HOW TO: Build an aquarium overflow weir 

U are the man !!! Im upgrading to a 150 from a 90 gallon african cichlid tank and I can't decide whether to run a sump or 2 fx6 filters , but with every 1 of your video's I watch I'm leaning towards a sump , I most definitely love ur channel. Hands down the best channel on youtube for fish keeping

Just wanted to say thank u for your cost saving & simple alternatives to paying retail for essentials or upgraded options. Its a great benefit to lots of folks that probably never think to say thank you

Nice! Love the slightly longer videos! Never thought about using a bucket for overflows and filters and its a great plan! Thank you!

YOURE THE BEST! When I watched your internal sump video last week, I was thinking "Man, I wish he did one with a weir". Thank you so much for this incredibly useful information!!!

Hi I am looking to make one like this and wanted to ask Can't we just make teeth on upper section of the pipe and use a taller pipe Thereby removing the need for wier.

Awesome video! So practical. Yet another idea that I'll be implementing into my fish room soon! Thanks Joey

Short and to the point. Pretty sure I'll be attempting this one soon but that massive canister filter's pretty cool too!

I recently bought your book. I havent really read to much of it just yet, but the parts that I did read were great. I have seen what feels like close to all of your videos. While I read the book my mind puts the words into your voice as if I was watching one of your videos, its kinda creepy sounding but I cant get it out of my head... keep up the great videos!!

Thanks for the great explanation Joey! I have to set one of these up on my 210 so this was VERY informative.

like the way you show how to undone the hole, simple & easy.

nice vid :-) i would like to see the "Do a diy hang on back overflow box" down to a sump. Regards :-)

another great video! now we need more podcasts!

Do a diy hang on back overflow box

I always wanted to see a video like this!by that I mean..something helpful and useful. Good job.👍😊

Great information. This helped me better understand my built in wier on my 92 gallon corner tank. Thanks

I just purchased your book. love the channel. Your awesome.

More ideas for me to use in the future. Thanks Joey

Would it be too loud if left as-is? or would converting the stand pipe to a Durso be better? Thanks for the great video.

I got a lot out of this video. What is your opinion on just including the foam with the weir? any detriment?

Got the book, love the book. Would recommend 10/10

Lots of great info in that video, thanks very much.

hey can you make video all about the Arowana ? filtration,care,food timing whatever you can possibly cover in video ?

joey I have been trying to decide how to build and design my sump for my 135 gal. it will be freshwater cichlid tank more than likely. I want to do an overflow box to hide everything but didn't know if I could use the diy pvc overflow pipe behind this or would it not work. I like your pvc weir overflow as well

Hey Joey, What you are doing for the community is great. My question on this build is that, after the weir is added to the build, do we still need the stand pipe? I am simply not able to understand the use of stand pipe once weir came on.

Joey, as I am not a native english speaker, I didn't understand one important thing: A 1x0.5 inch tooth will flow 50 or 15 gallons of water? Thanks in advance!

I just see it as more work than required and a permanently modified tank. Plus takes up room in the tank. I made a diy 12 gal sump from a cooler and some spare odds and ends for my 55 gal. . Instead on drilling for the tank output or using a pump for the tank output to the sump. I used large hose black garden hose for both input and output to the sump. Then clear hose from behind the tank down into the tank. The output from the tank to sump has a 16 oz clear water bottle screen with filter around it so fish are safe and can’t be sucked in. From tank to sump is siphon powered and is made to where if the power goes out the water level in the tank can’t drop more than a couple inches nothing can overflow . And from the sump to the tank is a pump I modded to accept the garden hose The end result is simple easy to make takes up very little room and Doesn’t require any sort of modifications to the tank. And it’s whisper quite.

Hey joey. This is an old video. I just started watching your channel. Really cool! Now you are a super star. :) But, Can you cover the Wier with a two part black epoxy? Is is safe for fish?

I'd be interested in a video with the same weir for non drilled tanks what's option do we have?

is there a practical advantage to cutting up a bucket vs just siliconing a straight sheet of acrylic to a corner?

Hey Joey, Looks like a DIY Reef Tank?! The Bucket idea is great, nice one!

Love your videos. What is the smallest tank that you would use an overflow and sump?

Have you ever build a diy magnetic mounts for power heads that come with suction cup mounts,or could you show us a way to do that? Please and thank you

great video Joey keep up the good work!!

Joey you are the man !!! Thank you brother.

Hey Joey, big fan and watch all the vids, even considering Facebook just to be able to keep up with you... I've always wondered if it's possible to run a system with a small display tank and a huge sump, gives you the water volume but your display tank can be any desired size?

