lighting for water lettuce?

[c_scherer123]

I am wondering what kind of light water lettuce/hyacinth will grow best under? They need fairly intense light.
I have read 6700k is a good go, is this true or does it need more?
What spectrum does it prefer?

I am thinking of this light: Hagen Glo T5 High Output 24" Single Light Fixture - With Life Glo II 24Watt T5 High Output Bulb

Would this work?


Tank: ~10-12g with 24" light connected to heavily stocked goldfish tank (all the nitrates the plants could desire...)
Will have mirrors on back and on one side (one site said that this really helped...)
Plants I want: water lettuce/hyacinth, northern milfoil, parrots feather.

that should work. mirrors wont help much. how many gold fish do you have in there?

This little tank will be connected to my 65g that overwinters a number of my pond goldfish (14 4" common/comet, 3 3" fantails). Overstocked, but they spend the summer in the 300g pond and more return to the LFS every fall.
There won't actually be any goldfish in the planted tank, a few mountain cloud minnows to eat any bugs, but that's it.
