Uncovered pool April 1, 2017. What a mess! Lots of decomposed leaves and muck but I anticipated as much from Hurricane Matthew. Had to pressure wash both sides of the solar blanket to knock the grunge off as bleach and a ordinary garden hose were ineffective. Plastic tube from skimmer to outlet rotted brittle. Leaf picker upper (with garden hose to produce suction) was my first go. The mesh bag caught some slime and muck, but mostly I just stirred the water into an opaque brown. When vacuuming blindly, the brown particles were so fine they went right through sand filter and came back out into the pool. Nasty! Been backwashing every day and each day the water is noticeably clearer. Had to add CYA today. pH is low and I forgot to buy Borax today. Keeping FC around 7 until such time as I get the opportunity to vacuum pool properly now that I can see the bottom again,. Temperature is in the low 70's so I'm not too thrilled to be getting in it to vacuum. Yee haw, ain't life grand!
