Review: Excellent filtration at a great price! - Tetra always seems to make the best budget and just overall filters. I bought a bunch of the cheap usb pumps with filters elsewhere and I kept having algae spikes. Then I bought the tetra whisper and changed the filter out once and my fish tank has been clean ever since. Paired with the whisper, the filter is silent as a mouse. The filtration is excellent as mentioned. The filter doesn’t restrict the suction of the pump at all. It is functionally perfect and the assembly was nonexistent - put it in the pump assembly and away it goes! Will purchase again.
Review: Good buy - Had kept my fish tank clean
