Don’t buy this tank for saltwater. Saltwater is simply not this easy. You won’t find Nemo here. Do the research. Read about the nitrate cycle, evaporation in saltwater systems, etc.

We received this tank as part of a class on marine tanks and the teacher provided a clownfish, small coral, and a live rock to go with the tank. So far the tank is the perfect “see if you are interested” tank setup for a beginner. We do 1 gallon water change per week with top offs. The tank is super low maintenance and even our friends who are experienced marine tank owners were really impressed with this as an intro setup and the lighting. We are planning on upgrading to a 20 gallon when our clown is bigger, but for now he is so tiny and would be lost in a big tank and who needs the inconvenience of more supplies used when not necessary. Hope to have this tank for a year or so—will see how quickly the fish grows, but it will give us opportunity to research and get experience on a low risk, cheaper tank first.

Great nano aquarium for saltwater. Good for corals and simple set up. Great AIO system

I did a lot of research prior to purchasing a tank and what was needed to properly care for a Betta Fish. I bought this tank off of seeing great reviews of Fluval. Initially, the tank is very easy to setup and is also very easy to decorate as it has a decent amount of space. I let the tank run approx. 3-4 weeks before adding my betta fish to the tank which was fine, no issues. After awhile, naturally the algae started to grow so I decided to add shrimp first and then a snail. The biggest issue with this tank is the filter and the horizontal slit that is in the lower portion of the tank. It sucked up all of the shrimp and my snail one time. The shrimp died, however, I was able to save the snail in time. The filter does an alright job but does need to be replaced quite frequently. I am now experiencing cloudy water which will not go away even with a water additive. I plan on getting a new tank due to these aforementioned problems. If you plan on just getting a fish with no other life in the water, this tank will probably work alright, but I feel there are better options. Will still continue to use Fluval products besides this tank. DO YOUR RESEARCH BEFORE STARTING AN AQUARIAM.

Bought this close to 6 months ago at least. Switched from an old back tank filter. This fluval tank is beautiful! But I’ve struggled with cloudy water and algae build up since day one! I’ve tried just about everything but at this point I’m having to clean the tank weekly and stressing out my poor little fish. Gone so far as to remove all plants, and severely cut down on feedings. I’m to the point I will concede and buy a back tank filter which will make the lid useless. Had high hopes for this tank.

Just set it up, so not sure about how I will feel a few months from now. Beautiful tank, but lid came with crack, (almost expected as the plastic lid is very thin and packed below the tank), not worth sending back because I feel I will replace it anyway. Not a fan of the opening mid lid right under light. Feel the tank needs a clear full lid, maybe heavy plexiglass if not glass to avoid evaporation. Like that the motor, etc is hidden. Time will tell if the motor which appears small will be enough to move enough water through the filter to keep the tank clean. Light for now seems it will be bright enough for my guys, fan worms, non-photosynthetic corals, porcelain crabs and the pods I replenish every so often that keeps them happy.

Great budget all in one tank. Will need to upgrade the return pump and light but overall a great value

I’ve had this tank for about 1 - 2 years now and about half a year ago I got a small clownfish. Today I woke up to it being stuck in the filter tail first. He was healthy and had no problems and the body even doesn’t look that bad, but he is dead. I usually wouldn’t have a problem with this but since this is marketed as a nano tank where small fish are the norm, why would a small fish be able to get stuck and die in the filter? Besides that it’s a great tank and if you can control the algae ( I haven’t had too much since a first algae bloom ) it can be pretty easy to take care of.
