hi queen angel. welcome to the forums. :bounce:
I too like fluvals and eheims as you don't have to muck around with them at all. plus many are willing to pay more for convenience.
ok so with this tank you'd like to plant out -
what sort of lighting does the tank have (what K tubes, usually a number like 6500K, 10000K, 18000K etc)?
JBL aquabasis is a good plant substrate, but if you choose to go for undergravel heating (they are usually 5-15W so you will probably not notice a difference in power consumption) you make a zig zag pattern going from the front of the tank to the back, working across the tank. then you put the substrate on top, and strategically place a few plants in such a way that they can grow out once the roots establish.
as suggested earlier, only use liquid plant supplements like PMDD and flourish etc once the plants show a little growth.
since you are wanting JBL substrate, you may as well go down the DIY CO2 route and make your plants even happier. for cycling the tank, I would recommend zebra danios as they are hardy and look really nice in a group and are always active.
HTH. ask away of you have any q's :bounce:
