Subject: Thoughts on Compact Fluorescent Lights
I have swords, anubias & java fern in a 20 gallon long tank, growing under a
20 w daylight bulb with no CO2. All seem to be doing very well. The tank is
near a window, but doesn't get direct sun, but for a few isolated spots for a
few minutes, late in the day. There is also a water sprite in there growing
like crazy. It depends on whether you have a 38 long or deep tank, though
I've even seen anubias and java fern in a 20 deep under a regular 20 watt
cool white. Those plants will do well in low light. An attempt at keeping a
sword in that deep tank did not work.
In my limited experience, some fish species are not happy in bright light.
Since I'm going for a balance of fish and plants (not trying to grow a
jungle) the light I have is a good compromise for fish and plants, and all
If you have a long tank, see what happens with your single strip, but get a
good bulb. The difference in light output between cool light and daylight
bulb (not a plant bulb) is like night and day. Plant the swords, which
require more light than the others, directly under the light. If you have a
deep tank, a double light strip would suffice, I would think. This pertains
to the plants you mentioned.
