Light Brown stained vinyl liner everywhere but under wedding cake pool steps

Thank you...I will try soon, maybe later today. So, I noticed that you did not mention brown algae or something along those lines...is that due to the water being clear, the fact it cannot be brushed off of the liner with just a brush or my hand or is there another reason for the fact that it is probably NOT related to an algae problem?
Thanks again.

Right. As far as I know, you can always *feel* algae on a liner pool, by touching the liner. And brown algae (not that common), can be at least partially brushed away.
