I do have a non-controversial question, though.

In order to keep most aquatic plants healthy and growing, it seems that
the minimum lux level is about 1800. Is that correct?

What is the minimum PAR level? About 40?

I've a 150L planted tank with a single 10W household halogen bulb on it?
Does that count as low? :-)
