Refilling pool

[Ymh]

I should backwash ASAP?

As an aside, would you mind explaining to me how thebackwash helps for the grayish stuff in the bottom of the pool?

Great. Thanks. And the de?

Are there any numbers on it? Pro-grid has several sizes.

Backwashing removes the filtered particles from the pool water system, so the chlorine can work on stuff "in the water" and not just what the filter has trapped
It mostly helps to slightly lower your chlorine requirements during SLAM and even maintenance.

Backwash has almost nothing to do with debris on your pool floor. Backwash cleans the debris from your filter and is essentially unrelated to conditions that exist in your pool.

Do you recommend a backwash during slamming?

Slamming update. So far chlorine is staying pretty steady and no ccs. Water itself is crystal clear. But there is some gray dust on the bottom of the pool.
How to proceed?

Be sure to follow the SLAM Process steps, some have to be repeated over and and over again, once you don't have "stuff", then you can attempt the Overnight Chlorine Loss Test <-- instructions

Only if needed (and it often is....sometimes more than once). You backwash your filter when the psi rises by 25% whether you are SLAMming or not.

Reread the SLAM article......it tells you that.

The inside of my inline chlorinator...

I have it set to off. Is this okay?

Is that foam or hard (don't touch it with skin), Was it loaded before you started adding liquid chlorine? Is the outside hot?

 

[Ymh]

Hard. I don’t think so. Not hot. I put the Liquid chlorine straight in the pool.

That's good! Please don't pour liquid chlorine in there! I meant did you shut it off w/tablets in there, when you starting using liquid chlorine in the pool?

 

[Ymh]

No. Don’t think there were any tablets. It was off for awhile

Slam update. Fc is steady for nearly two days with very slight changes for evaporation. No ccs. Water crystal clear. There is some dust on the bottom of the pool But in my vacuum all I see is de.
please advise

 

[Ymh]

It’s a very small amount of dust.

You may need to slowly inspect your filter grids, there may be damage that is allowing them to leak (it could be very small)
Can you hold a sock over one of your returns and see if you catch anything in it?

 

[duraleigh]

You are SLAMming right now, correct? Focus on your SLAM.....do not worry about your grids for now.

That "small amount of dust" you see on the pool floor is almost surely dead algae as a result of the high FC. Simply vacuum it up into your filter or brush it up into the pool water and it will, in time, disappear.

Evaporation has nothing to do with your SLAM or FC level at any time.

Can you post a current set of test results?

 

[Ymh]

What should I test for?

I meant sunlight. What should I test for? Just fc and cc?
