This is awesome and has given me an idea. I have a 75 gallon FW
built in aquarium in the master bedroom. Previous owners installed it, and I like it, but the master bathroom fixtures arent geared towards hooking up aquarium equipment for water changes, so I am running 75 ft of syphon hose from the kitchen to clean my tank. Luckily, directly behind the wall that has my aquarium in the master vanity sinks, and below my aquarium are sparingly used cabinets. I think I might cut a hole in the back side of my cabinet, tap in to the vanity water supply and drain, and set up my own dedicated aquarium water station.
Thanks for the motivation!
