Marineland has been making aquariums for a long time. They are a large producer of everything from hobbyist grade aquariums on up to commercial live seafood displays. The main advantage to a marineland product, IMHO, is the price. If just a standard tank, it's most likely the system uses standard glass (you could ask if it uses starphire glass on the front) panel, and the most basic features offered. I would say most marineland tanks are the Ford Taurus's of the aquarium world. However, if you're just looking for something cheap and simple, it will probably do the trick. Most Marineland tanks I've seen have cheap plastic bracing around the top edge and use basic overflow systems. I have seen the bracing break and snap on several marineland tanks. Personally, if you're looking for a non-custom, mass produced aquarium, Deep Blue's offerings are a bit nicer, IMHO, for about the same money. They put starphire glass on the front panel of their larger tanks and have a higher quality stand and bracing materials. I have a Deep Blue 90 Cube and 120 gallon that I use as QT tanks. A marineland tank isn't something that I would buy for use as a display, but all of my display tanks I designed myself, drew up the specifications for and had custom built by an acrylic shop that specializes in aquariums. You could probably get a few marineland tanks for the cost of a custom built aquarium.
