Why Is My Pool Green?
There are several reasons why a swimming pool may turn green, but most of these issues can be traced to improper pH/alkaline levels. Other causes include algae growth, metal presence, a failing filtration system or organic debris found in the water.
An issue like improper pH or alkaline levels is something that requires a testing kit. Measure the levels with the testing kit, then adjust accordingly using chlorine or algaecide.
Cleaning A Green Pool
If you are attempting to fix a green pool yourself, it’s important to follow a few steps for this procedure. The truth is the pool professionals follow these same steps, as well. Severe green pool situations will call for a complete draining of the pool and a power spray until the tiles are clean.
Step 1. Remove Any Organic Debris
The first step is to find and remove any debris from the pool area. Debris can include insects, leaves, tree branches and anything else that has fallen into the water and can circulate bacteria. By removing debris first, it will make things easier on the filtration system. This will guarantee that any added pool chemicals will not be hindered by debris during the cleaning process.
This will also provide the added benefit of preventing or at least decreasing the growth of algae spores in the water. Try not to disrupt the water too much, though, as this can cause bacteria to circulate further.
Step 2. Assess Pool Water Chemistry
You will need to utilize a pool testing kit to determine your pool chemistry, including pH, chlorine, bromine, acid demand and alkalinity levels. When needed, you can take a sample of your pool water and bring it to a local pool store for testing. The experts say you will need to take a water sample 12-18 inches below the surface. Make sure to take a sample in the morning before the sun has a chance to burn off chlorine.
Step 3. Shock Pool Water
Shocking pool water essentially means you will be increasing the chlorine levels above the recommended levels. This will help to kill any bacteria, in addition to any algae that may be leftover after organic debris has been removed.
Typically, shocking the water can turn it cloudy, but it should clear up within 48 hours. It is recommended to shock a pool at nighttime in order to bypass UV interference. Ensure pH levels are between 7.2-7.4 for ideal results.
Step 4. Pool Filter/Vacuum
It’s now time to filter and vacuum your pool area. By vacuuming the pool before running the filter, you are making the job easier on the cartridge sand or Diatomaceous Earth filter (DE). When this step is not performed properly, you may need to call a professional to replace your pool pump. Run the filter for at least 24 hours straight and backwash the filters to prevent clogs from entering the filtration system.
Step 5. Perform Routine Maintenance
After the green, cloudy water is gone, it’s time focus on daily, weekly, monthly and yearly upkeep of your pool. Ensure you backwash your filters regularly, in addition to skimming any debris from the water often.
