Pool Flooded

[TulsaPool]

Need Help. I went from perfect water to a swamp overnight. Is floccing the only way to attack water that went from blue to brown. Chlorine is basically zero now, ph is 8, and salt is 2300 now after massive amounts of flooding. De filter was unable to keep going earlier so ive backwashed and now pondering what to do first. I am thinking i will turn pump on, pour DE powder in skimmer, pour in bottle of floc and waiting till morning, then vaccum to waste and then attack ph and chlorine issue with shock, then add salt? Or should i go ahead and shock with floc?

Do not add floc as it will gum up your filter. Check your CYA. Base on that reading determine your FC SLAM level and start SLAMing

 

[TulsaPool]

Cya is 50.

 

[Fast7]

So your SLAM level is 20 FC

Having trouble finding SLAM procedure on site. Sorry, first time.

 

[Fast7]

No problem.
Here it is : SLAM

I will give it a shot. I do not have liquid chlorine. I Have bags of shock. Will that work? Is there a way to know how much to add to get to 20 ppm? Sounds like i need to add acid first and get ph right and then start adding chlorine?

PoolMath
Yes, lower your pH to 7.2 before starting SLAM
Dry shock is not recommended because everytime you use it it will increase your CYA or CA at the same time depends on which type you use.
Liquid chlorine (bleach) is the way to go.

Ok i have bottle of chlorox regular bleach on hand. 6 percent sodium hypochlorite 94 percent other. Will thos work to start. How much should i add at a time to get from 0 to 20 ppm for 18000 gallon pool?

Hold on the SLAM for a bit. It is important to understand where your FC, CC, pH, TA, and CYA are before you SLAM........can you post those test results? It is conceivable you don't need to SLAM but starting with test results is the only way to find out.

 

[Fast7]

Yes, this will work.
Use PoolMath link from my earlier post to find out how much you need to add. What's your current FC?
For example if your FC is 0 you would need about 6 jugs of 6% bleach if that jug is 128 oz.

 

[TulsaPool]

Chlorine free or combined are zero at this point. Cya around 50 to 55. TA is 70, just added acid and ph is around 7.5. I also added 5 lbs of DE to filter and started running before i added acid. Thats all ive done so far.

Don't use Clorox bleach. The label says it contains Cloromax Technology. That is polymers which will create foaming and is not suitable for a pool or spa.

You need to get pure bleach with no additives, fragrences, or splashless.

Ok good to know. Is there a brand to get and where can i get it? Was thinking i need to get some kind of chlorine in pool tonight. Only other thing i have is two bags of leslies power powder plus shock.

 

[ajw22]

What is your salt level? Your SWG running? Crank up your SWG on superchlorinate while we figure this out.

Chlorine brands vary widely across the country. See if a local Walmart has Pool Essentials Chlorinating Liquid - Walmart.com or Home Depot HDX 128 oz. Chlorinating Liquid (3-Pack)-30128HDX - The Home Depot

Salt is 2300. Not produccing. I can add two bags and get it where it needs to be now i suppose. I turned it off to slam.

Add the salt and get it going while you find a chlorine source.

 

[TulsaPool]

My walmart down the street says it has that in stock. Will go get some. Says above i may need about six jugs. How many should i add tonight?

 

[ajw22]

This may be more dirt then algae. If you get the chlorine back up it may just take a bunch of filtering to clear the dirt out. May not need a full SLAM Process

When you can get 4PPM of FC in the water with the SWG or LC then see what CC's you have.
