Hi all, I was an avid reader and follower of TFP for some time when I bought my house with pool in 2016. I had everything super under control and water was sparkling like glass. Unfortunately life happens and disappointed to say pool maintenance became less of a priority. I continued to struggle with fine dust (here in Arizona) forming into almost like a mud at the bottom of pool and not being filtered out. No matter how much I vacuumed, cleaned cartridges, and repeated I could never get it all out.
I bit the bullet last weekend and drained the pool and refilled for a fresh start. Currently sparking clean and want to keep it that way again so I am back on the TFP wagon!! Unfortunately though I’m stuck with some stains on the bottom (tanish) of some sort in many spots. Hard to see on the picture below but you can if you look closely through the blue water (I pressure washed, scrubbed with chlorine tablet, scrubbed with pumice stone and couldn’t get any spots off).
Can anyone help identify what this might be and how to remove it from the surface of the pool? I’ll try and get a better picture and upload to the thread
Before I forget here are my chemical levels (using TFP recommended kit)
FC 4.5
CC 0
PH 7.4
TA 90
CYA 30
Temp 82
