So, I have cleaned the pool, and filled it up. The water just reached skimmer level, just a few more inches!! I have read through pool school and done a few of the suggestions. Pics and 1st "leslie's" test results in my intro thread. I just bought some DE for my freshly cleaned out FNS Plus 60 filter. During cleaning, I noticed that I will soon be replacing the grids as there are some broken and brittle pieces. However, I am extremely pressed budget wise until payday. I also have to raise the calcium hardness level in the pool. I will be ordering a test kit for my own testing in the next week or two. But main question for today is do I continue adding the hardness adjuster while adding the DE slurry for the filter? Should I wait til i have new grids before using the DE? So many questions and little things that need to be addressed that I am glad I found this forum. I'll be my own pool guy from now on.
