Great to have found this site. I just had my pool resurfaced in January and used diamond brite. I have been very happy thus far, but am noticing what seems to be a lot of loose particles/ sediment that at first glance, one would think is sand. However, upon closer inspection, the particles are the diamond brite. My initial assumption was that this was just part of the process of a new pool and that the accumulation of the diamond brite would eventually stop or slow down. However, I keep finding it and am now starting to get concerned that there was possibly a mistake made in the installation. Is this normal for the first couple of months to lose a bit of the material or should I be waving a red flag? Thank you.
