well here is the tank in question. as you can see the tank dose not look great with nothing on the bottom lol. the bubbles are the Co2 as there coming from the deffuser and into the powerhead. the large mangrove wood came from germany as it was cheaper than buying local ( lfs's were wanting Â£100+ ) where as it was only Â£30 by the time i paid for shipping. am thinking in moving the taller plants to behind the root in the right corner to make way for slightly shorter planting / bushy planting in the left corner. sorry for the pretty poor pic . i only just took a quick shot of the tank. it is a little bit brighter than what it looks in the pic.
