What a difference it makes when you have this reef studio. So many projects keep them coming. Looking for more as always.

I know it's really off topic but i love that Pokemon shirt xD

Plumbing tip. Always use primer. I used to not think primer was necessary but after taking a plumbing class I learned you can actually bond two pipes using just the primer. The pipe should be cut as straight as possible. I prefer a miter saw and only use the ratchet or mechanical pipe cutters when I can't use a saw. Then chamfer the edge of the pipe to deburr the edge and cut off any lip created in the cutting process. Then prime the fitting aggressively, then the pipe, then back to the fitting quickly to ensure the primer is WET when the solvent cement is applied. Apply cement to the pipe, then the fitting and a quick layer back on the pipe. Push them together, if you can give a little twist as you push in. If plumbing larger pipe you may need more help. When done this way many people will be surprised as the pipe will actually try and push out of the fitting more, so you usually need to hold it a little longer to get it to bond properly.

So excited to see this series! This aquarium is going to be epic!

Closed loops can be a very affective type of filtration. When we set up a system we always try to go over the worse case possibilities, the thing to consider is leaks. If a fitting fails, an o-ring failure (8 O-rings in this set up & 4 gaskets in addition to the glued joints) what is the worse case? In this set up worse case if not noticed total tank drained (to lip of bulkhead) and pumps run dry. If it would work for the look of the aquarium having a short riser (maybe 6") would at least save the fish in the short run in a complete failure. A lot of things would need to go wrong but failures always seem to happen when you are not there to catch them.

Can’t wait to watch how this tank evolves. I just setup my first closed loop system and love the clean look of no pumps or wires in the tank.

Really diggin this build!! Have been very interested in the bottom.of the tank since you unveiled it. The fact you could flush mount the gasket which would pretty much garuntee you'll never have squeeze out is a killer idea. Also going old school with the closed loop is bringing it back man, well done

Jake - love the direction this build is taking and the closed loop design. I think this would be a great opportunity for a few Random Flow Generator Nozzles. Lets pop a few on the ends of those closed loops. :-)

WAHOU, que du beau matériel !!! Merci Jake ... 💪💪💪

I love that setup. Man, that looks so nice and clean. Wish I would have used a closed loop on my tank when I plumbed it. A+

Closed loops are an intriguing aspect of establishing tank flows while also maintaining a discreet appearance. However, when compared to the convenience offered by many advanced power heads available in today’s reefing hobby, what are the primary benefits of closed loops? I recall experimenting with closed loop designs in the past, but the availability of reliable power heads was limited. Nevertheless, the constant concern about potential leaks and floor damage due to plumbing insecurities can be overwhelming. It's reassuring to see that you've positioned it in an area where flooding isn't a major concern. Nonetheless, the maintenance demands of closed loops are substantial, involving regular pump cleaning and dealing with issues like intake clogs and seal leaks. Despite these challenges, your design and craftsmanship are truly impressive.

Fantabulous work!🤗👍🏼

Awesome work Jake!!!😎

Oh, and make sure your sump is under those pumps, because even when you close off the valves you're going to spill a good amount of water when you disconnect them.

Its very nice work and beautiful piping.

I think drilling some holes in shelf rock pieces around that 1.5" pvc outlet protruding from the bottom would look cool. Stack them up using a piece of straight pvc rising up about 2/3" - 1/2" the height of the tank, with the 90 on the top end, perhaps even a T fitting . This would effectively almost hide the pvc within the rocks, and that vertical pvc would be the spine of sorts for the rock structure. I think that would be slick to do, and you could even arch between the left and right side with some Mortar and regular reef saver rock... Thats my eye deer. Looks awesome so far!

I also made a spray bar a few weeks ago adding on UV sterilizer made it closed loop(dino-snot prevention), battle was "successful" for my level I think. But the 1/2 spray nozzle was a big help pointed at the Monti cap and eliminated turkey baster maintenance with no pissed softies/lps, one less big chore lol

Verry smart plumbing!!

That setup looks awesome and the symmetry makes my OCD calm down lol thanks bro.

My ideal is similar but I would put two can filter pumps on each side of the tank. It would not only create a nice flow like power heads but it would also filter the tank at the same time. so no pipes or wires would be visible. especially if you use low profile bulkheads with strainers for the out puts. I even use external heaters that are attached to the can filters, so it keeps the water warm for my tropical fish.

I like the closed loop can't wait to see the sump and the plumbing that goes with it. 🐡

Big floating shelf aquascape

Awesome job there Jake, looks clean AF ! I'm a fan of the branch type rock which might look dope ?

