Review: Better for the larger small tanks - This is a great product that works off a premise so simple, it's the same thing as flushing a toilet. I added this to a small fishbowl that one of my coworkers had two Bettas in and was always disgusting. It was small and easy to implant, but it did take up quite a bit of the swimming space in the fishbowl. Needless to say, they did not like it. In the meantime my coworker left the company and I inherited the fish. I upgraded the small fish bowl to a gallon and a half tank. At first the fish weren't eating and several people said I needed to turn the filter off (it creates bubbles), because it was bothering the fish. I turned it off. After about a week of the tank unfiltered, it was disgusting. Normally I would just change the water but instead I decided to plug the air pump back in and give the filter a chance. Amazing difference. It cleaned so amazingly and the fish have adapted to their new, clean bubbly environment. In the wake of this I discovered a few things, regardless of what anything says fish don't like scummy water. They like clean water. Bettas are marketed as fish who can go in small undecorated bowls that can get wicked nasty before you need to change the water. This is total b.s. Can they survive it? Yes. Do they like it and are they healthy in it? NO! Fter their water. As a pet owner you are their guardian and they deserve a good life. We all need clean fresh water to live. Freshwater fish are no exception.
Review: Great product - Love these. Small and work great in my 20 gallon tall

### ⭐⭐⭐ This could easily be a five star review
*by R***R on May 9, 2022*

I have a new, clean tank and I can't get these suction cups to stay more than a few days. This is a fatal flaw.
