Corner-Flo Pre-Drilled Glass Aquariums is rated 3.2 out of 5 by 5.
Rated 5 out of 5 by from Great customer service I bought a 150 gallon with overflows. The store new everything about the tank so that was helpful. I had a small problem with the tank and wrote a review about it. Marine land contacted me and offered to,,, then did take care of my problem. I've since moved to a smaller home but have 3 marine land tanks. Two 75 gallons and a 30 I made into a dump. I will only buy marine land tanks. Except the horse trough that's part of my sump but even then for a few extra dollars I could've bought another 75 gallon that would take less space in my closet.

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!

Is the back panel on the Marineland 150 deep dimension tank tempered glass? Can it be drilled? I am considering a modification. Thank you. 

Asked by: Kent12456
None of the panels are tempered. However, any modification or drilling voids ALL warranty.BREX

Can I get assistance buying the 150XH in Southern California - I've called every lead on the site of shops that allegedly carry Marineland's products; no luck finding someone who can order it. I've never had a more difficult time trying to spend money.

Asked by: KS12345
Good morning, Thank you for your inquiry. We are sorry to hear that you are having trouble finding the tank that you are looking for. Unfortunately, we do not sell our tanks directly to our consumers. Therefore, you would need to find a local family run pet store (mom and pop) and they would be able to order the tank for you. The larger chain stores are not going to be able to order these, as they only carry certain items at their locations.MINI
