hi guys i decided to put the verry early stages on now and i will update it daily as i go...................
first start with your overall size of the back of your tank minus an inch off the length and height...then cut out multiple layers of polystyrene in rock shapes and overlay them onto your base board,(pic 1)
then mark lines in the baseboard using the point of a knife,about 20mm deep in the outline of rocks ,this bit is entirely up to you how you want the lines to look ,markig them out with a marker pen first is a good idea( pic 2)
then once all the pieces are cut and layered on the baseboard and the rock lines are marked on your baseboard ,
get a small burner torch and run it over all the pieces you have cut ,around the edges and allong the lines in your base board,(pics 4/5)
then cut the base board into sections that will fit into your tank but cut along the lines you marked not to see the joints (pic6)
the mark on the baseboard an number all the positions of the layer rocks so you know what goes whare and stick in place with aquarium sealant(pic7)....to be continued
