⚙️ Why Removing Metals from Your Pool or Spa Matters
Metals like iron, copper, and manganese are often invisible when you first fill your pool or spa — but they’re almost always present. These metals can come from source water (especially wells), aging plumbing, or chemical additives.
If left untreated, metals can:
-
⚠️ Cause permanent staining on spa surfaces and vinyl liners
-
💧 Discolor the water, making it appear green, brown, or cloudy
-
🔧 Damage equipment over time through corrosion or buildup
🧪 The Role of Oxidation & How to Prevent It
Once you add sanitizer (like chlorine or bromine), it triggers oxidation — a chemical process that causes metals to fall out of solution. This leads to metal staining and water discoloration.
To prevent oxidation stains, it's important to remove or neutralize metals before adding any sanitizer.
✔️ How to Remove Metals from Your Pool or Spa Water
1. 🌀 Use a Hose-End Pre-Filter
Before filling your spa or pool, we recommend attaching a Pleatco PureStart Pre-Filter to your garden hose.
These filters trap sediment and heavy metals before they ever enter your water.
2. 💧 Add a Metal Sequestrant
We highly recommend Unique Metal Remover, a professional-grade chemical that binds with metals in your water and keeps them in solution, making them easier to filter out.
Pro tip: Always add your metal remover before you introduce sanitizer to avoid oxidation staining.
🛠️ Ongoing Maintenance Tips
-
🧪 Test your water regularly – especially if you use well water or notice staining
-
🧼 Clean or replace filters routinely for maximum efficiency
-
⚖️ Keep water balanced to prevent corrosion and further metal release
