SeaClear 50 Gallon Aquarium Summary

seaclear 50 gallon

Check Price

Quick stats:

  • Gallons: 50
  • Shape: Rectangle
  • Weight: 20 pounds
  • Dimensions: 36 x 15 x 20″
  • Model number: X1010012500
  • Material: Acrylic

The 50 gallon rectangular has sleek curved corner design for seamless front edges.

I think you’ll agree with me that they are quite beautiful…

And of course, the entire aquarium itself is totally rimless.

This gives the tank an exceptionally high-end look and feel, putting the focus on the fish and plants (what’s inside rather than what’s around it!).

Rectangular aquariums, like this one, are also ideal for fish that enjoy more horizontal swimming area.


  • The tank itself measures 36″ long x 15″ wide x 20″ high
  • The access opening on top is 28″ by 7″

The thickness of the acrylic is 1/4″ and very durable.

It’s also suitable for freshwater or marine use.

So, what’s this about the access opening?

Great question.

The SeaClear 50 gal acrylic aquarium has a partial edge around the top perimeter of the aquarium.

Because the tank is rimless, this helps to protect against spills in case it gets bumped on accident…

… While allowing you the capability you need to interact inside for decorating, maintenance, etc.


You just might find this ledge is quite nice for resting your arm on when it gets tired during a water change.

Back Options

You can choose from 3 built-in background colors for your SeaClear rectangular 50 gallon aquarium: clear, black or cobalt blue.

The cobalt blue is especially popular among reef enthusiasts.

Clear is probably the most versatile, as you can always put stick-on background behind the tank and change it out whenever you wish (or just leave it clear, which looks very beautiful).

The opaque black or blue are nice in that you don’t have to deal with applying backgrounds to help hide your equipment.

If you ever change your mind down the road, you can always use a flexible internal aquarium background such as 3D rock or even a custom cut sheet of acrylic in your color of choice.

I found it’s also a nice option to replace my blue background of my SeaClear rectangular tank with a sheet of 1/8″ solid white acrylic, which looks very sharp and is easy to manipulate in order to get it inside the tank.

You can use silicone to fix it in place or prop it up with decorations for a less permanent method.

Lid Suggestions

The tank comes with a black light fixture that is supposed to double as a lid.

Many fishkeepers (including myself) opt to replace this with a nicer light fixture, which does away with the hood.


Since the tank is partially enclosed, you may find there is no need to have a lid.

Unless you have fish that would jump out of the tank.

Otherwise, you may opt to get a piece of glass or acrylic cut at your local hardware store to fit the top of your SeaClear’s access opening.

I have found it is very easy to slide it over when it comes time for feeding.

Why Choose Acrylic Aquariums over Glass?

There’s no doubt about it:

Acrylic poses some serious advantages in aquarium applications than traditional glass tanks.

It may be more expensive, but you get quite a few benefits in exchange.

Such as…

1. Safer

Another major advantage of this tank?

Leak protection!

It’s built out of one solid, melted piece of acrylic so there are no seams – like there are with glass tanks.

(Those seams are usually what end up leaking.)

Many fishkeepers find themselves frustrated over and over again when they buy a new glass tank… only to have it leak.

Not only is this dangerous to your fish (especially if the tank leaks overnight when nobody is around to intervene), it’s a great way to damage the surroundings of your home or office.

You’ll appreciate having the greater peace of mind.

2. Clearer

One thing you’ll notice right off the bat when you see this tank in person…

… The acrylic on this tank is CRYSTAL CLEAR – significantly brighter than a standard glass aquarium.

This means it’s better for viewing your aquarium’s inhabitants.

Colors of the fish and plants just pop!

3. Stronger

It’s super sturdy!

Acrylic is 17 times stronger than glass, being able to withstand cracking and chipping much better.

Whether you live in an area prone to earthquakes or one with small children or dogs running around, the nightmare of having your tank start crack will be one less worry on your mind.

4. Lighter

You’ll be shocked at how lightweight this tank is compared to a glass one.

It’s also waaaay easier to move around.

Your back will thank you!

Suitable Stand Options

With tanks 50 gallons and over, you’re really going to want a sturdy stand to prevent the tank from wobbling over every little thing.

Cabinet-style stands are a good solution, or a frame style one that’s got lots of support.

The dimensions on this tank can make it a little trickier to find an appropriate stand size, as its has a different footprint – slightly narrower – than the average 50 gallon aquarium (which helps it take up less space).

The good news is with a cabinet-style stand such as this one it’s okay if there’s a little extra front-to-back room on the piece.

(Not so with a frame-style stand.)

Some folks opt to paint their stands once they find the one they really love, if it comes in a color they aren’t as fond of.
