Hiya, I've been lurking on this forum for a year or so and it's provided me with some good information, but now I need more specific help.

The background: I bought this house with the pool a year ago. When we first viewed the house the pool was about 2/3rds empty and it looked like a swamp. By the time we moved in they had cleaned the pool up and the water was running clear. None of the pool equipment has any labels, but I've managed to figure most of it out while fixing stuff or asking my local pool supplier. Don't really know the gallons on the pool: it was a diving pool but the board was busted so I took it out.

Now my problems: the finish on the pool has some cracks, but I'm not even sure what the finish is let alone how to repair it. The other problem is black stains on the pool bottom: are they algae or something else?

I still have to figure out how to post pics, because I'm sure they would actually help out some.

Anyway, thanks a bunch.
