What is your FC level? If you are not keeping it at 15ppm round the clock you won't get rid of the algae.
I frequently get light algae on some of the walls and nooks and crannies when I neglect the pool for any period of time. Brushing those areas is tough. I rig the vacuum hose and brush to one of the return jets so it blows. Makes it easy knock stuff loose. Typical return jets are 1.5" threads so just get a 1.5 inch male PVC pipe adapter and cement a short piece of 1.5" pipe in it. The vacuum hose end that hooks to the skimmer will fit inside the pipe. Also get 1.5 inch threaded pipe plugs for the extra return jets. Take out the eyeball, screw this thing in and go. Once the algae is in suspension the chlorine can do its job easier. Never had to deal with black algae but this may help.

my fc level has to be high not sure exactly how high though
when I test my chlorine I only have a leslie cheap o test kit but it turns dark orange so I'm guessing at least 15 ppm. The black algea is gone it's just the roots that I cant get inbedded in the concrete.
I'm getting a barrel of 15% sodium hypo wednesday from a friend at a plant near my house, that they use for treating drinking water. I'll try again next weekend.
Chlorox is getting high around here it's 4.30 for a 196oz of ultra at home depot and lowes and about 20 cents cheaper at walmart. I found some 3% value time bleach at local market for 1.50 for the 1.96 oz.
I think I dumped 18 196oz bottles of chlorox ultra and three one pound packs of hth super shock in my pool from friday to sunday it made a expensive weekend.
Wow...$4.30? Last I bought at the Malwart around here was $2.54 for 174 Oz, 6%. That's in Northeast PA.

Be careful! The Chlorox sold at my local Home Depot isn't appropriate for pool use as it has other ingredients besides simply Sodium Hypo and salt-water. I NEVER buy it there for that reason.

This is the bleach homedepot sells
walmart only sells regular chlorox thats almost the same price.
Hi Kingcoota;
I read a lot, and there are a lot of phrases and expressions I like. I encountered one today that's not new, but I don't recall having had a chance to use it . . . but you've provided me with one, so I'm excited.
I checked the link you posted (I do the moderation on all the links, attachments, etc, so if you want a post to get modded quickly, don't put a link, etc. in it!) to Clorox Professional. What I noticed immediately is that the distinction between Clorox and Clorox Professional is a distinction without a difference. (that's the phrase I wanted to use - thx!)
Both are 6% chlorine (wt / vol %). In other words, the only difference is the label, and possibly, the price.
With respect to consumer and small business chemicals, it's the same ol' same ol' -- chemical companies have a relatively small number of useful products and most of them aren't new. So, to create market buzz, they dream up new blends, new labels, and new ways to put an exclamation point in text. And then, they use all this to sell the same old products they always have.

I thought they had stuck something in the C-Pro that wasn't pool friendly. I'll have to look next time I'm at the Depot. Didn't Chlorox brand just add another ingredient to their bleach that nobody's certain of whether it's OK in pools or not?
Just a little lie.Quote:

All bleach has a slight excess of sodium hydroxide. It's made by bubbling chlorine gas into concentrated sodium hydroxide. Bad things happen if the sodium hydroxide get used up while the gas is bubbling.
