Thanks everyone for your input it has all been helpful. I have decided (but will probally change my mind) on going for a mixed blend of Eco-complete , regular gravel and river sand for my substrate with a few dino dung pellets strategically placed. I am unsure with the lighting I have found some halide/t5 combos here They have a top function in that you can use just the halide or the t5 or both . I understand that my tanks might be to deep for HC or glosso but i did intend to have one side banked/raised high a the back slowly sloping down to the front of the tank with that side having the ground cover other plants I am keen on Java fern "windelov" , downii , Rotala red, Pogo stellata a moss of some sort (all so similar) and assorted swords and crypts would the combo lights suit???/
Got abit of a laugh on ebay searched "dino dung" and up come all these fossilized dino doo's for sale.
