to much flow??????UPDATE

[carlinsa]

ok right now the way it stands i have one tunze 6060 in my tank for a little extra circulation. but i will be running a oceansmotions fed by a dart pump. at the end of the lines will be eductors. my return pump on the tank is a mag 18. both the dart and the mag have about 3ft of head.

6060-----1600gph extra flow
dart------3600gph hooked to oceansmotions minus eductors
mag18---1800gph return pump

total------7000gph

my question is to be as follows........ does this sound like to much flow??????? the tank is a 125 :D . should i take the tunze out or let it just help provide more circulation to an already SWIFTLY moving tank. i am also thinking about UPGRADEING the return pump to a mag 24 or some other type of high flow SUBmersible pump


ANY THOUGHTS????????????????????

hope its bare bottom...

Well you asked for it!
Take out the Tunze, downgrade the return pump, and be ready to throttle back the Dart!

Ok ... here is my reasoning:
Return Pump: I like to run about 5x through my sump, this provides a gentle non-turbulent flow through the sump for bubbles to escape and for settling/filtering to take place. 5x through the sump for a 125g is about 625gph. Actually less because you don't have 125g of water after you subtract out glass thickness, substrate, and rock. The MAG18 @ 3' of head is about 1500gph (12x!!). My favorite submersible pump is an Eheim, although it has metric hose barbs and a bit of a pain to connect a hose to. An Eheim 1262 is 900gph @ 0' head, couldn't find a chart on it, but probably around 700gph at 3' of head. So it's probably about right for this size tank. If you like MAGs, maybe a MAG12?

Circulation: I am assuming you want to grow SPS, so 20-30x total water movement is your target (2500 - 3750gph) - 30x is better. Subtracting out the return flow (call it 700gph), that leaves 1800 - 3050. With head pressure and pipe bends for the OM, the dart may be about right for this, but maybe a bit strong, so install a ball valve on the outlet side so you can cut it back a bit if needed. You don't need the Tunze!

You didn't mention a skimmer or pump for the skimmer - it that all seperate?

Let the flames begin :P

[carlinsa]

yeah the skimmer is seperate and has its own pump. no it isnt running bare bottom i an running a return and wave system much like our prez does. except he has 2 darts. one to feed the return and the skimmer and one for just the oceansmotions. so that is why i am asking i want the growth and the turnover to make things grow and live

[gjuarez]

The Prez doesnt have a tunze in the tank though and his tank is a bit bigger. I would worry about having sand storms. I agree with Steve with less flow through the sump. It allows for unwanted stuff and particles to settle in the sump instead of it going back into the main display. I learned that its better (IMO) if a return pump isn't used for flow, just as a return and look for other ways to provide the flow. I think I would ditch the tunze, the eductors on the dart will probably be enough. BTW, if the sand allows you to, I would keep all the flow. Just maybe reduce or downgrade the return pump.

[akm]

How much rock are you planning on putting in? I have a 90 with about 4000gph of circulation and 1100 gph for the skimmer but have have about 150 pounds of rock cutting down some of the flow.

[gjuarez]

good point

[brewercm]

I agree with Steve.

That and you can give me the Tunze. ;)

[carlinsa]

going to have about 150 175 pounds of rock

[::pete::]

Toss the Tunze

[fishypets]

I thought the wave box in addition to a 6000 and 6100 stream would be too much. Boy I was wrong. My sps love all the flow. You should try it before you decide either way. And yes I have a sand bed.

[gjuarez]

Tunzes are awesome, I have a 6060 on my 29g.

[carlinsa]

Right now i just turned on the dart and oceansmotions. NO sand storm. does cause a nice little rocking motion in my tank as it switches. must say so far love the device and i have some serious flow in my 125. but as soon as i get some things in the tank other than sand an rock i will be looking at trying what steve said if things seem to blow all over the place

[::pete::]

I swear by them ... the OceansMotions units rock and beat a Tunze hands down !!!

[carlinsa]

true i spent 200 on the oceansmotions and 200 on the dart. 400$ total when A tunze is what 300$

[::pete::]

Yes but then you need all the extra componets ... and it is one direction from one location ... need I go on.

[carlinsa]

no waht i am saying is that for $400 you can cover all four corners of your tank and save a few hundred dollars. it was said to be a good thing

[fishypets]

Does the O.M. do the same thing as the wavebox? How hard is it to clean?

[::pete::]

Clean ... rarely depends on the detritus in the water column. It does better than a wave box. A wave box is back and forth the OM is random and from at least 4 different locations. Add an eductor or penductor and you have the gentle cone of the Tunze. ;)

[gjuarez]

Hey PEte, so with the OM unit its like having a tunze in each corner?

[fishypets]

I look at the heat build up from the pump and wattage. Tunze seems like it will be cheaper in the long run. Hard to beat the wave box IMO.

[::pete::]

With an added eductor or penductor ... yes.


I have 3 pumps on my system and it stays at 80 most of the time and the tank is in the garage.
Amp 3000 Return
Dart Closed Loop
Iwasaki 70 Skimmer

[gjuarez]

Wow, thats some serious flow.

[fishypets]

That's what I'm talking about

[gjuarez]

Mako, I have a maxijet 900 I am selling if you need more flow. : )

[carlinsa]

no the maxijet 9 would put him way over the top need to find a submersible hammerhead to turn into a powerhead or add a couple 6200 tunzes then i think he would be alright :D

[NaCl_H2O]

need to find a submersible hammerhead
LMAO :lol Don't tempt him!

[Ram_Puppy]

well I will have two darts running on a 115 shortly, lets see how that goes! (oceans motions 4 way)

[LoneStar]

Well I have a Tunze 6000 in a 55 gallon tank and a mag 7 for a return pump (with the head height it isn't much) but I want another 6000 for the other side!!! Depending on how you do your rock work Carl, the Tunze could work well shooting low behind the rocks to give flow back there and prevent detritus settling in rear....
