Did my own thing for my 125g , started with the stand , 4x4 for each corner and center front and rear . Used 2x12 for base support and 2x6 for upper . 3/4 finished ply for the deck upper and lower .then 1/4 hardwood ply to wrap it added some phigre for ascetics and the stand was done , oh all cross member were 2x4 , I did not bothere with a canopy , just glass and lights . Went simple on filtration , canister and UV
sterilizer only , never had any problems . That was a saltwater tank , I'm old school and like to keep it simple .
