Yes, it's not crystal clear for sure! Blue but cloudy and I"m still trying to vac up all the dirt and sawdust from over winter. I've vac'ed 3-4 times now but it's sure taking awhile to get everything out. My vac seems to just push a lot of it around and it gets suspended until it settles and I vac again.
My bleach I do add seems to be holding pretty good except for sun loss but the water isn't clear after I vac. I just need to slam.
I'm also thinking about borating this year.....
