First time home buyer, pool help needed

[fatboysam]

I bought a house last week, I am a first time home buyer, and I am having tough time figuring out how these things work.

I see some stains at the surface of the pool, I don't know how to get rid of it, I tried using a brush, but without any success, I am attaching pictures.

Please help

Give us a little more info. What type pool is it? How do you chlorinate? Etc?
Also, Post a set of test results and how you got them.
What do the stains look like? (Raised, level, hard, smooth, etc.)

That's Calcium scale. You're not alone. There are more pictures, including some of mine, here: help-with-two-different-plaster-issues-stains-t36205.html

I keep my pH below 7.6 all the time, and TA about 50-60, which with my CH, keeps the Calcium Saturation Index in the negatives. I've dissolved most of the scale from the spa and the steps so far, as they're easiest to brush. The rest is about 50% gone. Another year and it should be clear.

Unless it's rough and scrapes skin off, it's just unsightly. If you want to be rid of it fast, hire a pool company to drain the pool then acid wash or sandblast.
