i've fix quite a few tanks in different ways but no more then 300 litres and never a base. this tank is 8x2.5x3 foot tank L H W base is cracked all through. a new pane of glass is probably most reliable option but pricy at that size i m thinking of maybe using 1 inch Hardwood plywood sealing 5 inches of each side with water proofing and replacing glass with that but then glueing a whole 5 to 6 mm acrylic sheet on top sealing the edging with aquarium glue and hoping the plywood will be stronger then a think arcylic sheet instead since glue that to glass doesn't work out to good
