Setup

Planning on buying a Corner Flo 125. I've never done a sump tank. This comes with everything you need minus maybe filter media to get started right? If we have a stand, Can we buy the tank and filtration together without a stand? Our LFS has this and we would like to get the tank and sump!
Asked by: Aparker2005
This comes with the tank, and the plumbing for inside the tank. You would need in addition to this, the sump, a utility pump for the sump, and your return plumbing. I can send you via email some plumbing tips that may help you quite a bit, in figuring out what you need, and how to install it. Sumps will not fit in all stands. BREX

I am replacing a 75 gallon tank with a corner overflow tank with a 120 corner overflow tank

I am putting it behind a wall, and building the framing now. I have seen the 120 at our local fish store, and it appears the corner overflows are pretty much the same. Am I correct in this? I am wondering how close the bottom holes will be in the new frame. Also, from what I understand of tank stands, the weight is basically distributed to the outer frame, so can the underneath be open and visible, using 2x4's to evenly distribute the weight along the outer frame? Do you have any links to building a frame for a large tank?
Asked by: SuzyQzz
Yes, they are the same on all tanks, basically. I will email you a CAD drawing in a bit. We are not allowed to give advice on custom stands as they void your warranty for the most part. Instead of a Limited Lifetime Warranty, you will only have a one year warranty on the tank itself. If we were to advise you how to build the stand, and it didn't support the tank right, we could be liable. I will say that a stand must support certain pressure points of the tank. It's not just about the weight. BREX

Plumbing

I purchased a 75 gallon Marineland drilled tank used. The person who sold me the tank gave me the return tube and sump pump pipe without the nuts that secures them to the tank. Where can I pick these up as I cannot locate them on the website?
Asked by: Erik70
These are not available separately. You would need to have a local store special order the overflo plumbing kit for you. It would come with the pipes, nuts, bulkheads, etc. Give us a call, and we can probably pull some from the warehouse for you. BREX

Corner-Flo Circulation

I have the frameless 60g cube with corner-flo. As I look at the overflow box I don't understand how water enters the vents on the lower level and makes it to the top. When the removable piece with the lower vents are installed it has a inner ridge on the top that blocks that entire flow channel. Can you explain this to me? Thanks.
Asked by: Drummond
The narrowing at the top is what helps the flow of water over the draw water from the lower vents. It works on the same principle as those aquarium siphons that you hook up to your faucet. It's not meant to be the same flow rate as the water over the top. BREX

150 gallon 48x24 with 2 corner overflows

I was wondering if you would know if there would be room for a third hole behind the corner overflow for a second overflow for a Siphon system ? And then also what are the outside dimensions of this tank
Asked by: Joshua12
We would not recommend a third hole behind the corner-flo. It would be very close to the corner and could weaken the glass and cause a break. Dimensions are: 48-3/8 x 24-3/8 x 31 BREX

Since I live in the area of Blacksburg, is it possible to buy an aquarium direct from the factory?

I am looking for a 180g and stand.
Asked by: bmg4791
Thank you for your interest in our company. However, we do not have the manufacuring facility in Blacksburg. The tanks are manufactured in Illinois. We also do not sell/ship directly to our consumers especially for our glass tanks. You would need to visit a local family run retailer that would be able to sell you the tank that you are looking for. Sorry, MINI
