This will be my first year following the BBB method entirely. Trial was end of last year as I wasn't willing to empty my pool to the level it was needed in order to get my CYA down. I had a professional close my pool really late. It was crystal clear when we closed and he threw in a 3 month algaecide. I just pulled back the cover and it is very green (already??). We just had our first over 40 degree night temp. I'd like to open the pool myself this year so my question (after reading the sticky on opening) goes as follows: I assume I should apply a 3 month algaecide again and raise chlorine for good shock to get started? When sucking out what is on the bottom (I have a tight mesh cover but worms and leaves/dirt always make it in), I should be vacuuming to waste, I assume? Is anyone aware of a tape that provides traction for safety that can be under water all season (my stepmom broke her arm last year slipping on my steps)? I drained 1/4 of my pool to close last year (which is what I needed to get my CYA down according to calculations) but it filled back up over winter. Do I start by shocking and algaecide first, then testing for CYA, then removing water as necessary or some other sequence of events? Thanks for the help--this site has been a godsend over the last 3 years. . .
