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 4 out of 5 by from Great tank But they stop making the corner flo on the back of the tank which is a problem for me so I may have to go with AQueno tank

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!

Working with my local fish store to get a 180 dual overflow and Monterey stand, both oak color. The online literature shows the 180 tank only comes in black but the store said they can get oak. Does the tank come in oak?

Asked by: Ddad
No, it does not. Additionally, the oak Monterey is a dark reddish oak, not a golden color, like you might be thinking, and the tanks that do come in oak, are more golden. The black tank would look better on the Monterey.BREX

the corner flo plumbing do you use purple prime to mount the pvc pipes

Asked by: Keyland
We do not prime or glue any of our Corner-Flo pipes. We leave that up to the customer, if they so desire.I will send you a document with plumbing tips.In general, since our Corner-Flo Plumbing may need cleaning over time, we don’t suggest gluing the interior plumbing at all.The one connection to the Corner-Flo plumbing that needs to seal is the one to the slip connection on the inner diameter of the bulkhead under the tank. Then any other connections that lead to a sump or filter, must be sealed in some way.The purple primer is simply to help people know where they’ve applied primer. There’s also clear primer and as long as you ensure you have contacted the perimeter of the surface of any fittings, then it is fine.BREX

In your 120 XH dual corner-flo aquariums it states that the maximum flow rate for them is 700 gallons per hour. Is that 700 gallons per hour a total of both of the corner-flos - or is that 700 gallons per hour per each corner-flo? Thanks!

Asked by: Greg1
That is 700 gallons (and they can go up to 750 gph) for EACH overflow, not combined.BREX
