Normally, swimming pools should be crystal clear and set for a rejuvenating swim at whatever time of the day or night. However, stagnant water tends to grow algae and bacteria over time, an action that changes the color of your water.
A green swimming pool implies that it is dirty and not suitable to swim in. The number of efforts needed to clean it depends on how long the backlog has progressed as well as whether you know how to clean a green swimming pool . To bring you to speed, here are reasons why your pool water can turn green
- Incorrect pH Balance
Normally, chlorine is added to pool water to destroy bacteria that accumulate with time and cause water discoloration. Green water usually indicates the presence of algae and not necessarily bacteria. However, different bacteria can affect different pools. If your pool does not have a balanced pH level, bacteria will thrive, causing more discoloration.
Very low pH levels indicate acidic water and with time, plastic and metal parts will get corroded. A higher pH level does not destroy bacteria and it promotes the accumulation of calcium among other minerals. A range of 7.2 to 7.8 on the pH scale is recommended for a healthy pool.
- Blocked Filter
It is not always that discoloration will be caused by water itself. For instance, a dysfunctional filter system cannot remove the surface algae and other waste. If allowed to stagnate, your swimming pool becomes a habitat for algae, mold, and fungi that alters the color of the water.
Pool filters are made to be cleansed with baskets, buckets, and systems that can be dismantled easily. Clean the filter to clear the blockage that causes discoloration of water.
For most pools, the filters can be removed, cleaned, and replaced. For this purpose, follow the manufacturer’s instructions to the latter.
Algae flourish in warm, damp temperatures. Although normal chlorine cannot effectively counter the growth of algae, you can get special algaecides made to work on the tough algae in the warm seasons.
If the pH level is correct but the water still goes green, algae are the cause and it requires an extra application of algae remover.
- Shock Treatment
This is a temporary solution applied when there are extreme algae and other waste buildups which are causing water discoloration even when the pH level is in check. The only way to solve this is by shocking the pool. This entails treating it with an overdose of chlorine and algaecide and allowing it to rest for 24 hours.
- Regular Maintenance
Maintaining your pool regularly is the best solution for a green pool. This entails vacuuming the pool bottom constantly, scrubbing and vacuuming the walls, skimming the surface to get rid of waste, frequently cleansing the filter system, monitoring the pH levels, and adding more chlorine and algaecides.
Pool maintenance is an all-rounded task that needs daily focus. You can seek help from a swimming pool services company for the best results.
