lilly1958 Posted September 8, 2013 Report Share Posted September 8, 2013 I decided to upsize my 2ft to a 3ft & bought one secondhand from a QLDAF member & was told it was 3ft. The cabinet I have to use is exactly 90cm long. Well it turns out the tank is 100cm long. My question is will the tank crack if it has an over hang of 5cms at each end? If so does anyone have a decent looking 90cm tank they would like to swap for a 100cm one??? Cheers Lisa Link to comment Share on other sites More sharing options...
BigPete86 Posted September 8, 2013 Report Share Posted September 8, 2013 You could buy a piece of strong flat timber 1000mm long & ...mm wide. Paint it in a marine proof or water proof paint & it'll hold the edges. I don't think a 3 (& a bit >x<) foot tank has enough volume & therefore enough mass & pressure to worry bout 50mm overhang each side popping the seal or breaking the tank but if it was me I'd get a piece of 12 or 15mm thick marine ply on the cheaper side or a good flat hardwood plank or 2 on the more expensive side...

lilly1958 Posted September 8, 2013 Author Report Share Posted September 8, 2013 Thanks BigPete, That's what I was just thinking while I was sitting here looking at it. I'll need to get a bigger piece of foam to put under it as well grrr. Looks like it's off to Bunnings in the morning.. Cheers Link to comment Share on other sites More sharing options...
