Review on 🐠 TERAPUMP® Genuine Aquarium Fish Tank Gravel Cleaner - Long Nozzle for Effective Cleaning and Water Flow Control by Jennifer Neff

Water filtration: Very good. The pump works as advertised. Substrate Cleaning: Very bad for sand - can't speak for gravel Length: It was short for my tank size but I added an extension and it worked like a charm Quality: Fragile - I doubt it will last very long Water Flow Clip: Works as advertised. Delivery: Arrived well packaged as promised. I can't speak for Gravel, but if you have sand as a surface, buying this product is not worthwhile. But if you are looking for a quick water siphon then by all means buy it.
