Bests & Worsts Reviews from Amazon

There are plenty of detailed reviews on the original Fluval Edge. This one, with the 21 LED lighting is the newer model, so when I decided to make my purchase I went with this one, even though it's several dollars more. Personally, from all the comments regarding the lighting issues on the previous model I wouldn't hesitate spending the extra money and opt for this newer model. In reading the other reviews, there isn't much that I can add that hasn't already been said. However, these are the things that I think are major pros and cons: Biggest Pros: The lighting expands throughout the tank - from edge to edge, not just in the center. Better design if you're keeping live plants. Plus, the lights don't get warm at all. The blue night-lighting is a very nice feature. I use this setting about an hour before I go to bed and it's really relaxing to watch the fish swim in the blue light. The tank itself is the coolest design I've ever seen. It is extremely impressive to view, and gives the feel of everything being almost weightless. Very soothing. Biggest Cons: As everyone has stated before, the opening is small, but I can reach my hand inside from corner to corner without any trouble. Something to think about, though: I bought the bamboo wall accessory and it made the opening even smaller, as it sits right below it. I ended up removing mine and stuck with live plant and rock decorations. It looks just as nice that way, and I have more room to get into the aquarium when needed. If you want to do any cleaning or need to stick your hand into the aquarium for ANY reason, you MUST remove some of the water first. Otherwise it will spill out of the opening and all over the place. Bottom line: if you are looking for a tank that is visually stunning to look at and want something completely unusual, you won't be disappointed IF you can live with the few quirks this tank has. If you like rearranging your tank or need to get in and out of it quickly, you may find this more annoying than its worth. I've kept tanks on and off for over 15 years and for me, the beauty of it outweighs what some people would call a nuisance.
