Help a CANUCK

[CANUCK]

Can you believe that after the 12 liters of 6% bleach, OTO being as dark as a pale ale, I woke up this am to a yellow line at the bottom of the pool?
Ben – do I release the hounds and add another batch of bleach. My PH seems to be in the right area.
Suggestions?
Thank you,
Christian

Are you sure it isn't pollen? Raise the chlorine level back up this evening when the sun is off the pool. An hour later, test the chlorine. You can force your kit to go higher with a dilution method explained here: Testing Without a Good Kit

Test again in the morning within two hours of sunrise. If you lose no more than 1ppm of chlorine overnight, then it most likely is not algae.

Good question on the pollen versus algea.

Pool looks better but still not great. Chlorine is high. I will get water tested again and report back. You guys aren't kidding about pool stores, they have no clue. I am fortunate to have 6 pool stores within a 10 km radius and the'ry all trying to sell me the entire inventory.

Latest numbers:

Free Chlorine: =>10 ppm - They cant measure > 10 ppm
Total Chlorine: 10 ppm - They cant measure > 10 ppm
Combine Chlorine: 0.0 ppm
pH: 7.8 ppm
Hardness: 170 ppm
Alkalinity (w/ stabilizer correction): 60 ppm
Cyanuric Acid: 35 ppm

Pool looking better but still needs help.

Use your OTO kit and test it yourself using the dilution method from post#12. That way you'll be able to go higher than 10ppm with the testing.

See what happens overnight like I explained above. I have a feeling it may not be algae, especially with a CC reading of 0.

7.8 is the outside of the recommended pH range. You test it with your kit and see what you get. (BTW -- What is the highest that your pH tester will read?)

If you lose no more than 1ppm of chlorine from sundown tonight until within 2 hours of sunrise tomorrow, it is unlikely that it is algae.

Run the pump 24/7 while you are trying to clear the pool.

Water looking much better. Tried dilution method with a three-to-one but it's still high. i'm thinking about 12 ppm.

The pool is looking amazing though. My highest PH measurement goes to 8.4.

Thanks everyone,

Christian

Ok. The reason I asked how high your pH tester will read is that some testers only read to 7.8 so on those kits, a reading of 7.8 could actually mean higher than that with no way to differentiate. Since yours reads up to 8.4, then we know you reading actually is 7.8 which is fine.
