algae

[hannadock]

I opened up my pool memorial day weekend and finally got a clear pool a week later, BUT yesterday I noticed some algae starting to form on the wall. I brushed and vaccum on waste. It has been in the 90's here for a week and a half. My numbers are within spec based on this website recommendations.

How long should I run my pump?
How often vaccum the pool?
How long should I run my kreepy krawly?, I don't use it much at all.
Do you chlorine tablets hurt? I bought some on sale last year at a good price at Lowes.
I have a inground vinyl pool 20 X 40 around 36000 gal.
I had the same problem last year with the algae and my numbers were always in range.
Sorry for all the questions
