We have a 90+ gallon tank for our aquatic turtle, and, there are goldfish in there, as well, so, we needed a good, heavy-duty submersible system. We figured that two are better than one, with the grossness that these creatures emit, and, we set them up on two sides of the aquarium. Cleaning the filters each week, I've taken great care not to burn out the units, yet, last week, one died. This morning, the other one died. These are less than six months old. We invested in these because we thought they were heavy duty enough, but, apparently not. I'm so disappointed that we wasted over a hundred dollars for six months. Products shouldn't fail so easily. … more
