I absolutely love it! But there's one thing bothers me...
My water garden was great! I loved watching the plants grow before I even got the fish! I think that it's a really cool idea that plant roots filter the droppings, and I don't have to buy a fancy filter. The plants don't just filter the droppings, but they also make the tank look ravishing!
The thing that I dislike about it would be that the pump vibrates the glass on the tank, and a little on the table, is this normal?
I also think that a three gallon is a little small for a male betta fish, so I recommend getting a female instead for this tank. And I would recommend to the company for them to make a five gallon water garden, I bet more people would buy them. Other than that, It's a wonderful way to filter droppings!
