Is eclipse system good for freshwater plants?

i have an eclipse 6 planted tank. the light it comes with is just right. As for substrate you will want to avoid sand as sand is mostly silica and you will see no end of brown algae (diatoms) Flourite tm or black sand for planted aqariums is the best substrate, it has food for the plants mixed in, and it is a good texture for the roots to sink into. Pick up a good fertilizer for aquariums, flourish products work great however they are packaged to dose 10 gallon tanks. I usually just halve the dose. Start with plants first. Place the substrate on the bottom of the tank half fill the tank with water then place your plants and decor as you like it, run the tank for a day just to make sure all of your equipment is in working order, then add a fish or two, avoid destructive fish like silver dollars, gourami, barbs, goldfish, or cichlids (although most of those shouldn't be an issue with such a small tank) I have a male betta & a school of neon tetras in my eclipse 6 planted tank. My tank was cycled with a small school of zebra danio that are now keeping my hospital/ quarrantine tank cycled. good luck!
