Pool Stain Removal Case Study – How Provident Pools Restored This Sacramento Pool to Perfection

When you’re enjoying your backyard pool, the last thing you want to see are unsightly stains on the walls, floor, or waterline. They can make a perfectly safe pool look dirty, and if left untreated, stains can become harder to remove over time.

Recently, a Sacramento homeowner called Provident Pools with a pool that had brown and green discoloration along the steps and deep end. They had tried brushing, shocking, and even store-bought stain removers—but nothing worked.

This is exactly the kind of challenge our team loves.

Step 1: On-Site Inspection & Stain Identification

When we arrived, we could see the pool had multiple types of stains:

• Reddish-brown spots on the plaster (likely metal-based from iron)

• Dark green patches on shaded steps (likely organic material from leaves and algae)

We used our professional stain testing kit to confirm both metal and organic staining were present. This was crucial—because using a one-size-fits-all chemical could have made one type of stain worse while only partially removing the other.

Step 2: Customized Stain Removal Plan

After identifying the stains, we built a plan:

1. Water chemistry adjustment – Balanced pH, alkalinity, and calcium hardness to optimal stain-removal levels.

2. Metal stain treatment – Applied a chelating agent to pull metals out of the surface and hold them in the water for safe filtration.

3. Organic stain removal – Used an enzymatic cleaner to break down organic residue without damaging the plaster.

4. Deep brushing & filtration – Thorough brushing loosened remaining stains, and the filtration system ran for 48 hours to remove contaminants.

Step 3: The Results – Before & After

Before: The plaster surface was blotchy with noticeable brown, green, and gray stains that stood out even from a distance.

After: Within just a few days, the pool surface looked bright, smooth, and uniform—with the blue water reflecting like a freshly finished pool.

The homeowner told us:

"We thought we’d have to re-plaster the pool. Provident Pools made it look brand new without the huge expense."
