Negative Pressure Aquarium Fish Tank Cool Fish Tank Aquarium Water replenishers Water Level auto-Refill Maintenance

Very sturdy and comes with a way to truly hold it well. My betta loved it instantly .

Got this floating island for the negative gravity chamber in my fish tank and out a glow in the dark moon sticker on my auto feeder behind it.. Reminds me of avatar! Looks awesome! 😎

So it does fit my standard tank with a plastic lip - barely. And it is a functional thing, but the quality of the materials is a bit shoddy. Its clear acrylic and the supporting pieces have some pretty big air bubbles which is a little concerning. It does sit crooked in my tank, not sure what to do about that. It's a little challenging to install but that might have user error. Overall its worth it for the novelty factor.

Obsessed. Easy to “install” with clear instructions. My fish immediately used it and it adds a good amount of space to my small 6gal tank (About half a gallon). Looks fabulous, high quality materials, seems stable (only used 2 of the 3 provided hooks due to a corner piece on the tank)

Smaller than I thought? Didn’t latch onto my tank very well

Does what it’s supposed to do.

Its is very kool to use but I can only use it for a small amount of time. I have betta fish and they mostly breathe air from the surface and inside this container there is no air so it becomes scary for me and my bettas.

My betta loves it, its his little pent house to the rest if the tank

Great price and was super easy to set up ,very clear and my betta loves it!

Amazing quality, easy to install.

Works well. Check valve is a must

Works as desceibed
