Viewer Request Video - No Drill Over Flow 

I've been thinking about this idea for about a month. I don't have the material, tools, or need to build one right now. However I was thinking about running a small hydroponic vegetable garden linked to a fish tank... And of course somebody's already thought of and created this overflow device. It's elegant and even solves one of the problems I hadn't figured out yet. I'm always slightly disappointed and also rather excited every time I come up with something only to find somebody's already made a better version of it.

Good video. Some people attach the air hose to a power head in the sump to keep the vacuum or restart the psiphon when the power comes back on. I am sure you know this is for other readers

A work of art!!! It's always easier to use "talking paper" to explain things.

I can listen to you all day. Very good key points made about how this works And why it’s important to get specs close as possible for effective use. Nice drawing and building with the voice over. Best teacher. Take care my friend.

Awesome! It's just easier to drill the hole, fit a drain pipe into it, and attach the drain hose! Personally, either way, I would wrap some screening around the intake to the HOB overflow to keep my fish from being pulled out the same way I wrap the intakes of my HOB filters... Especially if you have fry and/or very small fish! Great Build, Though!!! :-)

Dude your projects are so easy to follow.

Awesome!!! Love the design! Thanks!!! I will post when I get one up and working!!!

Travels through the RU-vid, right onto my iPad screen.😉

Another masterpiece my friend

Hi could you tell me what thickness should I use to make a flat tank lid.i made a lid for my betta tank out of 5mm acrylic and it keeps bowing I've tried to brace it but it still bows. by the way another wicked build.john UK.

Awesome, I really enjoy your projects!

Thank you!

tks for the great build. wondering if you extend the inside box to touch the bottom of the tank and flip your drainage grate to the bottom, top of the box flush with the top of the tank, outside box the same; will this act as a vacuum system to pull debris off the floor of the tank? maybe one or two slots in the top to act as a skimmer then the rest of the flow through the bottom. will this work? or will it just overflow the tank?

Great! So all I need is a youtube! And an aquarium. 😃👍

What I can't get an answer on, mainly because most people use these inside overflow boxes, is what happens if you just drill a hole an inch from the top of the aquarium and attach the bulk head and hose down to the sump and a screen inside the aquarium to prevent the fish from passing through. The return from the sump (above the water line to prevent back flows) would fill the tank and push more water down to the sump. The simplest system as I envision it and no ugly box inside the aquarium. Is it a noise issue? Or am I not accounting for something?

Have you made a through the glass one that you’d drill the tank? I’d love to see if you have made one.

Awesome 👍👌👊🙋

Let me congratulate you for 10K Right Now!!!!………..what's a few weeks :)

Hi . I need your help. Which dimension of the u-tubes should I use if I’m using a 6500l/h pump. Thx

I want like 6 of these!

if you don't have an mill machine, (most people don't) you can cut the slots with a router table! better then a table saw.

Sir excellent job

Very cool. I'm trying to understand the risk if you get air into the "U" pipe. I'm thinking if enough gets in the siphon is broke and you would have a tank overflow?

First :D Very cool video have to say. Would be cheaper to make it out of PVC, but for demonstration purposes that overflow system looks pretty cool. Could add flake food to demonstrate the rate of flow :)

Great video ... I thought the airline idea was brilliant.

Wonderful.thank you. Is that chloroform using for fixing/gluing?

Cool design Fishman 💪

Awesome stuff. What's the gluing solvent you use? DCM? MEK? Cheers!

My issue with drilling is I have 4 10 gallon tanks and from what I hear drilling 10 gallon tanks is a nightmare because of how thin the glass is

I actually like your project better than the " U " shape tube design,.. Thumbs up bud!!

I wondered how those worked. Thanks again How would you build a HOB diverter? Is there a way to have it end in a spray bar or something floating plant friendly?

Very Nice!

Sir can you make a tutorial a diy pokpo overflow aquarium..please

Unbelievable work Fishman, what are the chances I could contract you to build me one similar? Just watching you work I am more confident in your skills then I would ever be in buying something manufactured in bulk.

I'm thinking of crossing this with your matten filter with a slim sump same height as the tank to stop Guppiy fry passing through with a course sponge at the top of the matten for safety and possibly using float switches in the tank and sump for extra safety with a auto top up from container underneath 🤞

I run a couple of these overflows I like them

Neat build 👍

Very nice

Hey look who we have here... My self laughing friend :-) I didnt know you build tanks too... Good job i have a question. I saw some internal back sumps where there are some hole or lines in the bottom rather than the top like overflow. Can you please tell me what that is?

When will this glue fail? May I use Glass glue?

Wow that it so cool!!!!

Oh nice. I knew you’d make look awesome.. thanks for sharing Eric. It looks great 😁👍🏼. I didn’t get around to emailing you yet. Really sorry..hopefully I’ll msg you soon. Really sorry.

I always wanted to make the u tube out of acrylic. But I have no space where I live for a workshop setup.

Awesome Video Thanks for sharing FishFam NJAE19

title says "no drill"?

Looks amazing! Can that handle 300gal? Can you make for 600gallons? 😊

My viewer request video would be , Adopt me ! ✌💕🙆👪 Added to my playlist titled - DIY's for fish keepers 🙏

Most freakin complicated over flow lol

Why do you keep giggling sir

That's not complicated ... let me find a 10 year old to explain it to me. :))
