I'm sure there are better ways, but I've been cleaning my tank with a swimming pool hose and a vacuum head. After brushing down the sides, I let everything settle to the bottom before siphoning water through the hose, creating a vacuum. I bought the hose, extendable pole and brush at Walmart and the vacuum head on Amazon. Seems to work pretty good!
