the process along.
You can use inexpensive test strips or a complete kit to do this part of the process.
The kits usually contain all the chemicals you’ll need.
Ideally, you want your pH reading to be on the lower end of the spectrum.
If you do receive a higher reading this simply means your water is alkaline and may potentially turn cloudier than normal after the shock treatment.
You simply need to introduce hydrochloric acid to the water as this acid neutralises basic elements.
Don’t worry if you’ve accidentally added too much.
Since you’ll be retesting the levels after you shock the pool, you can make any further adjustments then.
Step three: Shocking the pool
Once you have a pH reading at around 7 you can start the process of shocking the pool.
To do this you’ll need liquid chlorine.
First, disburse your chosen form of chlorine to the water evenly around the pool (until you’ve used the entire product) and turn on your filter pump.
Allow this to circulate for several hours.
At this stage, ensure you brush your pool thoroughly.
It’s also a good idea to use a quality algaecide as well which is suitable for your pool.
Step four: Pumping & filtration
Continue to run your filter normally for a few days (exact time frames can vary depending on your filter – please read below).
For the quickest results try and backwash your filter up to four times a day.
We recommend this frequently as hazy jade-green water will clog your filter quickly.
Types of filters
- If you have a Sand Filter continue with the above process however it is recommended you check your filter daily and backwash it if you see the average psi escalate to at least five above your pool’s “normal” level when it’s clear.
- If you have a Cartridge Filter you much check to ensure it’s in good working condition prior to commencing. With a cartridge filter, you’ll need to clean your pool more often in comparison to other filters available. Run the filter twice a day for at least two days, or until the pool is clear.
The end result
After twenty-four hours of chemical treatments and circulation, your pool will begin to transform.
While it shouldn’t be green anymore, don’t jump in just yet!
Prior to taking the first plunge back in repeat the earlier pH test.
If all levels are clear, backwash your filter one last time and then you’re ready to go!
