Anyone have any opinions on the new hydor koralia pumps? I currently have 2 Seio 820's, (attached by suction cups). The Seio 820 pump with a magnet would cost $70 apiece. The equivalent with Hydor, (850gph), is $40 and they come with the magnets. Any history on this product line regarding durability, water movement, noise level etc?
