I bought this tank from our local aquarium store when I decided to switch from my bettas to something a little more high maintenence. Despite my reservations about its weight (even empty), the tank seemed great at first -- built in filter, built in heater and light, great design.Then came time to do a full water change.When this batch of fish dies, I will be throwing this tank in the trash. It is too unwieldy to work with it at all. After siphoning the majority of the water from the tank, I tried to tip the tank to get the last of the water and to start scooping out the rocks. Not only was it hard to find a place to grip, the tank itself was almost too heavy to move, let alone tip and maneuver.My recommendation is to just by a normal tank and all the accessories. This one just isn't worth the hassle.
