Chlorine pH and Alkalinity Readings

by Mrs M Mcleod
(Prestonpans East Lothian)

I have a 12ft x 30in pool its been fill for three weeks now and i cannot get the chemicals levels up to were they should be my water has went slightly cloudy and my filter has been running for 16 h with no improvement please can you help

I'd like to have 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 flocs. It makes troubleshooting much easier and the process of clearing up your pool will go much faster.

Without these numbers I'm just guessing at what the problem is. Get back to me with the chemical numbers and I'm sure I can help.

Keep Pool Clean
by: Robert

Alright, we're making some progress but I still need the rest of your chemical readings, the calcium hardness and especially the stabilizer/CYA. I believe what you're using is Sodium Dichlorioisocyanurate, or Dichlor chlorine for the short name. This is a stabilized form of chlorine. This kind of chlorine is not good for regular weekly pool maintenance.

If you've been using this in large quantities the stabilizer may be too high. Or your may not be using it enough which means the stabilizer is too low. The proper range for CYA is 30 - 50ppm. Once you reach the 30ppm mark you need to stop and using regular liquid chlorine.

This is why having the CYA reading is so important. You can have all of the other readings perfect but if the CYA is too high or low it can render the chlorine ineffective which will cause cloudy or green pool water.

Right now the pH is 6.8 which is just a bit low but nothing to worry about. A little sodium bicarb can fix that. The TA is fine at 80ppm.

The reading of the CYA will tell us which way to go.

If you feel your situation is more complex than this, I do phone consultations for a donation of your choice. It makes things go much faster and many people have found it extremely beneficial, saving them time and money in the long run. All your questions will be answered. I have nothing to sell you so you know I'm not bias.

Hope this helps and have a great Summer.

Cloudy pool
by: Wade

My chess are pretty close but my pool is really cloudy can i raise my alkalinity above 200 ppm then clear the water then level it out.

Hi Wade. TA above 150 ppm is really not recommended. The right TA allows the pH to become more sable.

There could be several reasons for a cloudy pool such as bad or wrong pool chemistry, faulty filtration system, adding too many or too few chemicals, not chlorinating correctly and/or inconsistent chlorination, onset of algae, etc...

Due to this fact, I have several resources available such as eBooks that go into these details, how to fix your issues, and how to properly maintain a pool. I also have a brand new video series that teaches you all you need to know about clearing up and maintaining your swimming pool.

You can find the links to those resources right here: - Clear Blue Pool eBook - How To Clear Up A Green Pool eBook - Resources - FTA Process To Clear Up Your Pool

Have a great swimming season.
