I have two 37 gallon show tanks with Eclipse 3 light/filtration hoods on them. They are extremely easy to assemble and operate, and I love both of them, except for one thing - the very cool "all in one" feature is a drawback if you need to add extra filtration. No
HOB or clip on canister filters. The reason I mention that is I decided to use one of mine for a goldfish tank. Now I uinderstand why everyone says you cannot overfilter a goldfish tank. I have just added an internal filter canister, which is helping immensely, but asethetically, it leaves something to be desired.
My other one is a tropical community tank, and I've really had no problem with it. Of course, you wouldn't be able to plant these tanks, as they are so tall, and you only have 30 watts of light over about 35 gallons of water (exclusive of substrate and decor). Marineland was so very clever in making sure you have to use their bulbs that I can't see how you'd modify the hood to take compact flourescents. Which means you'd have to deep-six the hood you paid so much money for in the first place. Fortunately, live plants are not an issue in either one of my tanks, as goldfish will pretty much decimate live plants, and I've got some fish in the tropical tank which wouldn't be too friendly to plants either.
Just my opinions. . . If you like the tank, and are pretty sure additional filtration isn't going to be an issue, get it. The bio-wheel is really worth its weight in gold.
