my pointers would be, use good ferts= tropica plant nutrition+ and easylife easy carbo(carbon supplement)
have pressurized c02, depending on light levels, ie. low light levels no need, just use easy carbo
tropica planting substrate, capped with argos play sand
get plants like anubias, crypts, mosses, ferns, amazon swords.- easy plants, quite slow growing.- means easier to maintain
when you get plants remove old and damaged leaves and cut off most of the roots to give the plants a kick start
plant "dry" ie. no water, use tweezers and push plants into substrate- then fill carefully
use good quality plants, aqua essentials do tropica and aquafleur, generally the more expensive the better, however some aquafleur plants(cheeper than tropica) are better than tropica.
any other questions ask
