Do any of you know if someone makes a manual fleece roller for a larger tank? I've seen them for smaller aio but not for larger tanks. I love the idea of a fleece roller but do want the automation not to mention upfront cost. I dislike the automation more than the cost really. I don't really care if I forget to advance it and water overflows back into the tank as that's no worse than when the socks start to overflow which is ussualy when I decide to change them.
