Can't Get Clear (Have PS233 Results)

[aswetich]

Ok,
One person says to keep the CL (Is this TC?) at 20 ppm and one says don't go below 3.5 FC. I am assuming they say the same thing so I will ask the question I have related to the bleach calculator. The bleach calculator has a ppm increase field but I don't know how to calculate what my existing ppm is. Can you tell me how to use my numbers above to figure out the current ppm so I can enter the ppm increase in the ppm calculator ?

Thanks

You don't calculate what your existing PPM is, you measure it with a test kit. Measure the FC with the DPD-FAS test. If you want to get to 20 ppm Cl, and your test results are 3.5, then 20 - 3.5 = 16.5. Put that number in the ppm increase field and hit calculate. You'll be shown how much bleach to add.

That is what I calculated but I assumed I did something wrong. My 32K pool will require 8 Gallons of 6% to get to 20 ppm. With the readings I displayed above does 8 gallons seem correct ? What number do I want to use to keep at 20 ppm ? FC, CC, or TC ?


Thanks

If you are currently at 5 ppm, then yes, 8 gallons of 6% bleach will take you to 20 ppm. However, if you have 3.5 ppm right now, you are going to need 8.8 gallons, or 8 Gallon(s), 3 quart(s), 0 cup(s) and 6 ounce(s).

For sanitation/algae killing the number that does the work (the one you want to use) is FC.

OK,
This is all starting to make sense. So after I get everything all cleared up I should keep my FC level around 5 due to the 60 CYA ? (Any span or just right at 5 give or take?) If I keep my FC at 5 won't the standard two tube tester show the clorine level off the chart ? (Bright Yellow) If it is off the chart wont it irratate the eye, Etc ? Having you guys to talk to is helping a lot !!! Thanks

Yes, keep it at right around 5 to be problem-free.

No, you won't get any eye irritation.

Yes, it will look like it's off the chart. That's why you need a DPD-FAS Cl test, much like the one that's included in Ben's test kit. Actually, the PS234 is the best deal out there, I highly suggest it.

Last night about 9:00PM I added the amount of bleach the calculator said to bring the FC up to 20 ppm. Just checked the FC at 10:00AM this morning and it is 20.5 ppm. It is a bit clearer but still has a long way to go. How long should I keep the FC at 20 before I let it drop down to the 5 ppm recomendation for my 60 CYA ? How long should it take to clear up ?

Thanks

Run your pump 24/7 'til your pool looks good to you. Keep your Cl at 20ppm for the same length of time.

Can't tell you how long that will take...usually a dramatic inprovement in 24-48 hours.....depends on a lot of factors.

Can you test for CC?

Hello all. Please allow me to chime in here since I also have similar problems posted in this thread. First, my pool is 14x28 vinyl IG, 12K with sand filter. After discovering Pool Solutions late last year, I decided to convert to Ben’s methods. Upon opening this year (4-23), I was amazed how fast the green went away in the pool water using 6% bleach. While waiting for the PS234 to arrive, all I have is the OTO cl and ph and so I don't know where my cl level is above 3ppm. The green has been gone several days and I've brushed and vacuumed several times to ensure I've killed the algae attached to the surfaces. My problem is heavy white cloudy water. From past experience, I assume this to be dead algae, but flocking didn’t settle it. Other than after flock app, the pump/filter is running 24/7 and I've cleaned the sand with last year's pool store filter cleaner. I don’t understand what this milk effect is, which reduces visibility to one foot or so. Any suggestions please? Thank you much!
