Can Super Floc Remove Pool Algae?

Will raising the pH level and adding Superfloc (that is supposed to coagulate waste to the bottom that can be vacuumed to waste) get rid of algae?

Thanks for the question

As you know a floc, or pool flocculant, helps coagulate, or clump, particles together to make it easier to either filter or vacuum out of the pool.

If you have pool algae or solid green pool water, the best way to get rid the algae is to shock the pool. This is what kills the algae, not the floc.

Swimming Pool Algae

Green Pool Water

Any pool algaecide is used for preventative maintenance only, not to get rid of algae.

Now, you can use a good floc for cloudy pool water or a green algae swimming pool. Many people may think, or are told, that adding a bottle of something will cure a pool problem, but unfortunately that's not always the case.

If your pool is green, or cloudy, or whatever, it will take time and effort to get it back to normal.

It's always best to stay on top of things, test your pool water twice per week, and take the preventative steps necessary in order to have a great pool all season long.

Hope this helps and have a great and safe swimming season.

Flocculants Hiya

by Ken

Hiya I live in Spain for 6 moths of the year, I have come over and my pool was green that has been resolved. My pool is 8x4. It is still cloudy with like white bits floating round the pool. I was advised to Floc, this I did run the pool then left it to settle. I woke up in the morning and yes it was all at the bottom of the pool. I hoovered the pool and now I have bigger like white fluffy bits instead of the smaller ones I had before I used the floc. Is this a problem or could you advise a remedy to solve the issue I would greatly appreciate any help thanking you in anticipation.

Hi Ken. It's obvious that you already know there's something going on here. Most intelligent pool owners like yourself can identify a problem. You've used flocc and realized what it does. I'll simply connect some dots for you.

Floccs are great when needed, but they don't identify the underlying issue. I need your complete chemical readings, the actual numbers:

Chlorine, CYA (cyanuric acid/stabilizer), pH, Alkalinity, Calcium Hardness, and Metals (iron and copper) and names of any algaecides you may have used along with clarifiers, phosphate removers, and/or floccs. It makes troubleshooting much easier and the process of clearing up your pool will go much faster. I also will need your filter kind.

There could be one or a combination of thing going on with your pool and dozens of reasons why a pool can go cloudy. For a more thorough understanding pool water chemistry I also offer eBooks. They're very detailed and can offer much more information than can be contained in a couple of emails.

Cyanuric acid levels are pretty high in my pool

by LInda

All of my chemical levels have been right where they need to be , the only change i have made is added an algaecide last week and today the chemical levels are where they are suppose to be except the cyanuric acid. My question is would the algaecide have caused this increase ??

Hi Linda. Some algaecides do contain a stabilized form of chlorine known as sodium dichlor. It is in lesser amounts than you will find in straight up granular dichlor chlorine.

A few ounces of CYA laced algaecide will not cause a huge rise of CYA in a 20k gallon pool. That would take several quarts.

If your stabilizer is high, 70ppm or above, chances are you're using stabilized chlorine as your main source of chlorine or overusing chlorine tabs. You should only be using liquid chlorine or bleach for weekly chlorination. This will take care of 99% of your chlorine needs.
