pressure washing runoff

[JoanC]

Good morning!
Sunny and hot here in northwest GA!
I searched the forum for about 30 minutes for an answer and gave in to posting.

We’ve been pressure washing our older concrete pool deck and some of the nasty water has gotten in the pool despite efforts to prevent such.
The black muck settles in streaks on the liner and we Vaccuum just to have it come back out the returns and settle again.
I fear this will stain if not removed soon as it has to be partially from all of the trees we have.
Should I simply increase FC to shock until it’s gone or another thought was add a little DE to my sand filter to help it filter better? Maybe both?

If yes on the DE, are there instructions on how much and how to add it somewhere on the forum? I have to admit I’m cautious about inhaling that stuff.

Numbers have been fine except Ph keeps running back up to 8.2 or hot pink!

Thank you!
Joan

I would go with both. Here are the DE notes:

Add DE to a Sand Filter

A clean pool filter will increase the efficiency of your pool! ... your filter are to backwash it, clean the manifolds and grids, and add new DE.

Thank you @Texas Splash, for your help and for the link!
Hopefully I did the @ thing right ?. Grandma still trying with the new site!

Anytime I pressure washed around the pool in the past I raise the FC to SLAM level before I begin. I just figure I'm going to be sloppy and get stuff in the pool.

@tim5055 that’s exactly what I did! ? I knew some would get in the pool no matter how hard we tried to keep it out so I “pretreated” so to speak.
Our concrete was black! Hadn’t been cleaned in two years. The remaining residue in the pool would have been much worse had I not raised the FC TO SHOCK LEVEL.
Thank you for mentioning this because it will help others as well as you’re trying to help me!

I was the second owner of the house and whomever pourd the pool deck must have been new with concrete. In two spots anytime there is a lot of water (heavy rain/power washing) the pool deck flowed into the pool. There is no avoiding it.

That stinks about your cool deck. I know it would be expensive to have it remedied. Our neighbors just plunked down about 15k for new pool deck that is not very large areas. Biggest part was ripping out the old.
