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

How do you get the water to draw through the bottom holes in overflow chamber?

Asked by: Jbero
Your water level has to be to the top of the tank. It is pulled up by a siphon/pressure type of action, very slowly. BREX

Are the "corner-flo pre-drilled" tanks appropriate for freshwater tanks or only saltwater/reef tanks? Thanks.

i was just wondering how much it would cost for either the black 75 gallon tank or the oak 75 gallon and also would it be possible to order one with two corner flows one on each side thanks

Asked by: Austinv
We do not sell direct. Additionally, we do not make custom tanks. The 75 gallon tanks come with one overflow only. Average retail cost for a 75 gallon with stand, canopy, etc, is approximately $600+. BREX

I have a 120 gallon dual overflow marineland deep dimensions tank. It measures 60" wide x 18" deep and 22" tall I believe,  I have ano eshopps rs300 sump , what do you recommend for a return pump? Thanks 

Asked by: Mgh323
That would not be a Deep Dimension tanks, as those tanks are all 36" deep. Our 120 is 60 x 18 x 25 also, so I'm not sure which tank you own. However, all of our corner overflows require 750 gph at the top of the overflow. BREX

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!

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