Hello, in a 20g tank witha nasty bacterial bloom, I'd like to get
some anacharis in there. I like live plants, and I don't
have a very bright lighting system. The problem is, currently
the lights are on for about 2 or 3 hours, due to the bacterial bloom.
So, I wanted to know how kcuh higher I would need to knock up the time
the lights are so the anacharis will live. I however do not want the
anacharis turing into a weed, as I have heard they can with too much
lighting. Thanks in advance for help.

Unless it's cyanobacteria, I don't believe the light will encourage
non-photosynthetic bacteria to grow. Maybe you mean algae bloom?

How many watts of lighting have you got there?

If it's a low lighting, non-CO2 injected tank, you'll need, I reckon, at
least 8-10 hours. Maybe other have grown it in less?

I don't believe there's any chance of it turning into a weed, unless
it's given the right conditions. Actually, turning into a "weed" may not
be a bad thing either, if you're NOT trying. It means there's copious
nutrients in the tank water, something you want to get rid of anyway.
It's easier to grab a few plants to chuck out than change buckets full
of water.

I've used anacharis in plated tanks and as an 'excess nutrient sponge'
in others. one tank had the lights on whenever I remembered. If there
is any indirect light, it shouldn't take much of the tank light per
day. The biggest difference I have noticed with different lighting
conditions is the awy in which it grows. (low light it grows long with
not much leaf, high light, darker green and bushier leaves)
