So I am just getting started in pool ownership, and have my water crystal clear, test results are good, everything seems to be going well. Then this afternoon I noticed what looked like black marks in my waterline tile grout, but after a closer look there are hundreds of little black bugs that look exactly like fleas? I brushed the tile, and they just kind of hop across the top of the water and then go right back to the waterline tile. Anyone ever heard of something like this? I did a search but don't see anything? Would appreciate any insights...
Thanks,
Mike
