My New 36X18X36 ExoTerra Build. A Video and a pic of an issue I am having....

[Bnagy]

Hey guys. I finished this build about 3 weeks ago. What a long and drawn out project! It came out nice, but I am having a few issues. I have an egg crate bottom with water underneath that is filtered and pumped up to the waterfall by a Fluval 105 with charcoal, sponge, and filter floss media. I had to use a ball valve to slow down the water fall, but I still getting some splashing here and there that is soaking the substrate. The substrate being wet caused me to have gnats that grow I the soil. I need to figure out a way to get rid of the splashing. Is there a solution or the gnats?

I also have this clear slime growing in the water below the egg crate and I cant figure out a way to get rid of it and keep it away. Anyone know what it is? Maybe algae?

They seem to like their new home. The plants seem ok other than the two bromeliads, they are dying. Can someone recommend 2 replacement plants that will look as good and live?
