Beautiful and versatile, frameless cubes are compatible with Marineland LED and fluorescent lighting, hang on tank filters, and canister filters.

Rated 4 out of 5 by from Awesome tank I've had this tank for 6 months and love except like everyone else the clips broke on me.

Rated 5 out of 5 by from My 28 gallon I have the 28 gallon tank with stand light and glass cover. I love my tank as much as my 180 gallon I had in the 90s. This 28 provides a depth of field that gives you the feeling of a piece of a river being in my living room. I am now seeking another tank setup and I want the same tank. The box store that sold this tank never seems to carry these tanks normally. Finding this tank is like looking for wild caught white clouds.

Rated 4 out of 5 by from Broken clips My 60 cube tank is 8mo old and I really love it, but I have the same issue as everybodyThree glass clips already broken.

Rated 4 out of 5 by from The tank is fabulous! The clips break if you look at them too hard. It's an easter egg hunt to find the right ones and they are around 15-20 bucks for 4 of them. :(

Rated 3 out of 5 by from Great tank, bad lid clips and stand I got this tank in Oct 2014 for my birthday. The tank is great. The lid clips though are not. I've had two break within a week and I am down to 4 holding a very heavy lid. The stand is also very cheap and the is any water sits on the sill for longer than a few minutes, the finish bubbles. Its not water resistant at all. I wish I would have bought another tank from a different manufacturer.

Rated 5 out of 5 by from We have had our 25 gallon tank now 8 months and love it. We have had so many people walk in and see our tank for the first time and get awed by it. Family and friends who come over often still comment on it and the whole family loves it. Particularly the grandkids. We find a lot of tranquility in it. We much prefer it over the previous one with the metal frame.One problem, but not such a problem. "Canopy Clips." I called customer service, told them which tank and size and they are sending out new clips free of charge. I thought that was pretty cool and I don't have to go out looking for some.

Rated 4 out of 5 by from Did you guys find a place to order a bag of clips from? Down to only 2 clips I need to find someone to buy a bag from unless a better solution is out there.

Rated 3 out of 5 by from Measurements are incorrect The stated measurements on this website are incorrect. I recently purchased the 25g, 45g & 60g rimless tanks.The 18" x 18" x 18" Frameless Cube is 19" tallThe 24" x 24" x 18" Frameless Cube is 19" tallThe 24" x 24" x 24" Frameless Cube is 25" tallI built stands so that the top rims would all be at the same height off the floor. I then built 3 smaller rimless aquariums to go between them aiming to have all of the rims be the same height off the floor.Much to my surprise when I put the small cubes on their stands they were all 1" shorter than the three Marineland tanks.Don't believe the measurements of the Marineland rimless tanks because they are not accurate measurements.

hi, does marineland still sell the 37 gallon cube 18x20x25? if so, i am having a difficult time finding a place that sells it; are you able to tell me where you supply to or how i can get one? or would it be a special order by a pet store that can get it?

Asked by: kittykat
Hi kittykat! Yes, we do still make this tank. It is 11371, and you will most likely need to give that number to a local fish store and have them order it for you. This is not a commonly stocked size. BREX

I have the 93 gallon cube, I need to replace the sump. Is it possible to order a new overflow/bulkhead kit? Also, what is a good sump and skimmer for this unusually sized compartment?

Asked by: Dcf9255
Unfortunately, no, we do not sell those separately. In regards to a sump, as we do not make one, we cannot recommend one. We do recommend our Seaclone 100 Protein Skimmer for that part of your question. BREX

Where can I find a lid for this tank? The measurements are 18 3/4 by 16 3/4 inside to inside.. Thank you 

Asked by: Jbird
Sounds like it is the 18 x 18 x 18 25 gallon cube. Item number for the canopy is NV33018. You would need to order it through a locally owned and operated pet or fish store. You can locate one via our Buying Options tab. Simply enter your zip code into the dealer locator on that page. BREX
