Inserting Water/Land Divider

[Super_Snapper]

I've decided to set my tank up as an aqua-terrarium. My plan was to simply get a piece of acrylic cut to match the width of my tank, and glue it in as a dam. Unfortunately, no business in my area cuts acrylic. I found one that will cut glass to custom measurements, but I'm not sure if I could use a glass dam in an acrylic tank. Is there anything that will glue/seal glass to acrylic?

Why not use an insert instead of all this hassle.
Find a plastic box such as a shoe box or something similar that will slide into your tank. You could even use several such containers even making an underwater cave with something spanning a couple of the inserts!!!

I did exactly what your doing now. I just used a table saw to cut the acrylic, then I used gorilla glue to hold it in. Gorilla glue claims to be water proof, but its not water tight, as it is similar to a foam. After that, I just put a bead of silicone around the edges and it works fine.

As for making the divider look decent in a tank, I just glued a long piece of cork bark on the water side. This adds a very nice effect. You can see pictures of the tank in the tree frog forum.

I don't like using this method as it usually looks unnatural, and usually leads to all the water on the pond side wicking up between the glass wall/divider angle, and soaking the soil on the terrestrial side. Plus you should have a way to control the amount of water on the terrestrial side as well.
I like to use tall pieces of rock siliconed to the bottom of the tank to form the shoreline. It holds back the land separate from the soil, you can make it any height, and it looks more natural as you can make the shoreline any shape you want. And you can even create multiple shorelines depending on the size of the tank.

I agree...the divider would throw the whole thing off...if you are concerned with the dirt getting in the soil add a layer of crushed rock to the height of your water table and add a screen on dirt of that...think i have seen some people do that

The whole look natural thing troubled me at first too about the divider, but if you attach a piece of corkbark along the whole thing, it looks really good.
