Why Pools Turn Green and What It Means

Green water means algae has taken over your pool. This happens when chlorine levels drop too low or when the pool goes without proper circulation and filtration. Algae loves warm, stagnant water, and once it starts growing, it spreads fast.

Here in Oxnard, CA, our year-round warm weather creates perfect conditions for algae growth. A pool can turn from clear to green in just a few days if maintenance gets skipped. Maybe your pump broke, you went on vacation, or life just got busy. Whatever the reason, algae does not care. It moves in quickly.

The good news is that green pools can be saved. You do not need to drain it or start over. Our specialized treatment process kills the algae, clears the water, and restores proper balance. After we are done, your pool will look like nothing ever happened. Many homeowners find us through emergency pool recovery services when their pool has gotten out of control.

Our Green Pool Recovery Process

Clearing a green pool takes more than just adding chlorine and hoping for the best. We follow a proven process that works every time:

  • Remove all large debris like leaves, branches, and trash
  • Test water chemistry to determine treatment strength needed
  • Brush all walls and floor to break up algae colonies
  • Add algaecide to kill algae at its roots
  • Shock the pool with high doses of chlorine to oxidize dead algae
  • Run the filter continuously to remove dead algae particles
  • Vacuum sediment from the pool floor once water clears
  • Balance all chemicals for safe, comfortable swimming

The whole process takes 3 to 7 days depending on how bad the algae problem is. Light green water might clear in 3 days. Dark green or black water takes longer. We come back for follow-up visits to keep the treatment on track and make sure the algae does not come back.

What to Expect During Treatment

During the first visit, we assess the damage and start the treatment. The water will look worse before it looks better. As algae dies, it turns the water cloudy or milky white. That is normal and means the chemicals are working.

Your filter will work overtime during treatment. We check it frequently and clean or backwash as needed. A clogged filter slows everything down, so keeping it clean is critical. If your filter is old or damaged, we might recommend filter replacement to speed up recovery.

After 3 to 5 days, the water starts clearing. You will see the bottom of the pool again. That is when we vacuum out all the dead algae that has settled. Then we fine-tune the chemistry and run a final test. When everything checks out, your pool is ready to enjoy again. If you want to prevent this from happening again, our weekly maintenance service keeps algae from ever taking hold.

Preventing Future Algae Problems

Once your pool is clear, you want to keep it that way. Algae prevention is simple if you stay consistent. The most important factor is maintaining proper chlorine levels. Chlorine kills algae before it can grow. When chlorine drops too low, algae moves in within days.

Your filter also plays a huge role. A clean, working filter removes algae spores before they multiply. Run your pump at least 8 hours per day during warm months. Check your filter pressure regularly and clean it when pressure gets high.

Regular brushing helps too. Algae clings to walls, steps, and corners. Brushing once per week keeps it from getting a foothold. If you do not have time for weekly maintenance, we handle all of this for you so you never see green water again.
