Algae on glass

Okay I want to know whats the best way to keep algae of the front glass of my 60 gal african cichlid tank?
It usually grows really quickly maybe 2or 3 days after I have cleaned it off with a sponge...I tried reducing the duration of the light to about 9-10 hours I try not to reduce it too much because I have some plants in the tank...I also tried reducing the amount that I feed the cichlids...I have even done large water changes...the last resort thing that I tried was adding Tetra Algae Control I Know I know what everone is going to say that I shouldnt add chemicals, but I did so get over it...I was desperate...because I had all types of algae growing everywhere it actually helped quite a bit....but the algae on the glass still grows quite rapidly...so if anyone has any suggestions...maybe a pleco or other algae eaters...or something else (phosphate remover).....

Its green...now that i look at it, it kind of looks like really small hairs

It comes back with in a couple of day I wish it was with in a month...no it actually causes algae as does silicates

how will the co2 help with the algae...i know it will help the plants

Blue-Green, also known as Slime or Smear algae – Caused by excesses of nitrates and phosphates, this is actually not an algae at all. Instead it is a cyanobacteria. It can spread rapidly, and can cause considerable damage. Good water care will help, but if your water source has phosphates in it, you may have to use special treatments to remove the excess nutrients. Erythromycin is also effective against Blue-Green algae.

Phosphate is utilised by all plants and consumed quickly by algae.

I was saying in general that most algae use the phosphate as a nutrient...but it is kind of like the spot algae but the spots are alot smaller and the kind of look like like hairs i think it maybe fuzz algae like this one on this website
