Title: Hydor Koralia #4
Product review: A great pump, easy to mount and good water flow. I had the Aqua Clear 70 pumps before but over time they kept falling off the glass. I got tired of it and found that these pumps have better water flow are less cost, also with the magnet they never fall so it will not damage anything. Overall I am very happy with this pump. Only regret is you need the 12V version if you want to hook up the programmable wave-maker.
