UPDATED: With NEW K-2006 Numbers: Where to start with SLAM??

Keep running the pump and keep the chlorine up. Clean filter (backwash for sand) when the filter pressure is 25% above the clean filter.

thank you. have been continuing this after your recommendation and ajw22! still waiting on test kit-got an email that it was delayed. so still waiting for more info! thank you for helping so far!

Hello everyone!
I finally got my test kit. Here are my readings:

FC: 1.5
PH: 7.4
TA: 80
CH: 180
CYA: 30
I still have a bit of residual on the floor of my pool that “poofs” when I turn filter on high, or when I brush the bottom. What would you all recommend I do next? Thanks so much!! I also got 6 gallons of liquid chlorine (can get more if needed), and have a total of 12 lb of CYA.

I doubt you have mustard algae but we will see...

Mustard Algae

Today We are going to show you how you can get rid of mustard algae in your pool. By following the steps in this guide and with no expensive chemicals.

Brushing daily breaks the biofilm on the algae and lets the chlorine attack the algae. The chlorine will be more effective with frequent brushing.

Hello!
I got new test kit in! I checked all levels yesterday and posted, added 2 gallons of liquid chlorine 10% last night, and today my FC was 6, cc 0.5, and CYA is 30, with small film specks on water surface and still what I assume is dead algae at bottom.
My slam math was to add 4 lb of CYA to bring that to 45, and then add 3.5 gallons of LC to bring it to 20. Does that sound right? And if so, I would stick to SLAM until I meet all 3 criteria?

And if so, I would stick to SLAM until I meet all 3 criteria?

Correct. Would have been best to leave the CYA at 30 but what is done is done. Maintain a FC level of 20 ppm until you pass the three criteria.

 

[srm0112]

What’s confusing is even when I fill up the tube, I can clearly see the black dot at the bottom (with the K-2006), but it says to put 30. I would guess it was 0.

 

[mknauss]

I thought you said you tested a CYA of 45. My bad.
So you are not testing at a 30? If you can see the black dot, it is less than 30. Have you added any CYA?

 

[srm0112]

It’s ok! Where it says to read the number, mine was 30, but I can see black dot easy. I hadn’t previously added CYA at any time.

I am currently at “30” although I think it’s less, and added 4 lb. I think I will then have a real reading of 30. So trying to figure out what’s going on here and just need someone to help with that part lol whole new world for me!

 

[mknauss]

Where it says to read the number, mine was 30, but I can see black dot easy.

With that, and if no CYA had been added, then it is zero. CYA does not exist naturally in water. You must add it.

 

[srm0112]

Ok. So I need to add a total of 6 lb of CYA to bring my ppm to 30. And then SLAM based on that to get to get to 12 FC, and maintain that.

At a current FC of 6, I also need to add 1.5 gallons of LC. Just making sure my math is correct!

 

[mknauss]

Correct.

 

[srm0112]

Today my numbers are good. 35 CYA, 14 FC. When would I add more chlorine? If I check tonight and FC has dropped?

 

[red-beard]

Yes

Hello algae fighters! You all have been a big help! Attached is our pool from this past Saturday evening. My only question now that I finished SLAM... there is still the smallest bit of dead algae. I stopped SLAM after I met all 3 criteria. It rained the last 2 days, so Should I just keep brushing and letting it filter out? Or pick SLAM back up to ensure it is in fact dead? CYA 50, FC 7, CC 0 today.

 

[red-beard]

Just keep running the filter pump
