I tried using some Vit C tabs on the steps with no visible affect.
any idears
It's probably not related to your staining but your FC is way too low. Your FC should be at 5-8ppm continually to keep your pool troublefree.
I agree that it looks like calcium precipitation but your test numbers, while just a little bit high, would not indicate calcium is your problem.
Do you feel like you have had pH up in the 8's?
Yes I belive the PH has been in that area for a bit.
Have you recently drained a portion of your pool water and refilled?
No, usually just keep level up via rainwater
I assume you cannot remove the stains by brushing. Can you get hold of a tri-chlor puck and hold it against the stain for a minute or so? If it's organic (not calcium) the tri-chlor will start to diminish the stain.
Brushing seems to have no effect, I will try a puck, though I don't think its organic as we usually keep the chlorine
levels up
Do the stains feel rough to the touch.....indicating calcium?
slightly rough, but hard to determine as diamondbrite surface is a bit rough to begin with
Describe in detail what you've done to get rid of them to this point and whatever you can tell us about the characteristics of the stain and we'll go from there..
