My aqua lifters are years old. They only clog from algae growth, but using black tubing stops that. I have one black and one clear that still needs replaced yet. Love those things. And if it died, they are 15 bucks to replace. Hardly the most expensive replacement on any reef tank.

It's cheap and easy to setup and as long as you setup he overflow and the sump properly you won't have to worry about flooding if either the overflow or return pump fail.

Where most people have issues is that they don't leave enough room in either the DT or Sump to hold extra water should something fail. In my setup I have 10gallons of room to work with in the sump. Which may not seem like a lot but there isn't any possibility that my overflow would allow more water to drain if the return stopped working.

Edit: and to add another detail which was mentioned above. Your return line placement and fail safes are important as well to prevent back siphon. Which is easy enough...I know people use siphon break wholes but I think they are risky. I prefer to place my return (which is all PVC) just above the waterline with elbows. This way no water can back siphon because it never has the chance. If in the case your overflow stops working and then your return pump fails because it was running dry/low and the return line was submerged due to your return sump section being empty then water will only back siphon so much thanks to the solid placement of the return line. The other great thing about it is that at a certain point where the water gets low the elbow will naturally start sucking air and break a siphon on its own.

One thing I will say if you decide to go with this design is don't chance it with a suction cup drilled near the bottom of the weir. If that isn't water tight you could have massive problems. I skipped that altogether and never had a problem with it.
