Rated 1 out of 5 by from Do not buy !! Asking to get a cloged drain I bought the 150 gallon tank and was told it has a one in half inch drain but really it is a one inch drain !!! Right before the bulk head it has a reducer on it that goes to one inch , Therefor you are not getting enough gph if you want a nice reef tank and asking for something that can fit down the drain to get clouged when it reduces !!! - like snails or a fish that's dead or alive that makes its way over yes unlikely but why take the chance and why do they claim it has a 1 in a half inch drain when they don't

Rated 5 out of 5 by from Awesome tank at an awesome price! I recently purchased the 125g dual corner overflow glass aquarium with black silicone. While I've not installed the tank yet (building a stand), I have to say that the quality of this tank is great. The price was awesome as well especially for a dual corner overflow. The packaging was very good as well. A big, big bonus are the included Durso overflows! Well done Marineland!

how thick is the glass on my 90 gallon tank

Asked by: daddyjdizzle
If you have a standard, Marineland or Perfecto 90 gallon of 48 x 18 x 24, the glass is 10 mm thick in the front and back, and on the sides. The bottom is 6mm thick. BREX

I have the 150 gallons Corner Flo-Aquarium (product # 4749797012) and was wondering how much weight I can put on the bottom glass.

Asked by: Mike13
The general rule is 1.5 to 2 times the gallons for how many pounds you can add. Make sure the weight is well distributed; point contact or impact could be a problem if you are referring to rock.BREX

Is any of the 180rr tempered?  I want to reverse my tank and drill the front due to scratches and remove the corner overflows and replace with smaller overflow.

Asked by: Andrewkw
No, it is not, but any drilling voids all warranty.BREX

Where can I buy the 75gallon to replace the one I got that is leaking, but I want a overflow on the new one? My local petsmart don't sale them, I just want to make sure it fits the stand that came with my 75 gallon marineland tank.

Asked by: pjbaca4
To find a store, simply scroll down the page to the bottom and click on Buying Options. If it is our tank, it is 48 x 18, no matter what and will fit our stands. If you just purchased a tank that is leaking, you need to either the store or us about warranty.BREX

the corner flow piping kit that comes with the tank is already assembled, does that need to be glued together as well or install it as is out of the bag?

Asked by: Pete420
Glue is not needed, install it as is...it is intended to be hand pressed.BREX
