Episode Details

A pool doesn’t turn cloudy for no reason, and it rarely gets fixed by “just add more chlorine.” When water looks dull, hazy, or starts showing algae, we use a simple three-step reset that gets results fast because it treats the whole pool system: filtration, sanitation, and circulation.

We start where most people don’t: the filter. A dirty sand filter, DE filter, or cartridge filter can choke off flow, kill circulation, and trap the very debris you’re trying to remove. We talk about knowing your clean starting PSI, what high pressure is really telling you, and the real-world signs you’ll see at the skimmer or spillway when water isn’t moving. If you skip this step, you can shock all day and still watch the pool stay cloudy.

Then we get specific about shocking to the right level and why “err on the side of more” often makes sense when algae, combined chlorine, or heavy organic load is present. For saltwater pools, we cover when to hit boost or superchlorinate, when to dial output to 100%, and how a dirty or failing salt cell can quietly be the reason chlorine dropped to zero. Finally, we dig into the underrated move that ties everything together: running the pump 24 hours (sometimes 48), how to do it with an Intermatic timer or automation, and how to explain the electricity cost versus chemical cost to customers.

If you want a practical playbook for fixing cloudy pool water, improving pool circulation, and delivering better results as a pool service pro, press play. Subscribe, share this with a pool tech who needs it, and leave a review with your go-to method for turning a pool around.

We walk through the three-step process we use to turn a cloudy, algae-prone pool back to crystal clear blue without wasting chlorine. We focus on filtration, shock-level dosing, and nonstop circulation so the water actually has a chance to recover.
• Spotting early signs of poor pool water quality like cloudiness and algae  
• Cleaning or backwashing first so flow and circulation recover  
• Using filter PSI and visual flow clues to diagnose restriction  
• Sand, DE, and cartridge filter actions that “move the needle”  
• Shocking to the right free chlorine level based on severity  
• Setting expectations with customers about no-swim windows  
• Using salt system boost and turning output to 100%  
• Troubleshooting why chlorine hits zero and preventing repeats  
• Running the pump 24 to 48 hours using timers or automation  
• Explaining electricity cost versus chemical cost to customers
