Question

New 120 gallon tank, lots of return standpipe noise

We just had a professional setup of your 120 gallon Corner-Flo tank. The water level in the corner overflow fluctuates greatly every few seconds. It goes from nearly the level of the water in the tank, at its highest, to the level of the two side holes in the return standpipe at the lowest. When it reaches the low level, a loud gurgling is heard going through the holes in the PVC return standpipe, as air and water are both rushing in. How does one mitigate this situation?

Try using a "Durso" drainpipe, if there is room in the overflow box. It's simple to make. Glue two 90 degree elbows to the top of the appropriate sized pvc drain pipe so that the second elbow faces the bottom of the tank. Then drill a small hole in the top of the first elbow to allow some air into the drain pipe. It will dramatically reduce both fluctuation of water levels in the box and quiet the draining noise. The only fine tuning required is finding the right height for the drain pipe. I have successfully used them in square overfflow boxes, but am not sure if it will fit in a semi-circular "box". Let me know, because I am looking at a Corner-flo myself.

I had exact same issue, drove me nuts till I figured out that the drain hose going back to the sump was too long and if you create any kind of trap type droop in the drain hose it causes the hose to constantly fill and drain causing fluctuations in the overflow level as well as foaming in the sump and excess noise. I have temporarily wedged the drain hose up against the bottom of the tank to create a more level path for the water to flow and the issues have stopped. I will be PVC hard piping my drain to avoid all future issues. let me know if this helped (make sure you remove any downward droop from the drain)

It's difficult to diagnose the problem without seeing how it's assembled. Is it possible to take photos of how your plumbing is assembled underneath the tank and e-mail them to us? The problem you descibe can be caused by a variety of factors, and is often caused by some sort of restriction in the drain assembly. If you are able to take photos, please send them to: samantha.spidel@unitedpetgroup.com.

Noticed at a store that had a 120 corner-flo that it had black silicone. I asked my LFS to check for me as I wanted to order through him. He called his distributor and according to them the corner-flo tanks all come with black silicone now. I ordered one and am waiting but thought you might want to check and make sure so people have the right info.

Question

drilling out tanks

I am looking for a 125 or 150 gallon aquarium where I can have 2 overflows on 1 end as the tank will be a room divider (one end up against the wall) and I want the front/back/other end to be visually clear. I'm not really wanting the overflows in each back corner. Do your standard tanks have regular glass on the bottom pane that I can have drilled out or do you use tempered glass on the bottom?

Thanks.

The standard 125 and 150 gallon aquariums have tempered bottoms, and they can not be drilled. However, we do offer a custom tank service that would allow you to order the tanks either with non-tempered bottoms, or with the overflow boxes already installed, as you describe above. I would recommend the custom drilling and overflow installation, since this would keep the manufacturer's warranty intact. Drilling or altering the tanks yourself will void the warranty. If you would like to place a custom order, your local fish store can assist you with that process.

I'm not 100% sure what you mean by "reef ready," since this could mean a custom tank, with a variety of drilling and overflow considerations, and possibly non-standard glass. However, our standard 265 gallon tank has 12 mm thick sides and ends, and a 19 mm thick bottom. If you require a different glass thickness for some reason, we may be able to accommodate this as a special order. Your local fish store can assist you with placing a custom order.

Our 125 gallon tank is 72-1/2" x 18-5/8." The Corner-Flo doesn't effect the overall frame dimensions. If the tank is placed on a commerically manufactured aquarium stand (not a custom or home-made stand) there is a limited lifetime warranty on the aquarium. Without a commerically manufactured stand, the warranty period is one-year.

Thank you!

Basically, hook up the intake up to the bulk head designated for the intake (without the siphon break or any plumbing). Then hook up the exhaust to the exhaust bulk head (with the plumbing to ensure that it makes back into the aquarium).

Basically, you follow the set up directions that come with the corner flo, but instead of using a sump you use a canister.

The 1 " bulkhead locations on the bottom of 120XH

I am building a custom in wall setup for the Marineland 120XH (60"x18"26") tank. The tank is special order and it will take 3 weeks to arrive. Can you tell me the grid location on the bottom of the tank where the 1" bulkheads are, two corner-flows (4 holes?) , but I need to know where. I do not what to install the two back support legs where I need to drill the bulkheads through the table. Can you tell me the grid location measures to stay away from? (eg, Something like this: the holes occur at 3'1/8 from the back trim piece of tank at on center a 6"1/4 and 54"1/4" intervals and the second set ...) I can build my table with confidence I an not going to drill a support leg. Thank you!!

Here's a basic estimate. A 90 Gallon would likely lose about the same amount, 3-5 gallons. 48x18x1” of water is about what would drain off the top, which is 3.7 gallons. Then you’d have what would drain out of the overflow box, maybe ½ gallon.

If the plumbing isn’t glued into the bulkheads, there could be a very slow leak into the sump, that could be another 3-4 gallons. Please let me know if you need anything else.

Marineland Corner-Flo Bulkhead Connection Options
Corner-Flo bulkheads for both the return and drain are 1". The threads that are on the outside of the bulkhead fitting are primarily for the nut that holds the bulkhead onto the tank to seal. These threads should not be used to make connections to any sump or other filtration system. 1" schedule 40 pipe can be glued into the inside diameter of the bulkhead fitting. Marineland sumps come with some standard 1” elbows, shown below that are prepped to fit inside these bulkheads. The red arrows point to short lengths of 1” pipe that are already glued in.

With my normal over-flow on my tank i have now, when i lose power, the pump shuts off and no more water can be pushed into the overflow. What happens in this corner-system when the power is cut off? Does all the water that is already in the corners just leak all over my house?

The water will drain into the sump box and stop when it hits the siphon break inside the corner flow. If you have not damaged or removed that feature and followed our set up instructions you should not have to worry about water leaking all over their house. If you have removed the siphon break or overfilled their sump they could have an overflow issue.

Yes, the bottom is tempered. However, when any tank is drilled as a Corner-Flo, we have to use annealed glass in the bottom since you can’t drill tempered glass.