Killer setup, great video as always. I never thought or seen a floating motor, but I Like it. Presently doing a build-out of a 1000 gallon saltwater. Part 16 just released, going FOWLR. Kicking around a closed loop, but with the acrylic being 2 inches thick, makes for an issue with the bulkheads. Be sure to check out the channel.

Great job. I agree with this philosophy. It gives you great water of flow from bottom up. Now that you had this for a while, do you think this is the way to go? and can you live with out water pumps on the tank walls like ecotech MPs?with this closed loop I wanted to know since this is such a clean look and moving water in places that other pumps can

Wow that’s awesome 😎

Thanks Jake. Hope heaven is amazing for ya.

I've been waiting for this since you setup the tank

Beautiful job.i love u videos addan I wish I work with you love work with tanks thanks for the videos keep up for are community

Whenever you glue a ball valve, always make sure that gravity pulls the glue away from the internals!

floating islands!

Floating scape for sure!

three or four bomies with the closed loops hidden inside them would be cool I reckon 😂😎 could do some nice 360 degree sps bomies

You won't need to put any supports in for the pumps, the pipework is strong at that diameter and the lengths are extremely short so they will be fine. Looks awesome!

Totally awesome sir ❤️❤️❤️ lots of love from India ❤️😌

Question. so your pulling from one hole and pushing it from another. one, i assume this is going to be bare bottom or otherwise everything will be sucked in or two. how do you keep things from getting into the intake? i dont get it.

Hello Jake I’ve just watched the video and when you said aquascape I think your should use the ( two little fishies Stax rock) I’ve just got two boxes and a mate of mine has used it as well he has three closed loops and was able to build a structure around the outlets

I would put supports under pumps to the wall. Very cool tank!

Looks super clean, and it was great to see you do the actual plumbing, so we have an idea of how they should be done properly 😅 btw, nice IO shirt!

I'm in the planning stages for...a few aquariums actually. I'm trying to figure a smaller scale prototype first for what I'm thinking of. Ive thought about a closed loop-especially with those vectras. Flow? That configuration? Open drain valve on wallet-voila! 😜 Short runs. Few elbows so you don't loose as much head. The valves you've got there? Maintenance? Perfect! 👍 So for all the other stuff like skimmers, kalk reactor's, UV sterilizers, would you prefer another line with a sump of some sort or...another separate branch from a manifold to extend that loop? I'm curious as if I could work that out without a sump...😁 thats food for thought and way less complicated than what ive got in mind. Secondly, uhm...metal junction box? 😕 I made some mistakes early on and I had some serious salt creep. One day, I noticed my strip socket was charred. For a closed loop? If there's virtually no way you're going to have a leak, maybe. Personally? I'd prefer to resplice all the power cords to somewhere away from the water just for that reason-if I had a sump. Salt creep? Moisture? Electricity? 😕 I had to call OFD once for something and do not want it to be for something like that. 😕 Other than that, this has me thinking redundant closed loops in tandem. Sump container then becomes drip pan or splash shield. (Shrugs) That way if something major happened, there would be enough volume to collect whatever comes from the overflow configuration you've got whatever that is or its equivalent. (Shrugs)

Super clean work Jake! Would love to see this jumbo pool filled with "high grade" acros, not fancy name high grade, i mean the real deal. ✌💪😎

Its gonna be very useful

Nice work! Curious why no unions connected between the buildhead and first 90 elbow. Or true union ball valves... If you ever have to disassemble this your gonna have to cut everything and start over

Would love to see a floating tonga rock aquascape with easy ways of putting it together.

Your hair looks really nice. Don't know what you did differently but keep this way.

Hey Jake, how is this closed loop system holding up? Did you ever support the pumps? Any constant noise or vibrations the way it was setup in the long run? Now it has been over a couple of years since this install.

Only pvc glue no primer?

Merci super Closed Loop j’aimerais comprendre SVP on ne Voie pas le présage pour la descendre dans la partie technique (le sump ) ??

Is there a video showing the filtration system set up?

Hard to explain but when you dry fit your pipes & fittings before gluing you can use a marker pen to draw a line across where the pipe & fittings join. That way after you disassemble them to apply the solvent weld you can see by the marker pen lines exactly how to reassemble them with no need to move or rotate fittings to find their correct positions while they are in the process of bonding.

Jake whats the stand made out of? I'm building a custom 390 gal. tank 32tx36w84long and not sure if i want to use wood for this build. thanks

Have you thought of a way to screen the inlet bulkheads? would hate to see it suck in some coraline or a small dislodged frag/piece of coral... or a fish even, that things moving some water!!

Aaa amazing

Jake, love it! One question, how will you keep stuff out of the intakes?

