Review on Newpet Thermo Sponge Aquarium Biochemical Salt Water by Melissa Hill

Doesn't seem to attract air and water as evenly as a traditional sponge filter given the plastic slots and is larger than the description suggests, definitely a bit big for my 5 gallon. The foam is pretty good so it needs cleaning more often than the ones in my aquarium chicken coop. But. It works great and I need to check the size first. My shrimp love it and it fell into disrepair quickly when my old pump broke down and I had to install a filter asap!
