diy removable waterfall

[sawzall]

Looking at getting a zoomed 12x12x18.

I want to make a waterfall that is self contained like the ones that petsmart sales.

I want to make the footprint as small as possible.

I considered taking a rubbermaid food container and making the waterfall out of great stuff pond foam and egg crate. I have a small fountain pump.

Does this sound crazy? would I need a filter if I change the water a couple times a week or so? I want my green anole to use it as a water ball and as a cool feature. He would be able to drink out of it right?

Considered the egg crate false bottom and waterfall but not sure how to clean the bottom of the terrarium and how to change the water. If I went this route should I use a fountain pump or an internal filter pump like the duetto?

thanks

can anyone tell me if i can use the black great stuff without any problems?

what to paint it with and would that have to be sealed?

thinking of just doing the false bottom and making a small pool in front corner.

dont want to crete or carve just want to spray and paint is that possible?

thanks

Honestly... with such a small tank, don't bother with any types of pools or water features. That's one of the biggest beginner mistakes we've all made. No matter how much planning you put into it, you're going to encounter leaks and evaporation. Water features just aren't that much of a necessity to justify the hassle. If you had a 150g tank, then it might be worth considering, but not on something that small.
