What is your experience with fertilizers and CO2? I am currently
experiencing algae on the glass of my tank and leaves.
I think is because water my dosing of fertilizers and CO2 is not the
correct, it is over what it should be. I use liquid CO2 and Tropical
Master GRow.

I can grow algae in an unfertilized tank. I've got one tank that if I don't
watch it like a hawk it will sprout every kind of algae known to man. High
nitrate, low nitrate, high PO4 low PO4 plus a few other variations all can
cause algae it the rest of the nutrients aren't right for health vigorous
growth. When I get lazy and let things get out of whack.... Actually I
never had such problems with the tank under low light conditions.

Since I'm lazy, I use the Tom Barr Estimation method with big water changes.

My tank is a 58G tank that has vals, differen types of swords, dwarf sag,
red ludwiga, and some other plants I can't remember there name. The light
is on for around 10-12 hrs a day.
What doses do you recommend? What can I do to save my plants and get rid
of the alage?

As for getting rid of the algae .... probably increase your nitrates and
phosphates.
