Another Aquascaping competition, here the detail from the website: 
Second version with floatable head
OK, sketch is easy, make it real is hard.Some issue that I can think of:
1. Need a transparent tube which does not turn cloudy after long period in the water. Non tranparent will defeat the purpose of using lily pipe.
2. Secondly need to source for plastic screw, metal screw will scratch the lily pipe glass. Also need a way to create screw thread on the pipe. This screw will be used to secure the surface skimmer to the lily pipe. Need at least three.
3. Need some material for the bottom, the part that blocking partial of the inlet.
I just bought Boyu inline CO2 diffuser. It can be use inside and outside tank. Just take out the strainer if you want to use it outside the tank. I heard it is very efficient and maintenance free. Not sure how true it is. My guess is brown algae probably will grow inside after a while. 
I am having trouble creating large size lake just like in the photo without making it too boring. In the photo the water in the lake create ripple and reflection which make it interesting. No way to re create that with white sand. Large empty area with same material or plants always make it boring. I need to find the way to break it. Searching for alternative way, I found fantastic photo of Toad River from National Geographic. So I change the lake into small river with many branch and twist. It wasnt a great scape but at least it shouldnt be too boring.
O... by the way this tank was suppose to be experimental tank. Many people (I was one of them) believe that flame moss need cold water (around 25 degree C) to have nice flaming effect. But I was wrong this tank water temperature was hover around 28-30 degree C with the help of 24hrs fan and yet the moss give nice flame effect. On hot day, it can even go up to 32 degree C. Also if you are notice, I use only 36W PL to grow HC on 2ft or ~20 gallon tank. Again many people was think that HC require very high light but not necesary the case.
The only different is moss grow in high water temperature look skinnier as seen in 100% crop below. The moss on top is flame moss and the moss below is spiky moss. See how skinny the spiky moss is compare to the same moss on my other chilled tank.
Plants list:
1. Hemianthus callitrichoides
2. Taxiphyllum sp. (Flame moss)
3. Taxiphyllum sp. (Spiky moss)
Some photos showing where the idea come from. Photos was taken from the internet, not mine. So if you are the owner, please let me know and I will take it down.
