hygger Small Gravel Vacuum for Aquarium, Manual 80GPH Aquarium Gravel Cleaner Low Water Level Water Changer Fish Tank Cleaner with Pinch or Grip Run in Seconds Suction Ball Adjustable Length

I've kept aquariums for many years, and have owned many gravel/sand vacuums. This one is my absolute favorite. It is the perfect size for my Waterbox 20 gallon Cube saltwater aquarium. Every vacuum I've owned has caused spills at one time or another, especially when trying to start the siphon. With the hand primer it is super easy and spill free to start a siphon. Also the included clip is nice to keep the hose from coming out of the bucket. That being said, I ended up securing the hose to the clip with a zip tie as it can come loose. At first I was having issues with the primer not starting a siphon but found that if I disassemble and flush with tap water each time after using it works fine. There are two small check valves, one in the hose fitting and one in the inlet that I flush with tap water, if these get gummed up the hand primer won't work. Also make sure not to lose the two small clear o rings in the fittings when flushing.

Estuvo funcionando bien y es el día de hoy y a empieza a no sifonear

Easy to put together and use. Easy to take apart and flush afterwards (watch the little white washers inside some of the pieces though). So far it has been excellent to clean with. For a small tank the suction is alright. The tubing is nice and long so reaches drainage basin or sink. The gravel only gets sucked up so far and a couple of movements it falls back down. It is quite durable.

Compre esta aspiradora para supuestamente hacer la succión del agua mas facil pero era muy complicado aplicar presion a la bomba y que el agua no avanzara por la manguera. Despues de 2 dias de uso, la bomba dejo de jalar agua, me imagino se escapo el aire por algun lado de la bomba. Mejor hubiese comprado un siphon regular. No lo recomiendo para nada.

This is a perfect cleaning rig for a 20 gallon tall tank. The bulb to initiate the syphon works great. Hose is a little smaller than you want for a large tank but is perfect for smaller and heavily planted tanks. Comes with all the accessories needed. Materials used are quality and durable. Good buy for your money. Recommended.
