Question DIY waterfall?

I'm hoping to add a waterfall to my terrarium, but the ones I've seen for sale are not very attractive. I was thinking about constructing one out of the foam stuff they use for filling in space behind drywall, but I'm worried about it being toxic to fish. Any suggestions?

Well, if it's the same stuff I'm thinking of, there isn't a toxicity issue with it. There's folks on the SW side of the hobby that have used it to make real "panels" to reef tanks and embedded pieces of dry coral, etc. to it. I don't recall what the experience was with it over the long term though; as in did it start to break down, etc. But bear in mind that FW and SW do very different things to the same materials.

I would be curious to read what the experience has been wit it on the FW side.

As a suggestion, I think you can accomplish a great deal with just flat rocks, a tube of siicone adhesive, and some imagination. A limiting factor may be finding just the right pump.

Try this, supposedly it's black or dark grey (as opposed to yellow) and exactly meant for your application.

Here's a good example of what can be done with that, a mudskipper paladurium. It's pretty incredible, and uses the material for your intended purpose.

I first made a "water column" out of thin acrylic, then foamed over that. I painted it with the rock-looking spraypaint then did a clear coat over that. Didn't work so hot. I'd recommend some sort of epoxy covering instead. The best part is that the heater and UV are completely hidden (last pic), and it's a great place for me to add dry ferts without worrying about a fish taking a big mouthful.

The land part is eggcrate covered in great stuff and silicone. There's a little lake the waterfall drops into and then a little stream to the main area of the tank. They have slate on the bottom. After construction I also added those slate chips to the waterfall itself...else the water just kind of runs down the foam. It looks much cooler cascading over the pieces of slate.

Oh and the return pipe is PVC built into the foam, with a sponge-covered intake on the bottom of the tank, and a 90 flared barb at the top to slide the hose on.
