The tank is built with a wide variety of uses in mind suitable for reef, marine, salt and freshwater setups. Sea Clear products are known for their exceptional quality which is the main focal point of this particular fish tank over other similar tanks. However, the pricing of this tank is a little higher than other competing tanks such that one would need to decide whether their budget would permit a slightly more expensive spend for the extra quality on offer.

The product also comes with a limited lifetime warranty epitomising just how seriously SeaClear view the quality of their products. This particular acrylic tank is also more suitable for a warmer ecosystem since acrylic has much higher heat retention than glass although some aquatic enthusiasts believe it discolors.

However, MyAquarium’s extensive testing along with consumer comments shows that the SeaClear product in particular does not discolor even after long term use quite possibly due to the quality raw materials SeaClear uses to produce their tanks.

It is a standard rectangular shape with similar dimensions to other 40 gallon tanks and the glass is of high quality.

Further move being acrylic modifications to the tank can easily be made without risking fracturing or damaging the remainder of the tank, note this will void the guarantee.

Clear-For-Life 40 Gal Uniquarium Filtration System

The aquarium doesn’t include lighting or a hood although you can easily add standard sized LED lighting to suit. Being a molded acrylic tank, standing at 36” Long x 15” Wide x 16”, rather than having seamed pieces of glass algae can grow around the edges thus require a little hands on cleaning rather than just using an external magnetic cleaner (not ideal for acrylic either as particles can trap and scrape the material). Many users of the Uniquarium filtration system swap out the bioballs over time with live rubble rock due to over nitration.

This Clear-for-Life Uniquarium is a solid investment for any aquatic fanatic, whether you are getting started and want an all in one tank, looking for a feature piece for your home or a looking to build out a planted / reef aquarium.
