Hi Pool Gurus, I am in year 3 of pool ownership. I have learned so much from this forum and I thank all of you for making me a more confident and knowledgable pool owner. I have learned how to maintain, open and close my pool from all of you generous individuals. Many thanks.
Last season when we closed, I noticed a light brown "dirt" on the sides of my in ground pool. The funny thing is that during the year my water was clear but at certain angles and at certain times of the day, it looked like the sides of the pool were dirty. My water was always very clear though, no haze or apparent algae problem. I use the TF 100 testing kits and my numbers were in range for the season. The pool is a plaster bottom with vinyl sides. No liner. I scrubbed during the season but it didn't seem to want to come off with a pool brush or vigorous scrubbing in pool with a handheld brush. So now as we head into pool opening time in Ohio, can you give me any suggestions as to:
A. Is this Algae or Dirt?
B. Whichever it is, if normal scrubbing with a pool brush wont take it off, what will?
I don't want to drain all the water out to scrub it obviously.
Any advice would be greatly appreciated.
