That is an interesting thread. It looks like most of the reasons for choosing eco were colour and ease. The most common cons were compaction and leeching. Im gonna look for one of these about fluorite.
As for the wpg thing I guess when I start to specifically choose plants i am unsure about I will post here and see what people say.
I will be dosing excel here and there I wont be dependant on it. Also I will not have C02 in my tank. (just for more info

)
I was staring at my empty tank earlier and I was really afraid of the exposed lights being so close to the top of what will be the water surface. The only thing protecting the wires are endcaps. Hagen waterhome manual says its fine but it really freaks me out. What about splash or condensation? Its a fully sealed top so it worries me.
The lights were about 1.5 -2 inches from the top of the water surface. So I took the frame for the bottom of the tank (its an optional item with this tank so you can make it rimless) and I put it on the top to make a frame around the top of the tank (acting as a riser) and then I put the hood on top of that. The lights are now about 3-4 ? inches away from the waters surface but it still freaks me out.
Any ideas on what i should do about this? I dont want to have to go out and buy a whole new lighting set up. I mentioned it to my husband once and it hurt him because he thought the gift he gave me wasent good enough. It took me all day to fix that problem.
So any ideas?
