I’m getting ready to set up my older 125 gallon fish tank. It needs to be cleaned. Dust and dirt have been accumulating inside it over the years. Normally I would take a tank outside and hose it down. Mines in my basement and I’m by myself so I can’t bring it outside. What’s the best way to clean out the tank. I do have a new spray bottle I can add water to or some kind of safe solution to clean the tank. Any ideas?
