Greetings fellow chlorinators,
Being fairly new to the pool maintenance adventure and having inherited a sorely neglected pool I am getting a crash course, with the help of you all and Pool School, in many aspects of pool care and problem solving. I have had, so far, three algae blooms. All three instances undoubtedly due to my ignorance of proper chlorination.
The formerly neglected pool is tiled with 1"x1" white tiles and in many areas the grout is dark looking. In a large circular area around the main drain the grout is white. (You can see the transition in the first pic.) I have been brushing the whole floor daily at least once and sometimes twice for weeks now with no improvement.

Overall the appearance is blotchy and not particularly attractive. To make matters worse I have a daily precipitation of gray/green sediment which makes the darkish areas look black and furry. So I'm guessing (as always) that either the pool filter is recirculating the sediment or I have an ongoing growth creating it on a daily basis.
Since the blooms I am keeping the FC above 5 at all times. That is based on my former CYA level of 60 which is no longer valid as it has fallen for some reason but my fear of algae has made me paranoid.
I'm thinking I need a better brush. Is it Ok to use a partial SS brush on tile?