How effective would the sump design be in filtering bottom of aquarium if the water at top of tank is the only thing that would enter the sump? Is this where power heads come into play to get the bottom water circulating?

Could this also work as an internal filter? Say with some filter floss at the top, a bag or 2 of lava rock in the middle and a powerhead at the very bottom?

as always Joey, Great video!

is it possible to use acrylic and silicone to seal the glass hole that holds about 2 gallons of water? I ask because I will need to remove it in the future and glass on glass will be impossible for me to detatch with my weir setup.

All that depends on the flow capability down to the sump being quite a bit greater than the flow up from the sump pumps. When the flow down is getting marginal - you'll first lose all skimming.. the weir water level will equal the tank water level.. because the increased head pressure in the tank forces the pump flow rate down the overflow/standpipe. For a 1.25" schedule 40 durso style overflow - that is about 600 GPH. 625 max

Thank you so much. I've always wondered if i could convert my overflow tank to a non one.

Extremely helpful video! Cheers

what are your thoughts of using bottom section of the bucket and drilling your back glass so its just in the top corner of the tank not all the way down

Thank you very much brother... Instead of drilling hole we can use Diy Overflow using PVC pipes (available in youtube)...

All your videos show a bottom drilled tank with a stand pipe. Is there a specific advantage of a bottom drilled tank? Why not just drill at the back at the required height?

Thanks for sharing Joey?

Sorry if I missed it talked about already but, it seems like a lot of unused aquarium volume. I could see how the foam could interfere. Is there any other way to use that I volume as filtration. Or is there are enough circulation for heater.

what type of system should I run on a 40 g long tank to get lateral flow and more importantly better filtration 1 ft tall and 1 ft deep 48 1/2 width please help me out

How long does the Krylon Fusion paint last and doesn't it flake off after awhile?

what are the advantages of this over a regular pump filter?

All this work when you can just simply put the hole near the top edge of tue aquarium. Lmao

Are there any other decent DIY options other than a bucket?

Thanks for the info, Joey.

Great video very informative!

Is it possible to add a weir to an already established aquarium?

awesome!! great information.

man...great video!!!

hi joey. intake or overflow system is the best in a 4ft tank?????????

How would you go about filtering out any particles as they wont get over the weir to the sump.

dude, im still not getting the good flow rate..., the only thing that's different is that I added a quick disconnect BELOW the tank. Would that be an issue?

this paint is safe for fish? which kind of paint is it?

Nice vid joey

So if I needed it to flow at say 300 gph, I would calculate how many teeth I need and the size, then double them?

Does the water at the bottom of the inside of the weir get stale ?

you are the best

Shouldn't the video be called a weir'd aquarium overflow. Love you explanations. Great job!

I know this is an old video, but, could I use this idea to feed a sump, if so how

what's better bulkhead or universal seal???

hi, what paint are you using?

But what about the stuff that sinks to the bottom? Like if it doesn't catch it at the top it's just going to sink to the bottom

I love this video

In todays video we focus on how to build an aquarium overflow weir so you can ad sump filtration to your aquarium. Get the ultimate DIY aquarium book ► thekingofdiy.com Follow me ► facebook.com/uarujoey

Joey dude any chance you could be even more of legend and do a video on building a "twinstar" electrolysis type algae killer the company charge killer prices on these units there are builds on here but English is rarity in them man,if any one can teach me you can bud

How do you know it is safe paint to use in aquarium?

what measures are the aquarium?

What kind of bit but did he use to drill that hole?

Can i also drill on the bottom of the pvc pipe

i need some help, my overflow is a square and is extremely loud

Joey, I have the book, is there a way that I can send it to you for an autograph ?

how long u wait to care?

Do I have to drill out my tank to do this?

IDK what silicon he used but the ones generally used for glass does not bond with PVC/plastic!

Thank you.

I should just buy your book

ok now combined the 2 make a filter like the weir in the top down through the media and out of the pump

this seems kinda flimsy for the application I would need it for. 150 gallon center drilled. 30" tall tank

thanks for it

How much your book...

does this work for glass aquarium 2

Joey - your link "thekingofdiy.com" isn't working...

wouldn't it be easier to use a blk bucket?? i do like idea though.

how many fish you have???

Fired Up Overflow!!!

running regular carbon filters and air stones fresh water chiclid tank

U r good bro .

👌🏻

could i drill holes instead of having teeth

My tank said tempered glass, do not drill. Does this mean I cant or do they all say this.

I never really trust silicone to stick plastic.

Why didn't u just make some hole on the pipe? That shoul be aesier n more aestetik 😀
