Review on Hygger Quiet Internal Power Fish Tank Filter for 5-16 Gallon Small Aquarium with Hose - 3-in-1 Filtration, Oxygenation, & Water Change System by Audrey West

After a month and a water change the filter is not hanging straight down. It's crooked at an awkward 20 degree angle, which spoils the look of the entire tank. Aquascaping is hard work, especially when trying to keep everything balanced and natural. A permanently crooked internal filter is the LAST thing you need. Also a month later, he started making those demonic gurgling noises. I made sure all water levels were in place in the filter. Everything was clean, nothing stuck, the filter material/sponge was there. This product has serious design flaws. You will of course become explicit after it is no longer returnable/returnable.
