HTH Super Algae Guard Buying Guide: Choosing the Right Strength for Your Pool Size

Algae might be microscopic, but it’s one of the biggest headaches for pool owners. Whether you're maintaining a backyard oasis or managing a commercial pool, algae blooms can turn crystal-clear water into a murky mess, fast. That’s where HTH Super Algae Guard comes in. It’s a trusted solution designed to prevent and eliminate algae growth before it takes over. But not all pools are created equal, and neither are their chemical needs.

This guide will walk you through how to choose the right strength and dosage of HTH Super Algae Guard based on your pool’s size, usage, and environmental conditions, so you can keep your water clean, safe, and swim-ready all season long.

What Is HTH Super Algae Guard?

HTH Super Algae Guard is a non-foaming, fast-acting algaecide formulated to kill and prevent green, black, and mustard algae. It’s part of HTH’s professional-grade pool care line and is known for its effectiveness without clouding water or interfering with other treatments like chlorine or shock.

Key Features:

• Non-foaming formula: Ideal for pools with water features or jets

  
  

• Compatible with chlorine systems

• Effective against multiple algae types

• Prevents future growth with regular use

Step 1: Know Your Pool Volume

Before you even open the bottle, you need to know how many gallons your pool holds. Dosage recommendations are based on water volume, and using too little or too much can reduce effectiveness or waste product.

Common Pool Sizes:

Use a pool volume calculator or this formula for rectangular pools: Length × Width × Average Depth × 7.5 = Total Gallons

Step 2: Match Dosage to Pool Size

HTH Super Algae Guard typically comes in 1-quart or 1-gallon containers. The standard dosage for prevention is around 1.5 oz per 10,000 gallons, but for active algae treatment, you may need 3–4 oz per 10,000 gallons, depending on severity.

Dosage Chart:

Always read the label for exact instructions, as formulations may vary slightly.

Step 3: Consider Environmental Factors

Your pool’s location and usage can affect how much algaecide you need. Here’s what to factor in:

Sun Exposure

UV rays can degrade chlorine faster, reducing its ability to fight algae. Pools in full sun may need more frequent dosing.

Rain and Debris

Rain introduces organic material and dilutes chemicals. After heavy storms, a maintenance dose of HTH Super Algae Guard can help rebalance your pool.

Usage Frequency

More swimmers = more contaminants. High-traffic pools benefit from regular preventive dosing to stay ahead of algae growth.

Surrounding Landscape

Pools near trees or gardens are more prone to organic debris and spores. Consider a slightly higher preventive dose if your pool is surrounded by vegetation.

Step 4: Application Tips for Maximum Effectiveness

Applying HTH Super Algae Guard correctly ensures optimal results. Here’s how to do it right:

1. Test and balance your water: Ensure pH is between 7.2–7.6 and chlorine levels are within range.

2. Brush the pool walls and floor: Loosen any algae clinging to surfaces.

3. Add algaecide directly to the water: Pour slowly around the perimeter while the pump is running.

4. Circulate for 24 hours: Keep the filter running to distribute the product evenly.

5. Avoid swimming for 15–30 minutes: Let the product settle before use.

Step 5: Maintenance Schedule

Consistency is key. Even if your pool looks clean, algae spores are always present. A weekly maintenance dose keeps them from taking hold.

Suggested Schedule:

• Weekly preventive dose during swim season

• Post-storm dose after heavy rain or wind

• Monthly deep clean with shock + algaecide combo

• Pre-winter dose before closing the pool

Step 6: Choosing the Right Product Size

HTH Super Algae Guard is available in various sizes. Choose based on your pool volume and how often you plan to treat.

Buying Tips:

• 1-quart bottle: Ideal for small pools or occasional use

• 1-gallon jug: Best for large pools or regular maintenance

• Multi-pack bundles: Great for seasonal stocking or commercial use

Look for bulk discounts online or at local pool supply stores. Some retailers offer subscription services for automatic restocking.

Bonus: What to Avoid

Not all algaecides are created equal. Here’s what to watch out for:

• Foaming formulas: Can interfere with jets and water features

• Copper-based products: May stain surfaces or affect water clarity

• Overdosing: Can lead to chemical imbalance and skin irritation

HTH’s non-foaming, copper-free formula makes it a safer choice for most pool types.

Final Thoughts

HTH Super Algae Guard is more than just a chemical; it’s a proactive tool in your pool care arsenal. By choosing the right strength and applying it strategically, you can prevent algae before it becomes a problem. Whether you’re a homeowner or a pool maintenance pro, understanding your pool’s needs and environment will help you get the most out of every bottle.
