Green Pool Treatment & Algae Removal

We Turn Green Pools Blue Again

A green pool can feel overwhelming. Maybe you went on vacation and came back to a swamp. Maybe the previous owner let it go. Or maybe the algae just took over faster than you expected. Whatever happened, you are not alone. Green pools are one of the most common problems we solve for Milpitas homeowners, and we have the experience to fix yours quickly.

Algae thrives in warm weather, and here in Milpitas, our climate creates perfect conditions for rapid growth. When algae takes hold, it turns your water murky green, makes surfaces slippery, and creates an unsafe swimming environment. The good news is that with the right treatment approach, we can restore your pool to safe, clear, beautiful water.

Our green pool treatment process is thorough and effective. We do not just shock the pool and hope for the best. We use a proven system that eliminates algae completely and prevents it from coming back.

How We Eliminate Algae Completely

Treating a green pool takes more than adding chemicals. It requires a systematic approach to kill the algae, remove it from your pool, and restore proper water balance. Here is our proven process:

• Initial assessment to determine algae type and severity
• Brushing all surfaces to break up algae colonies
• Shocking the pool with concentrated chlorine treatment
• Adding algaecide to kill remaining spores
• Running your filter continuously to remove dead algae
• Vacuuming debris and sediment from the pool floor
• Testing and rebalancing water chemistry
• Follow-up treatment if needed for stubborn cases

The timeline depends on how severe your algae problem is. Light green pools often clear in 24 to 48 hours. Dark green or black pools might take 3 to 5 days of treatment and filtering. We stay with you through the entire process.

Why You Should Not Wait

Some homeowners try to ignore a green pool or attempt DIY fixes that do not work. The longer you wait, the worse the problem becomes. Algae spreads quickly, and what starts as a light green tint can become a thick, soupy mess within days.

Beyond looking terrible, algae creates real safety concerns. It makes pool surfaces dangerously slippery, harbors bacteria that can cause illness, and provides a breeding ground for mosquitoes. Your pool also continues to deteriorate while filled with algae-laden water, potentially damaging your filter and other equipment.

Professional treatment costs less than you think, especially compared to the expense of replacing damaged equipment or dealing with ongoing algae battles. We get it right the first time, saving you money and frustration.

After we clear your algae, we recommend signing up for our weekly pool cleaning service to prevent it from returning. Regular maintenance is the best defense against future algae growth.

The Different Types of Algae We Treat

Not all algae is the same, and the treatment approach varies depending on what type has invaded your pool. We handle all varieties:

Green Algae

This is the most common type. It floats in the water, clings to walls, and gives your pool a cloudy green appearance. Green algae responds well to treatment and usually clears within a couple of days.

Mustard (Yellow) Algae

Less common but more resistant to chlorine. It appears as yellowish or sandy patches, often in shaded areas. This type requires specialized treatment and higher chemical concentrations.

Black Algae

The most stubborn variety. Black algae forms dark spots with protective layers that make it hard to kill. It requires aggressive brushing, strong chemicals, and sometimes multiple treatments. We have the tools and experience to eliminate it.

If your pool has severe staining from algae, you might also need our tile cleaning and calcium removal service after treatment. For equipment issues that contributed to algae growth, check out our equipment repair service.
