You have inspired me. i mean i work next to a glass shop who throws out huge sheets of glass everyday haha.
your tank is absolutely stunning. two thumbs up.
one thing about your lotus. I threw some lotus bulbs in my tank many years ago and it thrived. took over the whole top of the tank and i loved the vines saggin down from the top of the tank to it's base. it was sweet watching all my fish swim threw it... but then it just took over. all my other plants started to die off. my tank was is a standard 55 with about 3-4" of black flourite. after closer inspection and a trimming i found that the lotus roots had spread out through out the sand of the entire tank stripping all the nutrients from my over plant. Also the floating pads when they get larger block a lot of the light from your shorter plants.
I'd think about pulling the lotus just my opinion. If you have any suggestions as to what i could have done to prevent the problems I had I'd love to hear.
and once again man I love your tank. one of the best i've seen
