My 2 cents...
My tanks are usually low light, (only ambient/indirect sunlight, or <
I find a correlation of fertilizing to algae breakout (R=0.91772) when I
as instructed by the manufacturer (Dupla, Tetra, etc.).
I'm certain it's a balance issue, and low light tanks simply aren't as
(able to capitalize on available nutrients as effectively). I find algae is
poor competitor when the plants have good circulation and are somewhat
healthy. However, in my case, the algae seems to be picking up the slack
when I add fertilizer (big nutrient spike in short time, my plants don't
that fast). Maybe I just have lazy plants. Maybe they are watching me, and
I'm a bad role model. I'll keep a lookout for a motivated plant that can
a better example.
I haven't noticed a toxicity issue, but I admit I haven't been checking and
my loads are usually low. However, the more toxic nitrogen forms (like
ammonia) are typically those most easily taken up by plants. So, if you
have at least a couple successful plant species in there, I'd guess it isn't
too big an issue.
I'm assuming this would not be as big an issue if I convince my wife we
need MH lighting. ;-))
Green water, thread algae, little spots, etc. I can presently make any kind
of algae I want. ;-))
