wellmax Posted June 6, 2009 Report Share Posted June 6, 2009 Can anyone explain to me why these tanks do not require a polystyrene base. It seems all of these tanks only sit on a plastic channel. This includes my UFO 880 which I have just purchased which holds 305 litres. The manufacturer states the only requirement is a perfectly level surface. Is this safe??

Barrie Posted June 6, 2009 Report Share Posted June 6, 2009 the compression in the poly will normally take up a slighty uneven surface as well as insulate it Quote Link to comment Share on other sites More sharing options...
fishybiz Posted June 7, 2009 Report Share Posted June 7, 2009 A lot of them have poly built into the base or a very thin poly underneath them - Ive never seen one without and we have quite a few. Quote Link to comment Share on other sites More sharing options...
Morcs Posted June 7, 2009 Report Share Posted June 7, 2009 My 620T doesnt have one. Just had a plastic rim around the bottom. Quote Link to comment Share on other sites More sharing options...
oeminx Posted June 7, 2009 Report Share Posted June 7, 2009 My 620T doesnt have one. Just had a plastic rim around the bottom. mine has, well its not quite poly but it does the same job, it sits between the moulded plastic base and the bottom sheet of glass.

Bananalobster Posted June 8, 2009 Report Share Posted June 8, 2009 Ive got a Aqua one 620T, if you look down into it when its empty (no substrate) you can see a thin layer of poly type stuff under the glass. The kind of stuff some people use to pack fragile items etc I think. It would look quite ugly if you put poly between the tank and the base with my one, glad they fit it between the glass and the moulding underneath. Just my two cents.