Jake Adams-the Nigella Lawson of reefing👍😋

I would suggest the ingress and egress be as far apart as possible so that water would travel further. Maybe just one pump from hole 1 to 4 would be about the same result as 2 pumps from 1 to 2 and 3 to 4. Less electricity, fewer points of failure. Would suggest schedule 80 for the bulkheads because if it leaks, it rains all 400 gallon out. Also it would be nice to install an apex flow sensor to see how much the flow is. I would be surprised if u get 70% of what the pump is rated for.

Hey Jake great video as always! I just have a question, don't you think that installing the pumps upside down is going to have a negative effects on the hard plumbing? How do you plan to reduce vibrations?

Hello! This system is amazing! In Brazil has a excelent aquatist “Joao Carlos Basso”, he improve this system, creating a closed loop with only one hole on display. With only 1 pipe, he makes up and down water. In hes KZfaq channel can you see that. Congrats for your project

The washing machine is running 👍🏻

This may be a dumb question but if the pvc is only on the bottom isn’t it going to kick up the sand?

Did Indonesia’s release the ban yet.

I think this tank is perfect for mud substrate😆

hi Jake love you studio and videos, about 6-7 months ago I added a rainbow monti, I trusted the source however the one time I dont qt I ended up with Monty eating nudibranch, anyway all my monties died off about 5 months. question is how long should I wait before adding montipora back in my tank?

Arches!

Why not use the curved elbows (just a little taller) on the outlets in the tank so you don’t stifle the flow w a sharp 90° turn?

I'm currently building a 220 system, And consider doing a closed loop the problem is with new tanks you never really know which panels are tempered and which are not So for fear of shattering my brand new tank I'm going to skip the close loop

Use a clear fitting inside the tank to elevate a rock structure so it looks like it's floating

Say don't mean to bother you but I was sent to you for some advice I'm getting ready to setup a new reef tank and my question to you is my overflow holes are 1" and my return holes are 3/4" I plan on running 1" all the way to the sump with my overflow drains. Now the real question is on the returns from the return pump how would you plumb it my Outlet is 1 1/4" what would size plumbing would you run to the 3/4" return hole 👍👍looking forward to your response

Damn I wish I could Afford a 400 gallon tank!!

I wonder if you would benefit in adding a spray tube along the bottom just like the 20 gal jbj frag tank has, just to keep organic suspended? Hmmmm

Здравствуйте, и это рентабельно по сравнению с помпами течения?

Awesome build brother; what is going into it?

Tube bending, heat and flex to the angle you want. I think Than did that.

I'm wondering how you're going to screen our keep dirt and junk from falling down into the inlets

How do you keep debris from the intakes and what does maintenance look like?

try a pvc aquascape, pvc takes the place of tonga branch

Please do a aquascape like Rico's aqueriums 500g or Wayne dislets 205g

Are you using primer with the PVC cement?

What’s the use of close loop without a sump ?

Why Closed Loop? Is there an advantage? And how will you filter the water?

Was that a Coors I seen in the video Jake?! I would love to see a bare bottom with multiple pillars of different heights!! Paul H

Question about closed loop systems. They look really clean, but am I just being stupid and not figuring out filtration such as a sump and such.

Looks great. If it were me I’d wrap that black wire with some white tape :)

Vibrations may cause issues. Better use something to support the pump.

You have to do something with random flow generators. Idk what but something.

Update on this please?

I say do 3 bomis with rainbows connecting them together..

Wont sand and rocks get into the pumps?

How do you prevent livestock from entering the suction?

What are the dimensions on it 8foot buy what buy what

15:18 (Oh Yeah) 😜☝🏻

Primer ?

It have not to be screwed whilst putting it together

consider the risk of the Loop sucked by the fish or other things?

fish or any other things will not be sucked to other hole ? Where the water goes in ? Or you will cover that water entrance hole with something? can you please advise as i want to make same system.

Dude are you also an actor? You were in the Netflix movie ”6 underground”

Get a company to build it, there's company's who let you design it with a 3d model, like Aaron's aquarium. Check his out, it's amazing so open lots of room for flow

Ok, I know this question has been asked several times and your response is the same "several layers of pre-filtration. I'm still relatively new to the hobby so I also do not understand. Can you please outline the benefits of this setup, and a little more detail on how it works. I mean, are you going to extend the inlet? With that much flow you're going to be making fish smoothies.

Are you still playing Pokemon Go?

Don’t you lose flow velocity by going to bigger bulk heads and returns. Won’t your flow volume be regulated more by the pump, with velocity a function of the diameter of the tube. Narrower, higher velocity.
