I have been a hygger product fan, but now....
I have been a hygger product fan. All my stuff for my 6 aquariums are from hygger. From bar lights and risers, UV lights, heaters and even gravel cleaners foe my 75 and 55G. I used 60ml syringe to clean my shrimp tanks until I saw this hygger aquarium water changer kit for smaller tanks. I was so excited using it the first time. At least I can removed left-over food in my 5G shrimp and nano fish tanks. Unfortunately, the second day, it stopped suctioning, no matter how hard I squeeze it the debris wouldn't even move. Tried cleaning the bulb and the filter but to no avail. It is frustrating. I guess I have to go back to my DIY syringe with attached acrylic tubing. What a failure on your new product, hygger!
