GH of 103ppm is very soft, no problem for plants or soft water fish species. With a pH of 6.5, we can assume the KH is going to be similar to the GH. All that bodes well.
I had Flourite several years ago and found it more trouble than benefit. After two years it got dumpd in a hole in the back garden. My cories within a week of setting up the Flourite tank had to be removed due to very serious barbel erosion, but they recovered over soft sand. This will limit you fish options, which may not matter if you do not intend substrate fish, but cories and all loaches should not be housed over this or any similar "plant" substrate. There are issues of sharpness but even more risky the bacterial problems.
