We typically do not suggest totally draining a pool. Also, acid washing is a last resort because it removes a layer of your finish and makes a pool more likely to stain.

Qwaxalot, we appreciate that you have tried to help a few people, but since you are a brand-new trial member who just joined today and whose registration has not yet been completed, I'm going to ask you to slow down a bit. Do a lot of reading on the forum (until your registration is complete, you'll need to log out first to be able to see the rest of the forum) and also do a lot of reading at our sister website www.poolsolutions.com. That will give you a good feel for what we are all about. For now, just read and enjoy. Thank you!
