Ill guarantee if he borrows my hammerhead it won't work for him, t will feel like a mag float small being used on a bigger tank. His acrylic is almost twice as thick as my glass. I really think the great white will work but I don't want you to be stuck with it if not.man that seems like soooo much money for a magnet cleaner. y dont you borrow fish beards for a day and see how his works for you before you spend money like that or someone elses. just an idea.
