Okay, good sign!
Brush, brush, brush, (everywhere), and keep your FC on the higher side. You might have caught it in time.... Let's hope!
If I can't get in the pool, I always at least reach in and feel my sides. When I do get in, I always feel the floor, corners, and less well-circulated areas carefully. I have not had a "slimy feel" in eons, but I always check.
Keep a careful eye on CC and FC loss just in case!
