I had a TIME with it last year and never could get rid of it. I ended up just shocking like crazy, adding algaecide and putting the cover on. Surprisingly when I opened the pool this year, no algae. I fully expected a mess.
First few weeks all was well.
Not so, now. I just walked out to check things today and noticed on the shady side of the pool, yellow again on the bottom in streaks like last year. Hubby got in and said it felt slimy. Great. It looks exactly like it did last year. I HATE this stuff. It was such a pain.
Here are my numbers
CYA Less than 20 still
What should I do? Shock like crazy for 3 days? Put in algaecide of some sort? I do NOT want to have to fight this again for weeks this summer like last year. And I never did get rid of it last year....just gave up.
