Why Algae Love Simi Valley Summers

Prevent pool algae: Algae are microscopic organisms that thrive in warm, sunny water—just like the kind Simi Valley experiences from late spring to early fall. Add in any lapse in water chemistry, poor circulation, or a clogged filter, and algae can bloom overnight. 

Key Conditions That Encourage Pool Algae:

  • High temperatures

  • Direct sunlight

  • Low chlorine levels

  • Poor circulation

  • Phosphate-rich water

  • Organic contaminants (leaves, body oils, etc.)

Top Strategies to Prevent Pool Algae Growth

1. Maintain Proper Chlorine Levels

Chlorine is your pool’s first line of defense. In hot weather, chlorine burns off faster due to UV exposure, especially if your pool doesn’t have the right level of conditioner (CYA).

Pro Tip:

to help prevent pool algae form forming, keep chlorine levels between 3–5 ppm in summer. Monitor them more often during heatwaves and after heavy usage.

2. Brush Your Pool Regularly

Pool Algae cling to surfaces like plaster, tile, and ladders. Brushing breaks up algae colonies and exposes them to chlorine.

Suggested Brushing Schedule:

  • Every 2–3 days in summer

  • Focus on corners, steps, and behind ladders

  • Use a stainless steel brush for plaster or a nylon brush for vinyl

Our weekly pool service in Simi Valley includes brushing and scrubbing trouble spots.

3. Improve Water Circulation

Dead spots in your pool areas where water doesn’t move are breeding grounds for pool algae. Common places include steps, corners, and behind skimmers.

Fixes:

  • Adjust return jets to improve flow

  • Run your pump for at least 10–12 hours per day in summer

  • Upgrade to a variable-speed pump for better efficiency and circulation

4. Remove Phosphates

Phosphates are algae food. They enter your pool through fertilizers, decaying leaves, rainwater, or tap water. High phosphate levels can make it hard to control pool algae even with good chlorine levels.

How to Manage Phosphates:

  • Use a phosphate remover monthly

  • Skim leaves and debris daily

  • Rinse off pets or people who’ve been in grassy or dusty areas

At SoCal Poolfection, we test and treat phosphate levels as part of our green-to-clean and weekly pool services.

5. Shock Your Pool After Heavy Use

A pool party or heatwave can exhaust your sanitizer levels. Shocking restores free chlorine and helps oxidize organic contaminants before algae have a chance to grow. This will help prevent pool algae from growing. 

When to Shock:

  • After a pool party

  • Following a storm

  • If water appears cloudy or smells odd

Use a non-chlorine shock weekly, or a chlorine shock when levels drop or algae is suspected.

6. Clean or Backwash Your Filter

A dirty or clogged filter means poor water clarity and low circulation—two key causes of algae.

Filter Maintenance:

  • Backwash sand or DE filters every 2–4 weeks

  • Clean cartridge filters monthly

  • Replace filter media annually if needed

Our filter cleaning service in Simi Valley helps your pool system run smoothly and algae free.

7. Test and Balance Water Weekly

Unbalanced water reduces chlorine’s effectiveness. You should be testing pH, alkalinity, CYA (conditioner), and calcium hardness regularly.

Target Levels:

  • pH: 7.4–7.6

  • Total Alkalinity: 80–120 ppm

  • CYA: 55–70 ppm

  • Calcium: 200–400 ppm

At SoCal Poolfection, we use professional-grade kits to dial in water chemistry every visit.

Algae Warning Signs to Watch For

Even when you’re doing everything right, algae can sneak in. Here’s how to spot it early:

  • Water turns dull, hazy, or greenish

  • Slimy walls or steps

  • Yellowish dust that brushes off easily

  • Black spots that don’t brush off (black algae)

The sooner you catch it, the easier it is to treat. If you’re unsure, we offer free water checks in Simi Valley.

Green-to-Clean: What to Do if Algae Takes Over

If algae has already bloomed, don’t panic. Our green-to-clean service can restore your pool within days.

Typical Steps:

  1. Kill algae with algaecide and shock

  2. Brush and vacuum the pool

  3. Backwash or clean filter

  4. Rebalance water chemistry

  5. Optional: Chlorine wash for severe cases

Real Pool Success Story – Wood Ranch, Simi Valley

A homeowner in the Wood Ranch area contacted us with a pool that turned green overnight during a 110°F heatwave. Their filter was dirty, phosphates were off the charts, and chlorine was barely traceable.

We:

  • Rebalanced the water over 3 days

Within a week, their pool was sparkling—and algae-free.
