Cloudy pool, help!!!

[goodyFH]

Backstory: Bought house with pool in January. Got it going good with yalls advise. I bought a stenner pump and a drum of chlorine. its been going good.

I go on vacation last week, i thought i had plenty chlorine in the stenner but i was wrong. Got home saturday to a very green pool.

I poured a bunch of chlorine in and the next day its not green but very cloudy.

So ive been adding at least a gallon everyday and its still cloudy, i actually got out the tablet holder and put it in there with 4 3"tablets in it

I read where it could be the ph, so i got some muriatic acid today
My test results when i got home from work were:

FC - 0 , last night it was around 10
pH - above 8, 7.5 after adding half gallon of acid

so i add 2 gallons of chlorine to shock, now my readings are:

fc - 11
ph - 8ish (i read its not very accurate during shocking)
TA - 140
CH - 100
CYA- 30ish

I have 14000 gallon above ground with sand filter

What should i do???

I havent tried brushing walls or floor, but it doesnt seem dirty just cloudy but that could just be ignorance

What should i do???

You need to stop everything and pronto. Tabs raise your CYA which makes you need more chlorine to achieve the same sanitation.

Read up on SLAM Process
Fire when ready.
we will help.

So this what i gathered...

-Take tabs out
-check chlorine levels multiple times a day and add to shock level, would morning, lunch time, 5ish, and then 10ish be good?
-i have a robot vacuum, should i run it now?
-basically its gonna take a week

What else?

How’s your filter? Is it clean? I don’t know much about sand filters but I read people need to occasionally replenish or replace the sand.

Take tabs out

Check

2 hours is best. The more you ‘M’aintain the quicker it goes. Do the best you can of course.

have a robot vacuum, should i run it now

Sure. Brush and vac/robot daily. More if time allows.

basically its gonna take a week

Many times yes but all pools and particularly their filters are different. First you kill the crud and then you wait as the filter removes whatever didn’t dissolve.

What else

Lower PH to 7.2 with MA. If you are really high above range it may take more than one add to be back in range.

Backwash the filter at 25% rise in psi.

keep reading the slam guide.

ask away with any thoughts.

i just tested it again, it was down to 10 so i added to get to 13.
is pH reading reliable right now?

 

[Newdude]

No. 10+ messes it up. You can let it drift down to 9.5, See/fix the PH and then hit it hard.

filter got cleaned out and new sand beginning of season so i think it should be good,

i backwashed some earlier today and it was clear. does that mean i didnt backwash long enough?

ok, ill check it in morning before adding chlorine. thanks!

Matter of fact the original PH in post 1 probably isn’t that high because of the 11 FC. Sorry I missed that until now.

ok cool, i added a quart at lunch around 230 today and it got it down to about 7.8-8 then another quart after work brought down to 7.5ish before i started heavy with the bleachy stuff

 

[goodyFH]

pool is back to normal, thanks everyone!

 

[Newdude]

To be thorough (on your behalf), you passed all 3 criteria, correct ?

Clear water
Pass Overnight Chlorine Loss Test
CCs less than .5

We don’t want you to be doing this again so somebody will always gently remind you just in case.
