Review on TERA PUMP Compatible Aquariums Controller by Cristabel Logan

Works as described. Came with good instructions. It took me a while to figure out that I had to pump hard and fast with both hands to get going and then it started flowing nicely on its own, freeing my hands. I cleaned my pebble base without disturbing it, but removed the dirt with a vacuum cleaner. I used to scoop water from the top, but it's so nice to clean it from the bottom along with the trash. When I'm done, I take a bucket and water the plants with water and fish shit.
