Like anything else there is no such thing as not failing on you.even the red dragon pumps are failing sometimes. I have 2 of them dc 12000 as my return pump,dialed down to about 75% and another dc 3000 for my reactors. There are running for about a year without ever having a issue with themost.dead silent and berly any heat added to my tank.with the old mag 7.5 the water would rise much higher. I was septic at the beginning but I don't regret buying them.even the wave makers I have them from jebao,2 years and no issues...
