Hey guys...I have been looking at waterfalls online...and really think they are crazy too expensive...so i googled "how to make a waterfall" and came across this killer site...this guy shows how to build a huge waterfall for a 75 gallon tank...my tank isn't that big, but it gave me a good idea on how to build one...
Here is the link:
How to build a waterfall for a terrarium
I made a few adjustments to my waterfall...I decided that i wasn't going to take the 'great stuff' route because me and that stuff do not get along...instead I am going to use grout...I have built a background before using grout and am comfortable using it...I just have one or two questions before i get to the grout stage...Should i use an aquarium silicone before i grout or will i be fine? The other question I have is, after i grout it a few times and seal the grout with a sealer, how do i make sure it is safe? Don't I have to submerge it in water a few times to make sure the ph level is correct? Here is what I have done so far...

This is the base...or where the pool of water is going to be...

This is where the water will come out of the pump to and fall down to the pool...

This is the top...it is going to hide where the pump is pumping water to...And yes that is blood...i cut myself being careless while i was carving the rocks...Damn that sharp knife...lol...

And this is what it looks like all together...
If anyone has any suggestions...I am open to them all...
