Pool opening, water is green, what shall I throw in there?

You can test CC every time you do a FC if you want. Just don't test pH until you are done with the slam and your FC drops below 10ppm. Here is a link to the test to know when you can end the slam: Pool School - Perform the Overnight FC Loss Test (OCLT)

Keep your FC 24 until all three of these things happen:

1. your water is completely clear. not almost clear. not a little cloudy. clear...like crystal.
2. the CC is 0.5 or less
3. overnight loss is < 1 ppm

Are you brushing daily?

Thanks for the nice posts guys!
One more question. So I keep this 24 FC number going for how long? Until the pool clears? When do I start testing for CC? When do I do that FC loss test?
Ok that was 4 questions, I apologize

Thanks again

Pat

You are doing great so far! There are 3 criteria listed in the SLAM procedure that you should meet before ending the SLAM.

1. CC is 0.5 or lower
2. You pass an OCLT (ie overnight FC loss test shows a loss of 1.0 ppm or less)
3. The water is clear

Keep your FC at our just above 24 until all three criteria are met. If you don't meet all 3 criteria there is probably some algae hiding somewhere.

I generally test for CC every time I test FC.

I am pretty new to this, but based on the other posts I have read, most people seem to wait until their water is clear (or mostly clear) and CC is 0.5 or lower before doing an OCLT.

Thanks to the last 2 posters I got it.

The more often you can add chlorine to stay at your target, the faster it will clear. Good luck!

It's going great, the water is not clear yet but it's blue, not green anymore. I will look into brushing it too.

Brushing does a lot of things, but during your slam it is really important to do it at least daily. Algae develops a biofilm to protect itself and brushing kind of scratches it open so that the chlorine can get inside and do its job.

 

[kimkats]

Brushing stirs up all of the old algae so the filter can catch it.

The color change is good! Have you been taking a picture a day? That is VERY helpful for you to see the changes as they happen.

No I haven't been taking pictures sorry.

Thanks

Ok so everything seems to go fine. I keep testing the FC and adding bleach as needed to keep it at 24. Just for fun today I tested CC and figured it would be high but I got a number of 0. How is that possible, isn't the FC becoming CC?

Thanks

CC is oxidized by the sun and FC.

So 0 is normal?

 

[kimkats]

CC of 0 is GREAT! It means your FC is working! To know when a SLAM is finished one of things your look at is Is the CC .5 or less? If it then you passed THAT part (there are three parts).

Wow that's good news but the water is still cloudy. So not done I guess.

That's correct. Sometimes one (or two) of the 3 SLAM criteria can pass, but one is stubborn. That's when you just have to be patient, continue everything on the SLAM page and press-on. Eventually the algae will be eliminated, you'll pass all 3 criteria, leaving you with nothing to do but sweep & swim.

HI - Two cents worth - you need to clean your cartridge filter everyday to remove the stuff that has been filtered out. You are going to get there, Been there, done that.

[vaindioux]

OK on cleaning the filter cartridge. Good news the water is getting clearer. I can finally see the bottom of the pool.

Thanks

Progress is good. Now you're in it for the long-haul. Keep some bleach nearby, check FC on a routine basis to bump-up FC, and press along with your day. Scrubbing and filter washes are a good thing. Good you're doing it (SLAM) now. Warm weather is approaching fast.

 

[vaindioux]

Wow

Getting impatient here now. I have been slamming for 14 days and still not done. I am adjusting my FC daily to my target of 24 and cleaning filters. Water is definitely getting clearer. With a water temp of 77 degrees I am itching to get in the water.
How much longer do you think?

Thxs

Really hard to tell. At least you are seeing water clarity improvement. Have you verified your CYA lately just to be safe? Just to make sure your FC is at the correct (optimal) performance? I didn't go back to the beginning, but have you revisited any items in the water that may be holding any residual algae (i.e. ladder, light niche, etc)? Still scrubbing the pool interior each day? 14 days is a long time. How about a pic so we can see the progress?
