getting rid of the green

[schizo_fish]

I have a serious algae problem, by that i mean my water is green.
I've heard that an increased level of CO2 will help plants grow, so if i was to adjust my internal fiter so there was less/no surface movement in theory this would make the level of co2 rise. is this correct?
Would doing this enable my plants to out compete the algae?

any help or advice would be great.

If this is a new tank then an algae bloom is normal and will dissipate when cycling is complete.

Surface agitation adds dissolved oxygen to the water, so helping fishies respiration, but doing the opposite for plants (CO2 goes out of the water). Many planted tank keepers get thier tanks upto full oxygen content (water can only hold so much oxygen), this produces 'perling' where the extra oxygen is produced as bubbles from the leaves.

I know nothing about growing plants, my plants either take over my tank or rot to nothing try posting in the planted tanks forum.

You want NO CO2 if you dont want plant growth - factors controlling growth of plants are:

Temp
nutrients
water
amount of gas (CO2)
light

probably more but too late to remember, your best bet is drastically reducing the amount of light in the tank - maybe covering it with a blanket in the day?
