1) Drain water
2) Wash sand (hope it's enough)
3) Add RO water
4) Start adding salt
5) Check water and wonder why the salinity is sooooo high??? (Did they give me mixed water at the store? -I need to get my RO/DI unit set up.)
6) Water looks better, now we'll see how it does in the morning.
7) 9pm and I'm heading home...
