Has Anyone Ever Had A Tank With A Corner Overflow?

Hey All,

Has anyone ever used a tank with a corner overflow for freshwater? I'm not even sure what they're for to be honest.

 

Ive got 2 in my 150

What are they for? I haven't got the first clue as to what they're for.

 

Geez smaurer3076 , you don't know what a corner overflow is and you call yourself a fish keeper? Don't feel bad, I don't know what one is either and I'm looking forward to someone explaining.

Generally they're to run the water into a sump.

And now you're going to ask what a sump is...It's a separate tank usually under the main tank that you can put filtration media, heaters, refugium etc in. Just google it.

Haha jdhef I'm recently branching out in the aquarium world! For the longest time I had the run of the mill, easy 35 gallon. Now I'm going much bigger and I'm excited!

TwoHedWlf Thank you for explaining! Is it a necessary thing to use? Because I was going to use 2 HOB filters for the tank.

 

Sump isn't necessary, it's just much better.

 

So I could

So I could probably just plug it up and go from there if I don't want to use it?

 

I'm assuming you have a tank with corner overflowws?

I highly recommend using a sump if your tank is already equipped to do so. Any of my larger tanks I have a sump on and any bigger tanks I plan for later will be built for use of a sump.

A sump increases total water volume allowing parameter swings to be a lot less dramatic. It allows one to hide any equipment such as heaters, thermometers, refuges, deep sand beds, and all media. It also allows much easier access for maintence. The benefits out way cons which are few. Extra weight, takes up more space, expensive (depending on design). DIY sumps cost as much as over priced canisters. My sump cost me around 200 maybe 250 tops. Pump and tank are most expensive part, but that's why petco has the dpg sale.

I'm a fish keeper and I never heard of a corner overflow before.

Most overflows are in the corners

Oh, you mean the overflow tube at the HOB filter?

 

No overflow box is the right term but most are in corners or in the middle. Some are even dead center. The overflow box is acrylic or glass panels that create a seperation from main tank allowing water to filter to sump under or beside tank. It normally hides stand pipes or just the holes for plumbing. It also helps to prevent inhabitants from entering filtration system.

 

It has the same purpose as the tube on an hob filter. it brings the water into the filtration system. If you have a big tank you should consider using a sump system. You can find plenty of information online. The advantage is a sump gives more water volume and it makes water changes easier

I'm giving Sump filters a whirl, I've never used one but I'm trying it!

 

If you need help just ask. Ive built a few of them and all from scratch. Ive never liked the sumps that are basically plug and play. The options are endless. Researching online is a good start but you won't find much in freshwater. Its mostly salt water sumps that pop up most during research.

That's what I figured.

There's not really much fundamentally different between saltwater and freshwater sumps. More mechanical and biological filtration in the Freshwater one, no skimmers and other marine gear. Less worries about microbubbles.
