Review on 🐠 TERAPUMP Nano Aquarium Gravel/Sand Cleaner (BPA-Free / Safe for Small Aquatic Life) for Aquariums Under 10 Gallons by Tony Baker

I've just received a 7 gallon nano aquarium which I'm in the middle of a cycle for the cherry shrimp I'm hoping to get and I thought , this little pump would work just fine. I liked the narrow suction tube because I have plants and rocks and things like that and I have to get around them. However, due to the way the rest of the tube is constructed, it's not easy to use. The ribs in it DO NOT add flex like I assume they are supposed to (I also assume that this type of hard plastic was cheaper but not worth it) but instead distorts the water flow and traps bubbles so it a) difficult to start suction and b) likely to stop suction once it STARTS. I ended up squeezing the bulb just to keep the water from escaping which was annoying and splattered my gravel everywhere.
