How to Clean a Green Swimming Pool Fast

Step by Step

Step
1

Skim

Using your skimmer net, remove as much large floating debris and “algae patties” from the pool as possible.

Step
2

Vacuum

Set your system to “vacuum to waste” and using your pool vacuum remove as much large debris and sludge from the bottom of the pool as possible.

Step
3

Add Swamp Treat™

Add one (1) bottle of Swamp Treat™ per 20,000 gallons of pool water.

Step
4

Brush

Brush the walls of the pool. A quick brush over the wall should be sufficient.

Step
5

Shock

Add approximately 2 pounds/gallons of chlorine pool shock per 10,000 gallons – cascading it around the pool.

Step
6

Run the Filter

Set your system back to filter, and turn the pump on. Allow to filter for 24 hours. Continue to filter and backwash as necessary until the pool clears up.

What is Green Algae?

Green algae is the most common form of swimming pool algae, typically appearing as a slimy green film on your pool’s walls, steps, and floor, or as a cloudy green tint suspended in the water. It is a microscopic plant-like organism that thrives in warm water, sunlight, and the presence of nitrates or phosphates—often taking hold when sanitizer levels drop, or circulation is poor. While unsightly, it is a very manageable issue. It essentially feeds on the organic debris in your water, turning your pool into a “swamp,” but with the proper chemical treatment and physical removal, it can be eradicated quickly.
