Why Use Muriatic Acid for Cleaning Pool Filters?
Muriatic acid is diluted hydrochloric acid. It’s a powerful cleaning agent commonly used to lower pH levels in pools, and it works wonders for filter cleaning. When your filter cartridge is clogged with calcium buildup, algae, or debris, cleaning pool filter with muriatic acid helps dissolve those stubborn particles, restoring water flow and improving filtration.
Signs It’s Time to Use Muriatic Acid for Cleaning Pool Filters
If your pool water looks dull or the pressure gauge on the filter shows high PSI, it’s a good sign that your filters need a deep cleaning. Regular rinsing can only do so much—sometimes the problem runs deeper. Here are a few signs that you might need to use muriatic acid:
- Pool pump pressure stays high even after rinsing the filters.
- Water flow through the filter seems weak or uneven.
- Algae buildup is clogging the pool filter cartridges.
- Mineral deposits are visible on the filter housing or filter cartridge.
How to Clean Pool Filter with Muriatic Acid: A Simple Guide
Cleaning cartridge pool filter with muriatic acid may seem tricky at first, but if you follow these steps, it’s easy to do and safe for your pool.
Step 1: Turn Off the Pool System
Before starting, turn off the pool pump and release any pressure in the system. Open the filter housing and take out the filter cartridge.
Step 2: Rinse Off the Filter
Use the garden hose to wash away loose dirt, leaves, or any debris stuck in the filters. This makes the acid soak more effective.
Step 3: Prepare the Acid Solution
In a plastic bucket, mix one part of muriatic acid with ten parts water. Always add acid to water, never water to acid—it’s safer that way.
Safety Tip: Wear gloves, goggles, and protective clothing to avoid skin irritation. Work in a well-ventilated area to avoid inhaling fumes.
Step 4: Soak the Filter
Wondering how long to soak pool filters in muriatic acid? Soak the filter cartridge for 1 to 2 hours. This will break down any minerals, dirt, or algae clinging to the filter.
Step 5: Rinse Thoroughly
After soaking, rinse the filters thoroughly to remove all traces of acid. Skipping this step can allow acid to enter the pool system, which can damage parts like the pool pump.
How Much Muriatic Acid to Clean Pool Filters?
You don’t need much muriatic acid for cleaning pool filters—about 1 gallon mixed with 10 gallons of water will be enough for most cartridge filters. If you’re working with larger filters, you can double the amount, but always stick to the 1:10 ratio to stay safe.
Can Muriatic Acid Remove Algae from Filters?
Yes! If you’re struggling with algae, muriatic acid is a great solution. Cleaning pool filters with muriatic acid kills algae spores and clears up clogs caused by algae buildup. Make sure to rinse the filter cartridge thoroughly after the acid soak to avoid introducing acid into the pool water.
