Review on VIVOSUN Submersible Fountain Aquarium Hydroponics Fish & Aquatic Pets ~ Aquarium Pumps & Filters by Paul Rumambi

12/19/2019 I really cannot recommend it due to the size of the device. I bought two Vivosun 210gph units and one of the Ecoplus 130gph units to use as hydroponic pumps. I'll try to remember to update it when I use it for a while, but my first impression was lackluster. Update 04/16/2020 I have changed my two star rating to five star rating. I did my first grow with these little pumps and am impressed. I really thought they couldn't take it and they did. They're small, but if you're short on space, I say go for it.
