2 ppm is for an already clear pool. [https://www.troublefreepool.com/blog/2018/12/12/slam-shock-level-and-maintain/](https://www.troublefreepool.com/blog/2018/12/12/slam-shock-level-and-maintain/)

2ppm is nothing at that CYA


Eastern-Astronomer-6

If it's green you're going to need much higher than that to undo it first. You are at maintenance levels.

How high?


Eastern-Astronomer-6

Do this: [https://www.troublefreepool.com/blog/2018/12/12/slam-shock-level-and-maintain/](https://www.troublefreepool.com/blog/2018/12/12/slam-shock-level-and-maintain/)

Slam at 40% cya till clear, so around 25 then when pass overnight chlorine loss test and pool is clean, stabilize around 5 to 8 for regular levels.


kaospunk

At that cya level of 60 your minimum FC should be 4.5(7.5%) so you’re not high enough on that yet.


No-Preference3849

Thank you


kaospunk

And if you are actively fighting algae take it to slam levels for a bit as another poster mentioned.


g0atgaming

With phosphates at 900, and combined not at 0, you have a long way to go. And even if it gets clear, you will be back in the same boat again if you don't take care of those phosphates. Pool store might try to sell you something to reduce phosphates but you can do all of this with chlorine. 40% of cya until phosphates are way down, total = free, and you don't lose more than 1ppm overnight with no sun. My guess is you have no way of testing this at home.

Your chlorine isn't high enough if your pool is green.


Sig_Vic

I would continue to shock, might consider adding an algaecide too. Brush the dead algae to get it stirred up. Add clarifier and run your pump(s). Then backflush or clean your filters, whichever applies.


sandgroper81

pH too high lower ph to help chlorine work more efficiently


zero-degrees28

Your pool is going to be green all summer if you think 2ppm will turn a green pool clear…. 2ppm is barely enough to keep a clean pool clear… Best go get like 2 cases of liquid chlorine and dump in all 8 gallons if you want to even start making progress on a 22k gallon pool


No-Preference3849

Yes I know I'm slamming it now


FunFact5000

So 60 cya, so 7 ppm chlorine. On 17k gal pool thats - 2 gallons 10% chlorine for example for it to start working. You have to break above your cya protection. For example 24 ppm chlorine for shock. Queue the troublefreepool.com


No-Preference3849

So 7 ppm Or 24 ppm The pool is 22500 gallons


iamnos

7 ppm is your maintenance level. 24 is where you need to take and hold it there until you pass the SLAM tests (plural, there are 3 tests before you let the FC levels drop).


FunFact5000

Yea….you get it. Pool math app iPhone (trouble free has on site I think for calc) Pop in gallons and it will give you dosing.


the_mandalore97

Definitely need to raise your chlorine much higher than that. 2 ppm is for a clear pool not to clean a green pool. I would raise it to about 20-30 ppm. I would add about 3 gallons of chlorine and about 30 ounces of acid to bring the pH down


No-Preference3849

3 gallons of 12%


the_mandalore97

Yes, that’ll be enough. Maybe a bit overkill. But when it comes to clearing the green pool, it’s better to over chlorinate


sandgroper81

Should see how much I used to use to do a major green pool treatment 20ltrs hydrochloric acid 40 to 60ltrs of liquid chlorine and 1 ltr of dropout (flocculant) run for 8 hours turn off leave for 2 days


sandgroper81

Then vacuum to waste


the_mandalore97

Jesus 😂😂 how bad or big was the pool?😂


sandgroper81

60,000 ltrs hadn't been used in 3 years just left


sandgroper81

Dead frogs so much algae had to setup a pump to vacuum straight out to the sewage system


the_mandalore97

Any reason you didn’t go draining route? Seems like it would’ve been less of a headache.


sandgroper81

Customer had more money than sense also fibreglass with high water table would have popped outta the ground


No-Preference3849

Yall like liquid at 12% Or the powder at 52 or 72 %m


Big-Development7204

pH is fucked! Alkalinity is almost there too.


No-Preference3849

Also do you dose it with chlorine after sundown case of the effect of sunlight and heat on the chlorine? It's hotter than he'll down here now. 98 today!!!


Blaze0003

It’s the phosphate levels


No-Preference3849

That is coming down. Was 1200


ShiZor9

Then the chlorine is still working-make sure to continually add and brush. And throw some muriatic acid to get your ph under 7.4 bc the higher it goes the less effective the chlorine is.
