Algae On Leaves

[monkey_wrench]

Hi..

I have algae and this weird fungusy substance that looks like dust growing on the leaves on my plants..and i cant get rid of it!

Ive added another powerhead to increase the flow in the tank, ive reduced the light, ive reduced the amount of food i give the
fish, ive been doing 15 percent water changes every second day but it still wont go away!

Water stats are
Ammonia-0
Nitrite- 0
Nitrate- 20
pH 6.6

I've been using the yeast method c02 injection but have saved up for a pressurised cylinder for more control and will be switching to that very soon..

Do you think its the c02 injection method causing the algae?..the tank is 75 gal

thanks

Adding co2 into the tank doesn't cause algae.

What ferts are you dosing and how often/much?

what i meant to say with the CO2 is whether uncontrolled and uneven injection could cause algae

i use seachem iron and potassium

i keep the iron at around 0.5ppm and potassium about 20
