Review on AquaClear Powerhead Gallons Hour Listed by Tyra Comeaux

My first purchase of the AquaClear 70 Powerhead was satisfactory. for some time. The flow was strong and the Venturi valve provided stable ventilation. This didn't last long, however, as the venturi valve quickly failed - bubbles stopped appearing. The device then started to freeze intermittently and I had to bring it back to life by shaking the device and finally tapping the device until it turned on. Why? Eventually it stopped completely. A further inspection revealed a malfunction of the impeller. After several unsuccessful attempts to find a new impeller, the rapid cloudiness of the water in the tank prompted me to make a business decision. I ordered a second device and an inner voice asked itself: Am I really giving away good money for bad money? Turns out my inner voice was right! The second device arrived and after connecting it I was immediately disappointed. The venturi valve NEVER worked. When it actually worked, the power from the powerhead was a faint trickle, even rarer than its non-working predecessor. So today I'm 100 euros lighter, have two defective devices and dirty water in the tank. I've attached a video showing how the current block is in its current (non-)operational state. The only thing that flows is my money from my wallet! Unless you're a punishment eater like me, my recommendation is DO NOT BUY!
