Protect your tank's layout and fish during water changes with this floating flow diffuser from BlubberCove.
Crafted for aquascapers and nano-tank keepers, this tool reduces the pressure of incoming water, softening flow and preventing substrate disruption — especially important for shrimp, betta, corydoras, and planted tanks.
No suction cups or mounts required. Just place it in the corner of your aquarium, pour water into it, and it floats gently in place, dispersing the flow.

Quick delivery, items are as expected and good quality.
Got this as a gift for my husband and he loves it! Great quality and fits a ton of cards.
My betta loves to make his bubble nests in here. And while he is not a long finned fish and doesn’t use it for resting, he does love to hang out in it. Only additional thing I did was get different grit sandpaper to smooth out the inside so nothing like loose filament would catch on fins.
Well I brought it for frogs, snails and fish. Didn’t know if they’d take a liking to it as that isn’t the intended audience but… wish I could add multiple pictures. Everybody adores it! I tend to keep it fastened down to one particular spot, as they’re less responsive when it’s floating around everywhere. Glad they enjoy it!
Absolutely perfect, what I expected! Pepper enjoyed wearing it, he didn’t even try to take it off!
Product was a good gift and is sturdy, however it is noticeably 3D printed, but not that big a deal
This item is excellent and exactly as described. Perfect for my bettas. They love them.
Works great and is easy to clean. I like that it's a single piece. It floats well and doesn't kick up the sand. I'd previously purchased a stick on diffuser with a swappable base, and it's not nearly as user friendly.
