buying a house with a pool

[Shannon]

We're in the process of buying a house with a very large in-ground pool. The water is black but no odor. It does have a DE filter and we're wondering which is the best way to clean it. Should we run the filter, backwash, filter again or should we just drain it and start from scratch? We're not sure if there is any damage. The area around the pump is boggy but the gutter down spout is located next to it and it has been raining off and on for several weeks. Also the pump is busted so there could be the possibility of water backing up and spilling there. DH thinks this is a gunite pool. If it does help...in a shallow area of the pool that is exposed (makeshift cover over pool) the bottom can be seen but it is faint. Thx for any help.

Dear Shannon

I suggest that you drain the pool so that you can really get a good picture of the state of the surface itself. You may find problems of cracks, stains or surface wear which may need attending to. It will also be a great opportunity to get your pump fixed and check the pipes for leaks as the

area around the pump is boggy

You may think about an acid wash once you empty the pool, especially if it is a gunite pool. That way you will start with a well-functioning pool with minor or no problems.

Good luck
