Yes, just take it outside in the yard on the grass & hose it out real good. It's easier to do it outside & then take a scrubby pad (one that has never been used with soap!) & scrub all the algae, salt creep & stuff off. After I’m done scrubbing out the tank I usually stand it up on one end & spray down all four sides inside the tank & then flip it over to the other end & do all four sides again. Be sure to get a good grip on it, as wet glass can be slippery. (That’s why I do it out on the lawn, if it falls over the grass is a lot softer than the driveway - just be sure there are no rocks in the grass!) And never grab it by the center cross-brace as I have had the brace break from the weight of the tank. Also be careful about grabbing the plastic frame, I have had several ones come off the tank - usually the bottom one. It's no fun having a tank slip out of you hands & you are left holding the plastic rim part & the tank goes falling in the other direction! I do the equipment in the kitchen sink, where I can use the spray wand with warm water & a new scrub brush (again, one that has never been used with soap!).
