It's a new year and I have the same problems. Please help.

I think you have the strength set to 6% instead of 10%. You should need 1.75 gallons of 10%. Just estimate the 3/4 gallon, no need to be exact.

Thanks for catching that for me. Ok to add this all now, slow pour in front of the return?

 

[jblizzle]

Pour away!!!

I'm still not clear on the brown substance at the bottom of my pool. It moves easily if brushed and comes up with my robot cleaner. 12 hours later it seems to settle back in the same places. Could this be brown mustard algae and what you are referring to as 'fighting something'. I'm new at this.. just wondering.

A CC above 0 generally means that your chlorine is interacting with something in the pool. It's hard to say if the brown stuff is algae, or piles of pollen, or something else. Either way, a SLAM is in order.

Just to make sure, you put 10℅ bleach in the percentage on pool math.. If so, that is correct and start your slam, the first addition is always the most...

I am using my phone so please excuse any spelling errors and short response.

I put in 2 gallons of 10% liquid chlorine. The reason I went a bit over was because these 2 bottles were in my basement from last fall. I have another 10 bottles in my garage less than 1 week old.

 

[jblizzle]

Good plan. You can retest the FC and CC in 30-60 minutes. That might have been some pretty weak stuff.

 

[jhuehne]

Fc = 9
cc = 1.5

 

[jblizzle]

Put the 9 in the FC Now column, Target still 16 and add more chlorine.

 

[jhuehne]

Done with fresh stock. I'll check levels again in the morning. It's raining pretty hard again.

 

[jhuehne]

Still raining. Just re-tested;

FC 15.5
CC 1

Add more chlorine and try to follow the steps here: Pool School - SLAM - Shock Level And Maintain

?

Brush the pool and drain some water? Water is at the top of the hole on my skimmer now.

 

[cowboycasey]

Prefect, brush and drop some water

[jhuehne]

Just brushed, pumping to waste to lower the level of the water. I re-tested afterwards and I'm at:

FC: 16
CC: 1

Should I still add more liquid chlorine? I removed my solar blanket to clean/brush. Should I try to put that back on?

 

[cowboycasey]

16fc is perfect for your CYA level (CYA 40) Pool School - Chlorine / CYA Chart

I would leave the cover off, when they are on it likes to hold the CC's

 

[jhuehne]

Fc = 13.5
cc = 1

I added more LC as instructed by the calc.

 

[jblizzle]

 

[jhuehne]

Tested it twice:

FC = 14
CC = .5

FC = 14.5
CC = 1

I'm going to put in some more LC and see where it is at in the morning. The brown stuff is still in the bottom. Water still looks clear.

 

[jblizzle]

The brown stuff is not just going to disappear, you have to scoop or vacuum it out (assuming it is not a stain).

 

[jhuehne]

I should have clarified that I sucked the brown stuff out of the pool (or tried to) this morning when I pumped to waste using a pole, brush, tube to skimmer basket. The areas I removed it this morning had it again tonight when I just rebrushed the pool (without a pump to waste since water level is ok). It could still be a pollen that is blowing in since it is uncovered. -shrug-
