"Not enough light for healthy plants = algae.

Too much light and not enough CO2 for healthy plants = algae.

Too much CO2 and not enough light = dead fish and algae.

Wrong temperature = algae.

Improper any of the aforementioned for plants to utilize the available
macro nutrients = algae."

May I suggest the positive converse: keep your lighting low, grow
plants like Anubias, then you can have healthy fish and healthy
plants without worrying about CO2, fertilizers, temperature OR
algae!

I just responded with the light level question in mind, Koi has about
a 3watt/gallon light level. I don't recall any discussion of too much
light and the effects. Koi is using low light plants.

=====================
But that doesn't stop this "black" algae. Those were the conditions that
got me started on better lighting and fertilizers last winter. That's why I
upped the gravel vacuuming, added another fluorescent fixture to the tanks
and bought all the expensive Flourish products. The only difference is my
wallet is lighter and instead of the black sooty looking algae I have a
black wiry algae.
