I have had some brown dust algae which I easily brush off and keep on top of, but all of a sudden on a piece of slate I have a purple hairy algae spot about the size of a ten pence piece. I have never seen this colour before in a freshwater? Does anyone have any advice on this?

try googling 'black brush algae' and look under images does it look like that? i have trouble with this and under some aquarium lights mine has a purpleish tinge to it
Well I think it must be that stuff. Could you please tell me your experience with this stuff, do I need to worry about it?

basically ive been trying to battle it in 2 tanks, my 2m community tank and a smaller 1m community. in both ive been totally unsucessful in getting rid of it so gave up and learned to live with it! so if anyone can come up with anymore suggestions on how to get rid of it, id gladly try it!
Its not the worst looking algae Ive ever seen. Is it likely though to go everywhere or stay in small clumps?

Often grows on leaf edges of slow growing plants, bog wood and mechanical equipment. Also sometimes it grows in fast flowing areas of the tank. Grows in clumps or patches of fine black tufts up to about 0.5cm long.
Cause In a high light tank it is an indication of low or fluctuating CO2 levels or not enough water circulation around the plants. In a low light tank it is often due to changing CO2 levels.
Removal In a high light tank you will need to increase your levels of CO2 and/or improve water circulation around the plants. Scrub and cut off as much as you can first. Increase levels slowly to 30ppm or more but watch the fish to see if they are respiring heavily. Make sure you have good water flow around the whole tank along with some good surface movement. Adding a powerhead may help.
If you have a low light tank without CO2 injection then not doing any water changes will help. This is because tap water often has lots of CO2 dissolved in it which causes CO2 levels in your tank to fluctuate. The algae respond to this a lot quicker than the plants do.
Siamese Algae Eaters are known to eat BBA so can be used to control this algae.
Overdosing Flourish Excel will clear it up.

Ive absolutely no idea 
I gave up on a planted tank a few months back as I couldnt get my co2 levels up enough without pressurized system.
Try asking in the planted forum or PM aaronnorth
To be honest, if it was me, Id use the excel overdose method as suggested in the text.

Mine looks quite nice at the mo too!
Im preparing myself though in case there is an outbreak!

If you don't have sensitive plants it's no worry, just grows on the surfaces exposed to light. If you leave it be it eventually carpets.
In planted tanks it can be a nuisance as it can kill plants if left unchecked.

scrub it off & do a 80% water change to remove the algae spores.
