My pool has been running for about 6 weeks now and I have begun to get some major calcium build up near the spill over. We have hard water in the area and my CH is about 300. What can I do to prevent? I hit it with acid about 7 days ago and its came back.http://lh4.ggpht.com/_en6EMqEt-eQ/S-...8/IMG_0133.JPG
I have provided a link to the picasa image of the build up.
Thanks in advance
