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!

On the 150 gallon tank both the corner overflows and the returns are 1" pvc coming from the sump correct ? Would I keep both the 1" overflows under the stand and Y it into one 1" pipe into the sump?    FYI   "sump is in basement"

Asked by: Jaymon
We appreciate your interest in Marineland aquariums! I will email you the instructions and some plumbing tips we have printed up as they should help tremendously. And yes, they are 1", but we typically recommend one line going to each one; not installing a "y". Your flow rate to each overflow has to be 700-750 gph. BREX

What are your dementions on your 60 gallon, corner Flo pre drilled glass aquarium. And what is the price

Asked by: Mike1984
Thank you for your interest in this product. It is 24"x24"x24". We do not sell directly; you would need to special order it through a local fish store in your area. Pricing will vary.BREX

No, you misunderstood my question about water coming up the return pipe and hitting the inside wall of the overflow. I was referring to the air hole on the return pipe that shoots water against the interior of the overflow. Has that been addressed?

Asked by: Jesse77
I assume you mean the siphon break? No, the siphon break is still in all of our over flows, and is necessary in order to prevent your home from being flooded in the event of a power outage. If you are observing a flushing type of water movement, the issue is in the installation of the pump as the pump is probably not large enough to provide enough head. You can place a piece of filter floss in the siphon break to help eliminate the noise from proper installation.BREX

I am looking for a 5 ft tank app 140 60"-24'-24" with built in overflows. Do you have anything available.One dealer on your list said they could not order a tank for me.I am looking for a tank only.thank you GARY

Asked by: REEF FAN
Thank you for your interest in our tanks, Gary! We have a 135 which is 60 x 24 x 25.5 but it does not contain overflows. Item number is 12160. We do not make one with those dimensions that has overflows as well. You do have to order through a retailer, though, as we do not sell direct. Chain stores cannot order, but definitely locally owned, and independently operated stores can order tanks through their distributors. We have 125 and 150 gallon tanks with overflows, but the dimensions are 72-9/16 x 18-23/32 x 22-1/8 for the 125 and the 150 gallon tanks come in different sizes, 48-3/8 x 24-3/8 x 31, 72-1/2 x 18-5/8 x 26-15/16, and 36" x 36" x 27.BREX
