dividing a terrarium for a pond

Posted by raymond1953 MO (My Page) on

I'm on an assignment. My wife has a glass aqauarium in which she keeps four tree frogs. She's spent months playing with various fountains and pumps to create a waterfall and finally has what she likes. It sits in about 4" of water at the bottom of the aquarium so the only dry land that remains is what she's created on rocks and plants. She wants me to add a 6" high divider so she can keep one end of the aquarium dry with a pool at the other end with the waterfall fountain. She's even brought me a tube of aquarium silicon to use.

Rather than glass, I thought that polycarbonate (lexan) or acrylic (plexiglass) would be safer and easier to work with. Are either of these materials particularly good or bad for this purpose? How thick would you recommend?

Are there other ways to create a pond? I thought about using pond liner and small stones, but most pond liner is pretty thick to form into a small pool like this. I don't want to create a lot of work for her to rebuild the pond each time she cleans out the terrarium. Can I glue the stones in place and will they stay put with silicon?

Thanks for any advice or ideas you can offer.

I would recomand either glass or a polycarbonate material, I find acrylic to be way to crispy and faster degradeing then polycarbonate.

If you want somthing that never breaks use laminated polycarbonate, thats the same used for bullet proff windows ect. Just get a thin sheet, like 4 - 6 mm. or something.

Personaly I would use a 6 mm hardened glass, as it's alot harder and don't get scratched as easy as any of the two other materials. Here polycarbonate would be alot more ekspencive too, but it's a super material!

Build one out of expanding foam, them cover it with silicone and your choice of either coco fiber, gravel and so on, its permanate, and when your wife cleans the set up all she has to do is clean arouind it =) the directions on how to do this can be found on, just adapt it to build a pool from the same process, Ive done it in the past and it has worked out great =)

They make kits fo this purpose for several sizes of aquariums. I always found it almost impossible to keep a "pond " full of water. No matter how carefully planned the water seems to miss it lol. The best bet is to use a false bottom and raise the substrate above this then you can set a bowl or whatever in it. Direct the stream toward it and the water will be constantly changing. Won't matter if it goes over the side.
