SamH Posted September 13, 2009 Report Share Posted September 13, 2009 Poly helps take up irregularities and any peices of grit that may be under your aqaurium. Even a little stone under your tank when filled with water will crack the glass. It can be anywhere from 1mm up I think, might have to get that one confirmed. My thinest peices are about 1mm thick. http://www.trademe.co.nz/Members/Listin ... er=1269975 <--- He's really good. Makes tank and sells poly. You can also find it at places liek Noel Leeming and Harvey Norman I'd imagine. It doesn't have to be polystyrene, camping rolls will do. You can get them from the red shed.

smidey Posted September 13, 2009 Report Share Posted September 13, 2009 it also helps to level out the tank to stop additonal pressure being placed on one side of the tank. You can get it from payless plastics, 2.4x1.2 sheet of 8mm is $8, great for insulating the tank to. for a 2 footer i would use mimium 6mm.

smidey Posted September 18, 2009 Report Share Posted September 18, 2009 your not going to need it with a 5 litre. 60 litre i thought would need some, its a glass tank? the problem with glass is that if you stress one area i can crack so the poly help level the tank & also stops small debris pressing on one area & creating a stress point.

Will work out a way so I can put it down under the tank. Quote Link to comment Share on other sites More sharing options...
