Review on 🐠 HiTauing Electric Aquarium Gravel Cleaner - 317GPH, 24V/24W DC, Automatic Fish Tank Cleaning Tool Set with Removable Vacuum, Water Changer, Sand Washer, and Filter Changer by Brittany Wallace

If you have gravel your reservoir needs to be over 30cm high or the hose will not be able to fill with water and will leak. The filters at the end work right away, but the compartment is too small and fine sediment, algae or fish droppings, snail eggs, etc. All of this will clog in the purple filter, and you'll pass about 1 filter pad per 10 gallons. It's absolutely useless for a tank of 80 gallons and up. The design is a "chef's kiss" in my opinion, but the curves need to be finished. But for 80g and under it's perfect
