my diy 3d background

-sheet of styrofoam insulation
-cement mix. i used a bag of patch cement from menards
-cement die of your choice
thats it!

step one- cut your sheet to fit the back of your aquarium. if you have a support you will need more than one sheet.

step two- cut out peices of left over stryofoam to look like rocks and glue them onto the sheet. look at pics of canyons or something to get ideas.

step three- mix up your cement to be really runny and cover your background with it. a brush will help with this. do around 2 to 4 coats

step four- let dry for a long time

step five- put inside tank and silicon it inplace. if you had a support panit cement mix over the seams of the seperate peices inside the tank. cover bottom of tank before this

now let it air out and dry. then add water. this may mess with your ph according to some people but i didnt have a problem. if so just let water sit in the tank and keep doing water hanges till it gets better

the pic is of my 55 gallon piranha tank. had background in their for a couple months with no problems

awesome thinking. i was wanting to silicone some lava rock to the back of a 5.5 for moss.. but if i can just spackle some concrete on the back.. hmmm..

flashbacks to pouring concrete with the step-dad... foam thingy.. what is the foam thingy.. expansion joint.. note to self: do not blindly pour concrete ready mix into empty tank...

i think your idea will work well long term. just keep doing your regular w/c schedule so the concrete doesn't put off too many minerals. a 3d black concrete wall would be sick with some moss and ferns on it.. you could even fashion little cup like indents in, fill them with some high CEC soil and plant stuff on the wall.

edit: your post still pertains to the scape of the tank, regardless of how awesome it is to do things like this by yourself. don't sweat it.

that turned out real nice. great job

There are 2 types of people on this forum. Those that have algae, and those that lie and say they don't.

Looks great!

I would be worried about it affecting my water chemistry though. Perhaps a spray on clear coat to seal it? Like Krylon Clear Coat?

Any way good job!
