I am currently in the 4 month of having my planted tank. During the time it
has gone through many changes. In the last month I have stopped supplying
my tank with CO2 via DIY yeast bottles. During the time that i was
injecting the growth of the plants were tremendous and the algae was few.
Now that i have stopped co2 dosing (ran out of sugar and ordered a
pressurised system) my tank seems to have grown a fair amount of algae. No
matter how much i scrape or how much my algae crew eats it still returns. I
was wondering does the amount of co2 in the water have something to do with
algae control. My setup currently is a 55 gallon acrylic tank with 4 - 45w
flouresenct strips as light. Is this to much light or will it be fine?
When i start boosting co2 again will the algae problem resolve itsself or
will it increase? Should i continue to fertilize (currently use plant zone
liquid fertilizer). Any help I can get would be deeply appreciated. Thank
You.

B, adding CO2 is the single best thing you can do even at low light.
I've found this to quite true independently of this article a number
of years ago.
Plants are 40% Carbon by weight. Algae have very small carbon needs
and all algae are well equipped to use HCO3 rather than CO2.
KIf the plants stop growing or are not growing, algae will. So grow
the plants well and you'll have no algae.

This is a very good article:
