Review on Boxtech Hang On Filter Aquarium Power Waterfall Suspension Oxygen Pump - Submersible Activated Carbon Biochemical Fish Tank Filtration Water System - Wall Mounted by Nicholas Gendron

I think I've found the best filters for my Betta! I used sponge filters. But the air pumps were very noisy. So I found these 5-10 gallon clear HOBs from Revain for $10 each. While they are amazing! Very quiet, small. They don't take up as much space as you might think. Comes with a sponge to clip onto the inlet tube. I only recommend buying more sponge material as there is a lot of space in the filter where more material could be used. Ps. They can also increase or decrease the flow at the filter so it's not as strong for them. 🐟
