Flow in a 2000 gallon Deltec tank

Arnar, I would seriously consider looking into penductors

http://www.aquariumspecialty.com/catalog/product_info.php?products_id=796

These will use whatever pump you have to draw water in from the tank and increase the flow from every outlet. Using a high pressure pumps, you could conceivably increase the flow from those pump outlets by 3X-5X. So for a pump that moves 5,000 gph, you get 15,000 to 25,000 gph of total flow from those jets.

Hope that helps at least a little for such a big project.

Overall, it sounds like on hell of a project.

what about multiple vortecs on the back wall this way you have less electric and items in the tank. I have a 560 with tunze's and a seq on a cl. CL are very bad on efficiency. If my tank wasn't a peninsula I wouldn't have a close loop at all. Look at what a hammer head draws vs a tunze or vortec . as of cost factor its about even when you think a hammer is 300+ plus plumbing ,penductors,valves,om4 or 8 ways ect. Also the point that as your tank changes you can move the tunzes and vortecs where you need them.

Thanks for the tips. I think I'll order a few penductors and try them.

nyvp: I thought about that but I like that I can hide a lot of the plumbing for the closed loop in the rockwork. I already have 4 tunzes which I will use as well but I want to keep the tank as clean looking as I possibly can. The tank is also so long and wide that I would need a lot of tunzes to cover it all and they are not cheap.

6 waveboxes across one side should do the trick for surge! This really is going to be awesome.

I fully agree with the suggestion earlier of a couple big 1HP commercial pump for the closed loop.

this is going to be a beautiful tank. but before the water flow system can be truly designed properly you need to describe the inhabitants that will be housed in this tank first. is this a full reef with all sps corals or will this be a mixed reef with softies and lps with some sps here and there? there is alot to consider with a tank this size. you could put in a closed loop and have nothing but problems. then there is the rock work. how will that be set up inside the tank? will there be open areas for fish to swim and caves for rest from the flow of the closed loop system? what kind of fish are planed for this tank? big of small? the tank that is the closest in size to this one is energys 1700 g reef. its 15 ft long 5 ft wide and 33 " tall. its almost identical sized. he uses multipial ways to circulate water through his system. there is other alternative ways that are not mentioned here tha may be good ways also. say for instance use 2 or 3 surge tanks and some 6300 tunze streams. set up a tide pattern of sorts to mimic the ocean more. mabe some wave boxes hidden in the rock work to break up the flow of the closed loop system and make more random flow through the rock work. there is many ways to create the right flow pattern inside a large tank like this. its all a matter of what you have the room for and how you see this tank going together and what system best fits the needs of the inhabitants.

just my 2 cents worth.

any updates???

I wonder if Arnar did order another set of 4 x 6200

 

[stdreb27]

sounds like fun to me.

in a tank that size i think 2 tunze 6200 on each side will be fine on a wave cycle.

Anxious to see some pictures!!! looks like it will be a crazy project!!!

-Good Luck!

I think I got the flow mostly nailed down to start with when the tank arrives and then I'll add as needed

There are now two threads on this aquarium, so I guess it's best to keep it simple and use the one in the link http://reefcentral.com/forums/showthread.php?s=&threadid=1075675
