Sounds like a top plan to me mate!It would simply be a case of replacing the 2ft with the 2.5ft. I have it all planned out already.
The plan would be to have a base layer of aquatic compost, then a thin layer of sphagnum moss and some osmocote chucked about then finally a top layer of cat litter. Then plant away until the tank was packed solid... again!! Then upgrade to my 3ft... then a 4ft...
