Thank you pool doc!! Your the best.....

OK Ben here is what I got.

TC 15
CC 0 ( I just tested this today and thats what I got. 5 drops of the oo3 reagent did not make the 10ml sample turn pink. Stayed clear)
PH 7.5
Alk 40 ( First time I checked it today. Added about 70 oz by measure of baking soda today to raise.)
CYA 30. ( I am guilty of adding CYA when I opened to get this 30ppm. So that may have added to my issue but its at 30.)
Hardness 17.1 ppm. ( I test this with the Hach 5b total hardness test kit I use to test my well water hardness. Its powder based.)

I have been running two filters in series on low speed. Cart first then sand. The cart filter is a new unicel from purchase last year from amazon. The sand is newer also. I am not really catching anything. The pressure rose 1/2 psi to 1 psi maybe.

I am using K mart brand 6% bleach or pathmark food store 5.25% This is the k mart. The one I got has 33% more for free and is 128 fl oz.

$1.66 gallon. I bought the whole shelf.



Its blurry but says 6%



The pathmark home basics stuff has no percentage and is always $1.65. I assume its 5.25% from what my tests show on Cl levels.



Let me know what other info you need.

It took me a long time to go through this thread.

1. Remove the sand filter.
2. Run the pump ONLY on low speed.
3. Add chlorine ONLY in the evening. Brush the pool after adding chlorine.
4. Don't add ANY thing else UNLESS you need to add borax to raise the pH or acid to lower it: if the pH is between 7 and 8, leave it alone.
5. EITHER add DE to test your filter OR get a new Unicel.
6. Do NOT clean the filter unless you are seeing at least a 3# increase on low speed.
6. Report AM FC and CC AND filter pressure 1x per day; no other reports.

I really wish you'd get a new cartridge, if you can. Do the DE or a new Unicel -- MUST have Unicel name on packaging! I'm finding many, many cartridges are NOT what they are sold as.

Also, the next time you clean the cartridge, please photograph it -- outside, inside tube, caps.

Good luck!

The cart is new Ben. I took a few pics lost some from technical error on the phone.

These pics survived and I can tell you that it is one season old. The original filter lasted 6 yrs. Inside there is a spoked wheel in the center to prevent collapsing.


If you specify I can take any pics you want next time I open the filter.









I took the sand filter offline in my series configuration and am only running the cart on low.

#4 I think you mixed up the borax and acid application.

#5 the DE for test purposes will not clog the cart?

Filter pressure is 5 1/2 psi. 5 psi is start psi clean

Last night

PM: FC = 18n
AM: FC= 15
AM: CC = 0
Filter pressure 5 1/2. ( Same as yesterday)

On low speed 24/7. Will only add bleach at night per your instructions.

Today steady rain.

Last night

PM: FC= 18 ( Brought up from 13 to shock level. Was sunny later in the day yesterday)
AM: FC 15 ( Losing the same overnight 3 ppm.)
CC = 0
Pressure: 6 psi ( went up 1/2 psi. Just a hair shy.)

Steady rain today again. Two weeks and 2 days into this cleaning process. About 36 gallons of bleach added so far for 6000 gal pool.

Note:

Trouble I have testing CC even though I am fast, is that the sample changes back to pink very quickly after turning clear. I cant get the 003 reagent in there fast enough to really test. I have to add a substantial amount of the #871 to get it clear. Then the #003 does nothing.

Same as yesterday morning.

FC 15
CC 0
psi hair shy of 6 psi so not rising after 24 hours.

( I dont think its a filter issue. Its either slow to kill or too small to filter)

Can see bottom of pool but cloudy still.

I don't think its the CYA thing with the ammonia. I will re read the cloudy pool section. There needs to be a different cause for my cloudy pool every year. perhaps I am lacking something. Possible because I have 0 hardness to the water and I need some calcium?

Ugggghhhhhh!!!!!!

No, you do not need calcium.
