Yellowish dirt

[Barry J]

Lately I've been getting a yellowish dirt build up on the bottom of my pool, not on the sides but kind of scattered, anywhere the return does not directly flow.
It wasn't there a month ago, I think June/July I only had to vacuum two or three times, now it seems I vaccum it up and then the next day or two It could use another vacuuming. It's almost like a sand.
My kids are not in it as much but seems like more build up.
I tested the water and my chlorine came back good, pH was about 7.5, and alk was 7.
Any suggestions
thanks
Barry

You know the Mods are going to want numbers...I assume you have the Taylor K-2006?

Yep! What Charlie said!

[Barry J]

Gave the numbers I have, chlorine, ph and alk.
What else??

Can you touch it? If you can touch it, try to pinch some between your fingers and look at it out of the pool. Does it feel like sand or is it of a more fine consistency than sand?
If you can't touch it, does it seem to disappear when you try? Are your walls or floor slick or slimy to the touch?
Is your water clear or other?

You didn't actually give a number for chlorine. Only that it "came back good". How are you testing? Using strips, OTO or titrating drop kit?

Sorry for all the questions but it's hard to give you an answer with such little info.

I'll go into pool later, but for now, the kit I'm using is a HTH kit, ..OTO and the chlorine by view looks to be 5 or higher, water is clear.
Do I have too much chlorine in???? Did I need an algaecide or just shock and if algaecide what type???
Thanks
