Natural Chemistry Pool and Spa Water Care

About Natural Chemistry Pool and Spa Water Care

Founded in 1989, Natural Chemistry shifted the paradigm of pool care by asking a simple question: "Is there a better, more natural way?" While the rest of the industry relied heavily on harsh industrial chemicals, Natural Chemistry pioneered the use of powerful, naturally based enzymes—similar to those found in your own body—to break down organic waste.

What started as a single enzyme formula to combat scum lines has grown into North America’s leading authority on specialty pool water care. Their philosophy is built on "biomimicry"—using technologies inspired by nature to solve common pool problems like algae fuel (phosphates) and greasy buildup. By breaking down contaminants rather than just masking them, their products often reduce the need for excessive sanitizers and scrubbing. For the DIY homeowner, Natural Chemistry represents the "work smarter, not harder" approach to maintenance, delivering high-end results with eco-conscious science.

Why We Trust Natural Chemistry Pool and Spa Water Care
Pioneering Enzyme Technology: They were the first to successfully stabilize natural enzymes for pool use, allowing water to "digest" oils, lotions, and pollen naturally.

Problem-Solving Focus: Rather than generic fixes, they manufacture targeted solutions for specific headaches, such as high phosphates (Phosfree) or persistent scum lines.

Efficiency & Simplicity: Their core promise is to reduce maintenance time and effort, polishing water so it sparkles without constant manual labor.

Eco-Conscious Chemistry: By removing organic load efficiently, their products often help sanitizers work more effectively, potentially lowering the total chemical burden in the pool.

How to Choose the Right Strength
Not all phosphate removers are created equal. The right choice depends entirely on your current phosphate level (ppb). You must test your water before buying.

Level 1: The "Red Alert" (Levels > 1,000 ppb)

  • What you need: High-Concentrate / Commercial Strength Remover.
  • Why: You have a massive surplus of algae food. Using a standard bottle here is like using a garden hose on a forest fire. You need a potent dose of Lanthanum to drop levels quickly.
  • Expectation: Your water will turn milky white, and your filter pressure will spike. This is normal.

Level 2: The "Correction" (Levels 300 – 1,000 ppb)

  • What you need: Standard Strength Remover.
  • Why: Your levels are creeping up, likely due to heavy rain or fertilizer drift. A standard dose will drop you back into the safe zone without overwhelming your filter instantly.

Level 3: The "Insurance Policy" (Levels < 300 ppb)

  • What you need: Maintenance Remover or "Phos+Enzyme" Blend.
  • Why: You are in the safe zone. These lower-concentration products (often capped at removing 100–200 ppb per week) are designed to "skim" new phosphates off the top before they accumulate, often keeping water clearer than high-strength alternatives.

Algae’s "Starvation Diet": How Phosphate Removers Work
Think of phosphates as an "all-you-can-eat buffet" for algae. Derived from fertilizer drift, decaying leaves, and bather waste, phosphates accumulate in your water, acting as a high-potency fertilizer that allows algae to survive even in chlorinated water.

Phosphate removers act as the ultimate diet plan. These formulas typically utilize Lanthanum, a rare-earth element that acts as a phosphate magnet. When introduced to the water, the Lanthanum seeks out and bonds with dissolved orthophosphates. This reaction is instantaneous and creates a visible result: the two chemicals fuse into a solid white particle (precipitate).

This process often turns the water temporarily cloudy—this is a good sign! That cloudiness is the physical manifestation of phosphates being pulled out of solution. Once solid, these particles are large enough to be trapped by your filter. By running your filtration system, you physically move the algae food from the pool into the filter, where it can be backwashed or rinsed away, leaving your sanitizer to work efficiently without interference.

Common Questions +

Why did my pool turn cloudy immediately after use?
This is normal and indicates the product is working. The remover reacts with dissolved phosphates to form insoluble white solids (precipitate). The higher your phosphate levels, the cloudier the water will become. This haze will clear as your filter catches the particles.

Does this product kill algae?
No. Phosphate removers are a preventative measure, not an algaecide. They remove the food source (nutrient starvation) to prevent future growth. If you currently have green water, treat the algae with shock and algaecide first, then use a phosphate remover once the algae is dead.

When is it safe to swim?
The product itself is non-toxic, but you should not swim while the water is cloudy. Cloudiness acts as a visibility hazard, preventing you from seeing the bottom of the pool or a swimmer in distress. You may swim once the water is clear.

Why is my filter pressure rising so fast?
The product turns dissolved gasses/liquids into solids. Your filter is rapidly "catching" all this new debris. It is standard protocol to watch your pressure gauge and backwash or clean your filter cartridges 24–48 hours after treatment to permanently remove the phosphates from the system.

How do I know if I need this?
You cannot see phosphates with the naked eye. We recommend using a digital test kit or strip to measure your levels. Ideal ranges are below 200 ppb (parts per billion). Treatment is usually required if levels exceed 500 ppb.
