NoClean Aquariums: Eco-Friendly, Self-Cleaning, Glass Fishbowl - GravityFlow2

The tank seems to be on the heavy side but durable. The design and function is that of a p-trap on a sink. I purchased this because being able to simply add water to change the water is much faster and cleaner to do. I did test the function and added water after it was filled all the way and it will lower to the design level on its own draining from the bottom along with any dirty flakes not eaten by fish. I am currently using this with a tropical tetra along with a mystery snail and a live plant to help with the oxygen and trying to avoid an air pump. The design on this is very basic but I was after the idea of no mess. I will update on the clean after a week to see if this will work.

I like the concept but the reality is this. When you pour the water in you have to do it slowly, the fish factor and the water spout is only so big and it takes awhile for it to drain. This is only going to clean it if the dirty stuff goes under the dome at the bottom under the rock a lot of it doesnt. Maybe im suppose to train the fish?

The no clean way of cleaning the tank does not seem to function quite as well as demonstrated. Yes it does flush water and some of the dirt but much of the dirt stays in the bottom. Great concept but it falls short of functioning as described.

I purchased this tank last year because I liked the concept and I have seen similar smaller tanks advertised on TV but they were lower quality. I have a betta fish in the tank and it does not clean as well as the description boasts. Most of the waste settles on the bottom and does not filter out of the spout when you add water. As a result this causes bad water quality and you eventually have to change the water "the old fashion way". I do not feel this is worth the money. I plan on purchasing a small aquarium with a filtration system for my fish.

Do not waste your $The gravity flow cleaning system works in theory, but only gets out 1/3 of the debris. I still have to clean this tank as I would a regular filterless bowl every 2-3 weeks.

It is Not cleaning the water I'm not sure what I'm doing wrong if anyone else got it to work I love the look of the tank but cleaning function is not working

Not very impressed. Did not get all the waste out as shown.

Doesn't work
