Size: 3-Gallon
I have owned a system 3 for almost 6 years now! If there was 1 word to describe this it would be: Effortless.

This is a fine piece of machinery that looks and runs great, for years to come.


-Change the filter every 1-3 months (depending on the clenliness of your fish and the nuber you have)

-25% water change every time you change the filter or every other time (again, depending on your fish

-I also reccomend a gravel cleaner

-About once every 8 months to a year, I have to clean out the impeller housing to clean out the junk that builds up because of reduced performance.(manual shows step by step instructions on how to do this, and if you loose your manual, go to to download one for free)


none really, but it is quite small. Recently I have been looking at the system 6 or 12.

*I'm not sure about how it would do with salt water, as I have not tried, but reading reviews I have not heard very positive things about that.

*After having it for about 5 years, white crust started to show up on the edged of the tank lip. One more thing to clean, but what can I say? I have nothing to complain about though, because you can look at other 6 year old systems and they would look like junk, where as mine is in perfect condition(except for the little ECLIPSE marking on the front is half worn off from use!)

All in all, I have been happy with this tank from day one and I'm sure will continue to be happy with it for years to come(if I don't upgrade, that is!) and I would definetly reccomend this to anybody wanting a quick to set up, long lasting, all in one machine that looks stylish. I hope this helps!

When I was in middle school, I was an avid tropical fish fan. I raised and bred all sorts of fish from easy to take care of goldfish to more challenging angel fish. That was years ago, but my fascination for tropicals has never really left me. I wanted to start up a small tank with a few fish, just for the fun of it, but without much of the hassle. I saw the Eclipse System package and tried one out. Here are my impressions of the kit.

The whole system is a complete package that contains all the necessary equipment that you'll need to get you started in keeping tropicals as pets. The kit includes the actual tank (which is plexiglass), the pump, filter, hood and light. The gravel and other accessories, you provide. Marineland boasts that the biofilter is able to eliminate much of the toxic buildup that occurs when you keep fish, thus providing a carefree, minimal amount of maintainence. Is it true? Yes and no.

Regardless of which filtration system you use, it takes about a month or more before beneficial bacterial builds up in the tank. These little critters are what is behind keeping the fish wastes under control. I found that the Eclipse system can do this, but only if you are very careful in keeping only a few fish in the tank. (Don't believe the photo on the box which seems to have 15-20 fish in the tank. In real life, they all would be dead if they were crowded this way.)

Added to this, the condition of your tank water is very, very volatile because the tank is so small. Overfeed your fish, or having a fish that is dead and hidden will reek havoc on your tank and most likely kill or make all your fish ill. The magnetic impeller motor can overheat and burn out easily if your water level becomes too low.

Size: 5-Gallon Verified Purchase
I purchased the 5-gallon hex design of the Marineland Eclipse systems, and I've had it up and running for a few months now and overall I'm pretty impressed. I should say that this is not my first tank, in fact this makes 7 (some of my others include a 55 Oscar tank, a 30 gal cichlid, etc, soon setting up a 125gal)! Yup, I've caught MTS (multiple-tank-syndrome) a while back, and its really become much more of a hobby then just something pretty to look at, but that's besides the point.

First, the acrylic means no seams for caulking, which is nice on a piece that has 5 visible joints. There also doesn't seem to be any size distortion when viewing like my glass tanks. However, the acrylic is far more likely to scratch, which means you need a specialized acrylic scrubber and have to be far more gentle when moving items around. This has been up and running for a little over a month, and I've banged a castle decor piece against the sides a few times, but I haven't had any scratches so far (knock on wood, er acrylic, whatever the case may be).

Setup is easy, and surprisingly, this is one of the best beginner kits I've seen, because the documents made a lot more sense then my other kits (most kits are just a bunch of parts thrown in a bigger box and have incredibly short and generic setup guides). However, while I do say anyone can learn and keep aquatic pets, I am hesitant to say everyone SHOULD keep aquatic pets. Even simple fish still require far more care then people realize.

The filter is very quiet, was easy to setup, and seems to do a pretty good job. The parts all seem to be made of fairly good construction.

I'd say the simplest setup for this tank would be a betta, which are incredibly easy-care fish, and a 5-gallon is the perfect size.
