Regardless of whether you're opening or closing your pool, this all-in-one cleaning guide will take you through the key tasks to help your pool sparkle again. However, unlike a spring clean of the house, fixing murky or green pools can take a few days.
No matter what your situation, there are 4 key tasks that need to be completed to get the health of your pool back on track. They are:
There will likely be a layer of scum on the surface of the pool. Use a leaf net (not a skimmer) to remove debris from the water surface. Leaf nets are available at hardware stores and some pool shops.
A murky pool is likely abundant in unwanted bacteria and unsafe for use. To combat this, you need to adjust the chemicals. First, you need to determine your chemical levels by using a test strip. Then, you need to use a pH reducer and increaser until you find the ideal level, which is around 7.5 and 7.8. Note, you may also need an alkalinity increaser.
If there is a large build-up of algae, you need to shock the pool. Add 12-14L of shock over the course of a few days. If administered correctly, the water will change to cloudy white, light green, or clear. If nothing has changed, continue to add more shock.
You'll need to run the pool filter 24 hours a day for a few days to clear unwanted debris and bacteria that has accumulated in the pool. Be sure to backwash your filter 3-4 times per day. Green water can clog and damage a filter, and it is normal to backwash frequently while cleaning murky pools. Note, if your pool does not clear, you should contact a pool professional to have your filtration system checked.
The final step is cleaning the pool floor. This can be done manually with a long pool brush, or with a robotic pool cleaner. However, in extreme cases of debris build-up, we recommend consulting a pool professional to ensure your pool is safe for swimming. In all cases, regularly check your pipes for clogs and filtration system for wear to avoid further damage.
