How to remove or install the filter?

Squeeze the two buckles at the same time, press them hard toward the center of the product (toward the bubble), and then push the protective cover-up.

How to maintain is required?

1. The sponge needs to be rinsed every time it gets dirty (approximately every 2 to 4 weeks). No need to use tap water, just gently clean the sponge with aquarium water.
2. After 3 to 6 months of use, the pores of the sponge will gradually become clogged with fine debris, and the sponge filter will begin to fail.
3. Therefore, it is also recommended to replace the sponge every three to six months or when the sponge is worn out.

Customer Reviews

Classy Looking, Great Tiny Bubbles, Sturdy, Nicely Made! Review by Tristanicus
Came nicely packaged. The stone comes with 2 suction cups and a mount for the stone. I never had this fancy of a bubble stone before. I usually bought ones that you place or try and hide but this one looks classy, very clean. I like how you can suction cup it anywhere in the aquarium. If you want bubbles on the top half of aquarium, attach it halfway up the aquarium. I was used to just buying the stones that lay at the bottom of the aquarium so this was a nice surprise. Really lets you make your aquarium look unique. Came with a yellow regulator valve, so you can control how much or how little bubbles you have in your tank. It’s a fancier valve then i had before, its a good size, easy to twist and even includes a seal inside for leak proof operation. (Posted on 2/23/2022)
