Cloudy Water in a Salt Pool

How long are you running your pool a day? When it's summer time the pool should run min. 8 hrs to make enough chlorine sometimes longer depending on use. Whats your conditioner at? When is the last time you cleaned your filter?
When your pool gets cloudy the first thing you want to do is shock the pool with liquide chlorine as a salt system can not do it. So adding enough chlorine to go 3-4 times the normal range is what you do to shock your pool. You have to run your pool 24/7 until clear checking the chlorine shock level to keep it high.
Know if you have a DE or cartridge filter sized correct you would never have to flock your pool unless you have a cheap sand filter that makes pool problems take way to long compared to the DE/cartridge.

Cloudy Water in a Salt Pool

It can be complicated deciding which pool is best for your family. Many questions revolve around salt-water pools or chlorine free pools. Salt-water pools are NOT chlorine free pools. A salt-water pool is simply one that utilizes a chlorine generator. Chlorine generators have been around for decades, and as technology and materials continue to evolve, they continue to improve in performance.

Okay I solved my cloudy water issue for my saltwater pool first I started by cleaning all the filters really well you have to have a good filter system secondly make sure you have enough salt in the pool if all your chemicals are good levels I would shock your pool again I added liquid clarifier and shocked my pool and it cleared right up if you don't have enough free chlorine in your water that is what's causing your pool to be cloudy make sure you are running your salt generator for it adequate amount of time I ran mine on boost mode for 8 hours and it cleared up

The cloudiness is caused by particles floating in the water, this is generally the result of the chlorine oxidizing anything in the water (sun tan lotions, skin cells, hair conditioners, algae, oils from your skin etc). Typically it happens after heavy use (because of contaminants in the water) or a rainfall (acidic rain changes the PH of the water allowing algae to grow).

Green or teal colored cloudiness is algae related, and after shocking the pool, the chlorine kills the algae and turns it grey.
Grey cloudiness is good, it means the chlorine killed and dissolved anything in the pool and now you're just waiting for your pool filter to remove it.
Cloudiness can also be caused by a dirty filter that can no longer clean the water.
The first step to fixing the cloudiness should be to clean your filter.
Then if you want to speed up the filtration process you can use a Floc product, I've used them but they didn't do anything. I also tried Polysheen blue which is a water clarifier, this worked much better and i could see the difference in couple hours, after a day the cloudiness was pretty much gone. The three great things about the polysheen are 1. You only use 100ml of it per treatment (1/10th the bottle) so it's much cheaper than the Floc products. 2. you don't have to turn the pump off (which stops the filtering process). 3. you don't have to vacuum the pool the next day to clean up the bottom of the pool.

Make sure whatever filter you use is clean otherwise it will take a lot longer to remove the cloudiness (if at all). A dirty filter won't clean the water, and will keep it cloudy.

The cloudy water can be caused by dead algae that turn Grey when killed.
- Adding water clarifier will speed up the process.
- Easiest solution is to swim in the pool or make the water move. Water movement will allow the filter to eliminate the dead algae particles.

Run the system for 24 hours and filter the water. Have the store test for phosphates, its food for algae and prohibits the salt cell from doing its job. Check your salt levels are good and adjust accordingly using a salt calculator.
