An infinity pool is probably out of most people’s budgets, heck even available acreage. Enter the Spillarium. While it’s a long shot from a pool for your own dipping pleasure, your fishies should most certainly enjoy it and at the very least you can live vicariously through them. A small hole in the front of the 5 gallon tank spills out water into the base and continuously recycles and filters it back into swimming area without off loading any fish. You can nab one for $130.
