Looking for Pics of Closed Loop Systems

I'm planning an upgrade and I'm thinking of using a closed loop system and would like to see some pics to get a better understanding and some ideas. Also, my new tank will have dual overflows, would it be possible to use one overflow for the closed loop and the other for the sump/skimmer/fuge???
 
Heres mine with all the other pipes out of the way. Just finished it up yesterday. Pulls from the bottom and has 2 returns that will have LineLock on em for directing flow.

Here are some CAD pics of the closed loops in my system. It is build around two Oceans Motions (highly recommended, btw) closed loops:

This shows the flow plan. Note the color coding of the pumps

You can read more about the setup in my tank thread linked below.

If you need advice on flow - and now is the time to get it before holes are drilled - I highly recommend calling Paul at Oceans Motions. He is a great guy and he'll end up ensuring your system is designed right. He was a huge help with my system.

Good luck,

Nice specs everyone!!!!!

What pump would be reccommended for a 180g 72*24*24 mixed reef?

Also could I utilize the second overflow for the closed loop system?
 
OM does not have a pump. Heres mine from the back.

I dont have any fancy CAD pics. Just the real thing.
 
I run a Dart on a 120 and it works okay. I have 3 holes drilled for the return w/ T's inside the tank. If I had a barebottom, I would probably upgrade to a bigger pump. With a 180 I definitely upgrade to something bigger than a Dart. My pump requires 2" intake so I drilled two 1.5' holes and have them T to a 2" into the pump. I drilled two just in case one clogs up a little bit, it shouldnt cavitate the pump.

As far as using the second overflow for a CL, I dont think you will be able to get enough water though it to run a big pump like hammerhead. I would keep both overflows going down to the sump so you can get good surface skimming and in case one gets clogged, the other one will help out.

I would recommend to do a hang on the back overflow so you wont have to drill the tank and in case you dont like it, you can take it out. A oceans motions is the way to go if you want alternating current. It has a motor in it that changes which pipes you want water to come out.

As for the German thing, I dont care how good of flow it makes, it would look hideous in tank seeing that thing take up both sides.
 
Thanks, Patmack!

I researched pumps like crazy. In my opinion (and Paul at OM will tell you the same thing), the best value and most efficient are the Sequence Reeflo series. They are VERY popular on this board and a lot of tanks of the month use them. Here's the conclusions I came to:

Reeflo Dart - this is the "gold standard". It was the quietest and it is very reasonably priced. It is also way more efficient than the competition. That juice adds up over time and efficiency is key.

Reeflo Dart Gold - this is brand new and you have to ask for it. It is even more energy efficient than the Dart and it puts out more flow for less juice - all with the same head. It is also quieter and cooler. The problem is it is way more expensive. For me it was worth it.

If you want even more flow you could go to a Hammerhead, but that's overkill in my book and the added cost of electricity will hurt. They are also a bit noisier. On the plus side, it has more head, but that's not a problem in a closed loop.

Here are some specs and prices I collected:

d. Snapper $209 2400 gph 11’ head 2” in and 1.5” out free shipping at reefexotics
e. Dart $229 from Reefspecialty 3600 gph 145 or 160 watts 12’ max head 2” in and 1.5” out / $229 free shipping at reefexotics ($230 from TPP)
f. Dart Gold 3800 gph 13’ head 132 watts and quieter $370 from Reefspecialty.com ($389 TPP)
g. Super Dart Gold 4300 x 13’ x 165 watts $431
h. Barracuda 4300 gph 20’ 1.5” in and 1.5” out 225watts $299 free shipping
i. Barracuda Gold 4580 x 21’x237 watts $494
j. Hammerhead 5,800 gph 335watts 23’ head 1.5”x1.5” $329 shipped
k. Hammerhead Gold 5555gph x 23’ 272 watts $629

Please note that Paul at Oceans Motions offers one stop shopping and can get you a package deal at least as good as the above prices.

I would recommend a Dart - unless you really need it to be incredibly quiet (i.e. quieter than the quietest comparable pump (the Dart), in which case I'd go with a Dart Gold.

I hope that helps.

Klaus :

It's Excellent Idea , I always thought to do the same on skimmer double wall , the one with the holes shorter.....

did you ever test it ?

New Ideas ? Look here.... German development..... laminar Movment...

@Mavgi... (Michael)

thanks... yes, i building a 1000 Liter Testtank at the moment. I want make the first Reeftank, with laminar movment... The closed Loop Pumps are 2 x 22.000 Liter RD2 with Ocean-Simulator.
When the Tank is running, i make a Posting in Proline-board...

best regars...
 
Klaus,
Nice rendering:) You would need a LOT of flow to prevent dispersion through that many holes.

Paul (OM) and I have talked about building a tank like that too. His new device recreates that same flow pattern though with nozzles.
Here the effect is shown:

@H20ENG

tx. for the Link... very impressive..... so i now the flow with Pipes via Closed Loop Systems.. the problem of all Pipes, he don´t make laminar movment. I building many tanks with 10-15 pipeoutlets and you have a turbulent movment. So i want testing with a special-tank, only for laminar movment. I using very powerfull Pumps where have speedadjustable Rpm ( DC-Pumps ) so i hope, i can revolution the movment for Reeftanks. I am longer as 25 years, never happy with Flowmanagement in my tanks.....

regards... Klaus
