[Wet Thumb Forum]-DIY background/styrofoam (pictures)

[imported_Lomax]

Hello all,

I have been working on a ~ 300G DIY plywood tank and will have a Styrofoam background also.

A better way to do the background is to coat the styrofoam with cement, just thin it down till it is like soup and mix a bit of sand and pat it on. It covers the pink color and gives rocks a nice texture. Then you can paint it over with WestSystems epoxy, but you should only use there color additives! Mixing in something else may have a bad chemical reation.
It could just change the color or worse make something toxic out of the mix, if you have question just call WestSystems and ask them what you can add.

I was looking to make this project but i cant seem to find the epoxy and the silicone locally, with the exception of the silicon made specifically for aquariums which is like $5 a small tube. Too expensive for me!! I can only find the small little squeeze bottle of epoxy. Is there any alternative to the epoxy and any other brand or type of silicon that would be good for this project? Would really appreciate any input because i have already cut the styrofoam and am just waiting on the rest.

Tito,

As I stated in initial post, Epoxy was the most expensive thing in this project - $30.

I don't know where in Texas you live but you can get West System brand in the following towns.
