πŸš€ Abunda's Overview

This is our summary and key points to consider based on customer reviews.


Customers have found their purchase of the tank to be generally satisfactory, with many delighted by its perfect condition upon arrival and ease of setup. It is praised for its comprehensive inclusions for freshwater setups and its suitability as an ideal beginner's reef tank. However, a few users reported incidents of defects such as leaks and chips in the glass, and some expressed concerns about the quality of the filter and lights. The tank is considered beautiful and sturdy, but there are perceived limitations for more advanced aquarists.

Pros

  • πŸ‘ Easy setup and tank is thriving
  • πŸ“¦ Well-packaged and arrives without damage
  • 🐠 Ideal for freshwater tanks and suitable for beginners
  • 🏑 Compact size for those with space limitations

Cons

  • πŸ’§ Some units had pinhole leaks or chipped glass
  • 🧩 Might require additional purchases such as a heater
  • πŸ“ Limited space may restrict fish and coral quantity
  • πŸ’‘ Filter and lights may need upgrades for serious hobbyists

Should I Buy It?

If you're new to the hobby or looking for a compact and easy-to-set-up freshwater tank, this product comes highly recommended. However, if you're an experienced aquarist with plans to expand or delve into more advanced setups, you might quickly outgrow this tank and find yourself looking for upgrades or a larger, more robust system.


  • Beautiful aquarium! Good to beginners!
This is a great product. It is sharp and great quality. The ONLY wish I had was that I had some instruction on how to test the water in the tank to make sure the levels were right for the fish. It made me nervous. Yes, I was more of a novice. So, you should know that it was easy to assemble and the curved sides and lights are gorgeous. I honestly wished I had gone bigger. ... show more

  • Love it!
What to say- I absolutely love this tank. I love how the filter system in back is out of the way and yet easy to get to. Its easy to clean and its made so space is considered in regard to the filter-heads in the middle. I love that its all in one so there is no worries of leaks as you get with some reef systems that have to have a sump below. For a nano-saltwater tank this is just what I needed. Could say the lid is a little hard to get on and off and I wish there was an easy way to do this, however this is a small setback to all the fun and joy this tank is giving. ... show more

  • Packaged well, arrived early
This thing was packaged really well. They could have kicked it off the truck and kicked it up to my door and I think it would have survived without a scratch. It also arrived a week before it was promised. It's a beautiful tank with most of what you need if you're setting up a freshwater tank. All I'm adding is a heater, gravel and treated water. May put another small sponge filter in it down the road so I can bio-seed a second tank when I can convince the wife. This one is to be a moderately planted Gourami tank. The second I think will be a planted Angel tank. ... show more
