Would anyone be able to respond to this post? The algae is getting
really bad and taking over a lot of my plants despite my best efforts
to remove it physically.

I've read that doubling the dose of Seachem's Flourish Excel for a few
days will get rid of it. I've seen success with that in my little 2.5G
betta tank (the algae turned orange and appears to be dying off) but
with my 180G tank which is pretty heavily planted, I'm having a hard
time figuring out how much to put in, especially since I already inject
C02.

Any advice from the group would be greatly appreciated.
