Review on 💧 Optimized Fluval Pump for EVO12/Flex 15/Spec 16 by Rachel Wilder

The pump for my Fluval Flex 15 was fading - took it out and cleaned it thoroughly which helped. But after more than 2 years I finally needed a replacement as the pump was struggling to suck water into the rear chamber which meant the water level in the front chamber was starting to rise dangerously. This is the exact replacement. The flow rate is improved over the tired original. It remains to be hoped that the service life will also improve compared to the original. Luckily I didn't need the tube pictured as the original was still intact so I just replaced it. I was considering 3rd party pumps but wasn't sure if I would need adapters for proprietary Fluval fittings/hoses etc and wasn't sure about the different flow rates. In fact, with the new pump, everyone in the aquarium seemed more alive, so I'm glad I replaced the pump.
