You are welcome, and thank you for filling out the requested info in our pool chart. That will help us better help you. In that chart, I noticed that you said that you would be using both city and well water. Do you know if your well has metals in it? Metal contaminated wells are a HUGE source of problems for many pool owners. Take a few minutes and read through some of the posts and stickies in the minerals section of the forum. Until your registration is complete, you'll need to log out to be able to do so. Any chance that you can just use your municipal water and not the well water?
