Terrarium Backgrounds In Aquarium?

Can this be used in an aquarium?

Way cheaper than normal stuff.

I would have thought so.

Alternatively do what i'm doing, make your own. Alls you need is polystyrene, something to stick them together, a knife to carve it and then cement or grout to colour weight it down.

Is cement safe?

Any tutorials?

Yes, can be. You do have to fill the tank with water and empty repeatedly for a week or two to allow the cement to leach out what it can. Then after a while it stops altering the pH of your water and is safe to sustain life.

I can't find any threads on here. There is HX's planted journal over in the planted journal section, they created a fantastic piece of custom 3D background, well worth a look. Then youtube it, you'll get loads of DIY 3D background how-to's video's come up on there.

very common on dart frog forums pop over there loads of step by steps

Any other thoughts on background I posted?

Looks good, im actually thinking of getting the Juwel one:

Looks Ok you just need to ask if the finished paint will stand up to water..
I made mine and coated it in epoxy resin and kiln dried sand.. instead of cement, I work with cement and its nasty stuff.
