Just thought i would share this
Wanted to make a background for my new(secondhand) 6×2x2.5
Had a look at a few different ways of doing it and ended up mixing some ideas from backgrounds that have been made
Got some poly from the WIZ for free Thanks Mate
What do you all think?


Step 1 cut poly to size of tank
cut random pieces of poly to make rock shapes and glue on top of each other with a small blob of silicone

Step 2 go over all the edges with expanding foam The stuff that comes in a pressure pack
Spray random foam over back ground to make other features
Step3 melt away poly to make caves note spray foam will not melt
smooth down foam with a wood rasp/file
Then when you are happy with the shape cut into sections to fit in tank
openings

Step4 render all over with premix cream mortar

Step 5 add some colour to next coat (cement Oxide) and do some more use different colours to get the shade you want i only used two
Black & sand stone all done using a brush


Step 6 seal with pond sealer i sprayed it but you can also brush it on


Step 7 Silicone to back of tank
render up the joins and seal with a brush
Leave for 7 days before filling with water
HAVE FUN
Regards Cobby

hey guys .. did you seal the back as well before you put in the tank.
also jesse .. you should have some kind of pond sealer there in home depot .. ask in there or a plumbing store.
