Deep Dimension Corner-Flo Glass Aquariums is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Absolutely in love I bought the 200 gallon Deep Dimensions aquarium on Dec 20, 2014. It was easy to setup and looks gorgeous. The only issue that I have is with the stand. It doesn't have much room as far as height is concerned. I had to go with a compact in sump protein skimmer. If you have the room available behind the tank, you could do an external protein skimmer. Keeping all of the equipment hidden was a big deal for me. It looks nice and clean that way. Everything is built very well. I am in love with my new aquarium and would definitely recommend it to everyone.

Rated 5 out of 5 by from Not to big not to small, easy set up and the ultra clear glass makes a REALLY good looking tank with or with out fish. I have the 150 Gallon deep. It is a fantastic tank because of the depth. I think it works better for both viewing and aquascaping. There is just so much more you can do with multi level when you have the depth to do it. I was going to go with a 90 but when I saw this deep 150 Gallon, I knew this was the not to big not to small size. They use the ultra clear glass which makes a HUGE difference, so you don't have the green haze you just get use to with other tanks. Corner-Flo is great easy to set up and quite. I would do this tank over the 120 just because it is a bit taller and when you view the tank you see fish vs fish and the top edge of the tank. The deep tank is the way to go for many reasons.

Can you take the front panel off the filter tower?

Asked by: Jenn St P
There is a portion of it that slides out, but you cannot remove the entire panel, no. This can cause issue with the structure of the tank as you would need to pull pretty hard, which can weaken the silicone. Any alteration of the tank will also void the warranty completely. BREX

Can I order a 300 DD WITHOUT overflows? Just the tank? If so, how do I go about doing this?

Asked by: Bandit8711
We really appreciate your interest in this Marineland aquarium! Unfortunately, we do not take custom orders any longer. We used to make this tank without overflows, but the majority of people who buy such large aquariums are reef hobbyists, and they prefer tanks with overflows. Therefore, we had to discontinue that model. You might try searching for a used one, however, if you live in a fairly populated area. BREX

I have heard they split seams and leak ? Has this been fixed

Asked by: Carly356
We appreciate your interest in Marineland products! Any aquarium can crack or have a silicone issue at any time. The main cause of such issues is placement of the tank on something other than a properly sized manufactured aquarium stand, improper or rough handling, and improper storage. If anyone has an issue at any time with any of our tanks, there is a Limited Lifetime Warranty on them, as long as they have followed the set up instructions correctly. BREX

The overflow and return assemblies are both taller than My 150, should I cut them shorter, or should they stick out the top of the tank?? Sorry if this is a dumb question, I'm new to this.

Asked by: New2this
Hi New2this, there is no dumb question! It's only dumb if you don't ask it! I think you should send us a picture directly to Neither of them should stick up above the tank, we don't build them that way, and I think it best we see what you are seeing to make sure we advise you correctly. You may also contact us directly at 1-800-322-1266. BREX
