Here goes... I have developed a mild obsession with this in-floor shark tank from a mansion in California. The concept is to depress slab some 30" and have a Fowler tank withs small aquarium sharks, skates and fish. Full disclosure, I have already applied for building permit with this tank designed in my slab. We renamed the area "garden" because of the heckling and also I imagined the trades doubling their prices on a house with this kind of silliness. That said the construction is sound. I am in commercial construction in concrete and waterproofing. There is a mechanical/ room 14 feet away. I was planning on sand filtration as well as monster skimmer... What are your thoughts?
