I'll comment on one of Peter's lighting questions: >>>5. I need 3
watts per gallon for a plant tank = 375 watts at least.>>>
With compact fluorescent lighting (CF) my rule of thumb is to reduce the
watts per gallon rule of thumb a bit. I think you can find some info in
the Krib and APD archives on this, but I think CFs produce more light
per watt than regular fluorescent lighting and if memory serves, also
more light per watt than the new energy efficient T-8s. 3 watts per
gallon CF lighting drove my tank into a frenzy of growth and more algae
production than I would otherwise have. My non-scientific observation
is that very bright light seems to differentially benefit algae more
than higher order plants. By stepping the CF lighting back a bit, I can
still have great plant growth and less algae.
2 watts CF lighting per gallon should be plenty of light.
