Hey thanks
@EverAquarium, it's great to get some love for the build! The cabinet needs no reinforcement as it is technically a kitchen cabinet that is rated for more weight than the 20 gallon tank fully stocked (each leg supports up to 250 lbs, and I have 6 which translates to 1500 lbs and a fully stocked 20 gallon would be maximum 200-250 lbs ). Additionally, I choose to go with a split cabinet so there would be a middle divider to provide additional support from bowing for the top. The cabinet also cost about 1/2 the price of the innovative marine branded stand. The best part about this is that Ikea cabinets have many different configurations that could support a variety of tanks and desired layouts, however, my personal recommendation would to go with OEM cabinets for anything larger than a 40 gallon tank as they are built specifically for larger weight capacity tanks and engineered to those specific needs.
