Went to a few LFS to shop for the lights, finally I've got what I wanted, it is a the Aqua Zonic Super Bright double tube 24W T5 lamp with 12000K brightness, and it cost around RM160(50USD).
Put up the light to test for the brightness. It is really a good workmanship, and I am highly recommended this light for a small tank.
This is nightmare, went back to my old house to collect all those full of algae driftwoods, the time I spent on washing it, was really killing my back. Tried to arrange it on the floor before put in the tank.
Still not the final arrangement, need some fine tuning. Meanwhile added some water to 1/3 of the tank.
