🐠 Zision Aquarium Water Pump Air Bubble Fish Tank Water Circulation System: Enhanced WaveMaker for Optimal Oxygenation (25W 500L/H) Review

Great accessory/auxiliary pump for a 'sick aquarium' or for extra filtration in a 'normal' aquarium. Very strong for its size, can really move water! Highly recommended.

There is nothing I don't like about this filter, it's quiet, cleans the tank very well; only needs to be cleaned once a month or less. Fish and frogs love it. I am very happy with this filter.

works great. The problem is that it needs to be cleaned regularly, about once a week, to keep it running at the same speed. adjustable speed is good. The fish loves to play and is very calm. no more waterfall sounds

Usually you have to clean the tank 3 times a week but as we had it within a week. We never had to clean. This will save me a lot on my water bills. This product saves lives. I highly recommend it.

The downside to this pump is that the filter is not easy to clean and gets dirty incredibly quickly. In our little fountain with 9 3 inch goldfish. loudly he fell sideways, which was more the case for our goldfish, since he has a current in the shallow water. I'm glad we bought. Ideal for our application.

Pump setting did not work. It was a wide open stream regardless of settings. Unfortunately, I bought additional sponge filters. spent my money Pool still cloudy after water change. I'm not sure what it's supposed to do other than push the water. I bought another pump and filter (not this one) and now the tank looks great. Wouldn't buy again.

I have a 2.5 gallon aquarium with a few guppies and some small goldfish. This pump offers adjustable bladders and water movement, but there's little filtration. I clean it every week, sometimes 2 times a week and change the water every two weeks. I am very disappointed in this product as the suction cups that hold the pump to the jar keep slipping and the pump almost lands on the bottom of the tank.

I have been using external tank filters for many years. I finally realized that I didn't have to suffer from scale/scale from fish water. I discovered this underwater filter! I love the bubbles it has, I feel it adds more flow to the aquarium and allows the fish to be in a more natural habitat. The bubbles ensure more oxygen-rich water. The price cannot match the quality. The downside is that the pump can be noisy with bubbles at times, but you have to adjust the height in the water, and that's

First review: Be careful when plugging it in! sprays water a few meters high. Noisy, but usually nobody sleeps in the living room. It was very easy to set up once I got the hang of it because the Chinese to English translation is one of the worst ever written. After a while my adult grandson and I were laughing too hard to continue working. There isn't much to collect and I decided to turn it on its side to keep the water from splashing. It's in a small aquarium for a green-eared baby I found…
