DIY background (in progress)

Ahh, Ok. I thought maybe you were modifying an old or existing tank. My projects typically end with those forehead slapping moments when I realize I forgot something basic like that. My cousin once drove an hour to bring me his computer to fix because the sound stopped working. The volume was turned all the way down.
 
are you sealing the foam, or will it just be exposed to water?

off topic again, but i thought i would let you know that your puffer avatar inspired me... i now have 4 and will be getting 2 more when they come in! great little fish!
 
Have you ever looked into making plastic molds from layouts of real rock?

i dont understand you Slappy*McFish, my english isnt that good *sigh*

Spunky:
- Firstly, thanks.. those dwarf puffers are sure a cutey one..
- i wont be sealing the foam, i will let them exposed to the water..
they should be fine as long as my fish isnt going to bite it..
- that was a good question, but i havent known how much salt i must add
during curing process >< i would do some research in time to come..
- about the weight, as heavier as possible, i dont want my background to move even abit in the aquarium hehe.. and i heard from someone that
**it takes at least 25 pounds of metal to sink 1 pound of foam**
- isnt pink foam a better choice for carving? thats what i heard, but i couldnt
find that foam here.
- 5 coats of cement should do.. i will first coat it with 4 thin layers and followed by 1 thicker layers..

-Haha, thats remind me of something..
i was trying to close my fridge and it just refused to close..
i tried alot of things..
i pushed all the ice cube,fish,vege inside, remove all of them out,
slam the fridge and it just didnt want to close...
so i called my bro to go downstair, and he managed to close it in 5 seconds
u know what, there is a package of plastic on top of the fridge where it was slightly fall off and i didnt notice it ><"
