Perfect for small tanks
This cleaner isn’t the fanciest out there, but it’s by far the smallest I’ve seen, and that’s what makes it great. As long as rock isn’t smashing against the glass, you can pretty much get everywhere with this little cleaner. Without it, I’d have a lot of algae spots all over from having to avoid tight spaces with my larger magfloat cleaners, or I’d have to get in there manually which might just be even messier. Definitely recommend if you have a nano or pico setup to clean with tight spaces to deal with.
