Review on Upettools Silent Energy Aquarium Silicone by Ruth Reiners

We have a rooster and a rooster. Wow, these are pretty. We bought the pump for our own peace of mind and for the health of the fish. We have aquariums. During the first two weeks, the male gnawed off most of the female's lower fin. That's why we made her a second aquarium out of a large transparent vase. Then we bought a bubbler pump splitter. That works fine. You can see that they are recovering a lot of oxygen from their marine environment. She emerged victorious, with a more difficult 'castle' to swim through and her own decorations. She loves popping bubbles, whether it's to increase her oxygen levels or to play, who knows? I'm just amazed at how responsive they both are when we drop by after work or when we wake up in the morning. It's fun and the pump is an integral part of it. Highly recommended. I do not hear. I'm pretty sure I could by listening to it, but I don't do it on a daily basis. This is after we got our first aquarium back precisely because it was too noisy. Our apartment is on the 4th floor with no side or upper neighbors, so apart from the usual traffic noise, it's very quiet here. We couldn't stand a noisy device at the bar between the kitchen and dining area. This is where we spend most of our time. We love to linger around the dining table for a quiet chat after dinner or breakfast on weekends. We don't hear the pump.
