SeaClear 26 Gallon Flat-Back Hexagon

SeaClear 26 Gallon Flat-Back HexagonFor someone who wants a uniquely shaped aquarium without the bent front aquarium, the classy flat-back hexagon style is a fantastic alternative.

Meet the SeaClear aquarium

The hexagon shape makes the tank look bigger and more impressive than a regular flat-fronted tank – without the possibility of visual distortion from a bowfront tank. It is beautiful, striking aesthetic and SUPER strong.

Today, I’m going to show you the ins and outs of this tank, as well as what makes it so special. So, keep on reading to learn more about this gorgeous aquatic showcase!

SeaClear 26 Gallon Summary

Quick stats:

  • Gallons: 26
  • Shape: Flat-Back Hexagon
  • Weight: 20 pounds
  • Dimensions: 36″ x 12″ x 16″
  • Model number: X1010035260
  • Material: Acrylic

There’s no doubt about it: this is a market leading quality aquarium.

You’re getting the best of the best with this tank – made to be totally leak proof with a lifetime warranty and expertly constructed out of crystal clear, thick acrylic.

Also, the makers of the SeaClear aquarium line specialize in designing and installing tanks and have a high reputation for their dedication to customer service. So, the durability and sturdiness in performance of their aquariums does not compromise the aesthetic. It’s a win-win!

  • The tank measures 36″ long x 12″ wide x 16″ tall
  • The access opening at the top of the tank measures 28″ x 5″
  • The acrylic itself is 3/16″ thick on the side walls and 1/4″ thick on the top.

Don’t worry – it’s entirely suitable for either fresh or saltwater hobbyists. The size of this tank makes it large enough to make a significant impression in the room, but not too enormous to swallow up everything around it. It also won’t stick out any further than a 10-gallon tank. The longer shape allows for good horizontal swimming room side to side for your tank’s inhabitants.

Back Panel Style Options

You get 3 back panel styles to choose from with the SeaClear 26 gallon:

  1. Cobalt blue is colorful, and the fish and plants really pop.  It is also popular option among reefers.
  2. Black is striking and classic and is great for concealing equipment behind the tank.
  3. Clear affords a 360-degree view of the whole tank. It is a crisp, clean look unto itself. You also have the flexibility of adding a static cling background which can be changed out as you like.

Which is best? It’s totally up to your personal preference.

Having both blue-backed and clear-backed SeaClear fish tanks, I can definitely say each has their own set of advantages. When it comes to freshwater aquascaping, clear (backless) seems to be the predominant trend. But if functionality is your object, opaque can be useful for hiding filters, cords, and other unsightly objects.

Acrylic’s Advantages over Glass Aquaria

Yes, it is true that glass tanks don’t scratch as easily as acrylic ones (although most scratches can be buffed out on an acrylic surface). And they’re usually cheaper. But acrylic has some tricks up its sleeve.

For starters, it’s 10-20 times stronger than its rival material. It can withstand chipping cracking and shattering much better, which can be especially useful if you live in an area prone to earthquakes or plan to locate your aquarium in an area with higher foot traffic.

And to take a load off your back (and arms and feet), it’s also way easier to lift due to the lightweight nature of the material. As in, less than half the weight. So, most people can actually pick this tank up by themselves without too much trouble.

Get this: SeaClear’s acrylic tanks are totally leak-proof! There are no seams that have to be siliconed together like with a glass tank – it’s all constructed out of one solid piece. The larger the aquarium, the bigger the problem it’s going to be if there’s ever a leak or a crack. So, you can have peace of mind knowing you won’t have to deal with the problem of a leak as the silicone gets damaged. Pretty nice, right?

Did I mention that these acrylic aquariums are rimless? Meaning, you don’t have to deal with that unsightly, distracting black/wood trim that’s used on standard glass tanks to brace the weight of the water. This is a huge plus for those who love beautiful aquariums with a focus on what’s inside it rather than what’s around it.

This is interesting: One thing fishkeepers have noticed is that acrylic fish tanks seem to be able to hold a more stable temperature than glass tanks, which is just the icing on the cake, as you can see.

Also, acrylic gives you a better view of what’s inside your aquarium. It’s significantly brighter and clearer than standard glass, since regular glass tanks have a greenish tint that darkens the view due to more iron particles being in impure glass. That means you have to specifically buy a low-iron glass aquarium if you want to achieve the same clarity and vivid view as an acrylic tank.

So, with so many amazing benefits of acrylic, it’s no wonder why so many fishkeepers are transitioning over to this as the material of choice for their fish tanks.

Selecting the Right Stand for Your SeaClear

So, you’ve found the tank of your dreams. But the next logical question that comes to mind is, what are you going to place it on?

Good news: Finding the right stand shouldn’t be too much of a challenge for this piece – any regular rectangular stand will do, provided it is at least 36″ long by 12″ wide.

But here’s the catch: It really should be a solid top, cabinet-style stand, as this tank’s bottom won’t touch all edges on a frame-style stand due to the more unusual hexagon footprint. You can find them new on Amazon, your local pet store, or even used at a secondhand shop.

All set? After you get yourself a good stand, you should be ready to start setting up your new tank!wave tropical divider
