keeps my turtles tank clean
for its size and its price is very good pruduct

Moves a lot of water for it's size. Not sure how well it acts as a filter (just sponge), but in terms of water flow, this thing really packs a punch. Generates a lot of water movement in a 2 foot ~26L tank. I didn't find it very noisy.

looks like fragile and weak becouse of its little size, but it's a very well made pump that really help to flow the water of the tank. The sponge stores dirt and waste of food, enough to clean the sponge occasionally, I really reccomend this item.
