I'm new to the forum, thanks for advice in advance.
I have a retaining wall on one side of the pool. It has a flagstone face and I'm getting a little weaping of moisture and a build up of limescale or whatever the white mineral build up is. I've attached a picture to show the problem. Any ideas on how to address this? I've tried pool store scale removers, CLR and diluted MA with no luck. I literally have to scrape the rock like build up with a scraper and then use a pumice stone on the tiles. Just not sure what to use on the flagstone.WP_20140720_001.jpg
