How Much does your tank turnover?

FiReBReTHa · Apr 22, 2009

JUST IN OVERFLOW

Not in powerheads, etc.

Example.

I have a 6g with a 106gph pump = 15x+
24g with a 210gph pump = 9x

Overflow should not be the main source of turnover. It should be in powerheads IMO

I messed up I have about 8 times or so on the return but I have about 3400gph in the 75. :)

so you dont have an overflow in your tank?
you lack the point of this thread!

I am merely measuring average overflow turnover. Nada else.

Fine I will play ;)

Overflow: 2 overflows with a single Mag 7 as a return on a 120g

After head loss with the mag 7 I am actually getting 431 gph so thats about 5x turnover from the overflow alone which is not much and I know.

BUT

With my 2 Vortech MP40s and my 2 Koralia #4s and 2 Koralia #3s in the tank I am right at 80x turnover rate

couldn't vote, i'm only 2-3 times per hour

7x via OF and 36x inc PH

120 gallon with a mag 12....
so would be around 10x and hour. but thats not factoring in the distance through the chiller and back into the tank. so would be less with head loss.
not including in it but i have 4 koralia 3's also in the tank....

I use a Mag 12 on a 65, in addition to a Koralia 4 and a modified MaxiJet 900, i.e., my water is always churning. I use a Mag 9.5 on my 40 breeder and a Vortec 40 running at about 25% capacity. Flow is king as far as I'm concerned.

i should mention that i depend on ph's for flow, and thus turnover is only to bring water to my skimmer and chaeto, in which case, i don't want it to fly through, i want it to slowly cruise through, dropping sediment as it goes

I have 6 with 600gph on a 100 gal total system volume.

Some are confusing flow with turnover, 2 different things, although like gparr said "flow is king"

gparr · Apr 22, 2009

Yes, there is a difference between flow and turnover and I confused the two. Salty's right, too. You don't want a raging river moving through your sump. Flow in my sump is rather slow, to the point that I've wondered about putting a Korallia 1 in the sump to move the water around a little. Not sure if it will make a difference.

I have two #3 Koralia's and a flow accelerator on my return for flow in the DT. I would put more, but I have lps and a dsb. I have no macro in my sump, just a filter sock and skimmer. I have a quietone pump with a manifold in my sump for my 2 reactors for carbon and gfo and 3rd output that shoots into the skimmer section and keeps debris suspended. My return section is calm so the debris settles and doesn't go back to the display.

cloakerpoked · Apr 22, 2009

I run a Little Giant 4-SCQX (or whatever the letters are) 1300 gph and a Mag 18 on my 120. They both run through a manifold, so of my 3100gph, probaby 500 is lost to head, 300 to the chiller loop, and 200 to the frag tank (a 29 gallon) so I'm guessing about 2100 or so makes it to the DT through 5 outlets and a spray bar. Also have 2 Koralia 3's in the tank for flow. My fuge/skimmer is a 20 gallon tank that gets half of the water coming from the frag tank. :)

oh whoops, i thought you meant total turnover
why would someone care about turnover from overflow though?

AZDesertRat · Apr 22, 2009

6 to 8x through the overflow/sump and another 35 to 40x with propeller/powerheads and a closed loop/Squirt. I try to keep the velocity down in the sump and refugium so the macroalgaes, skimmer and reactors do a good job.

Paul_N · Apr 22, 2009

what do you mean by total turnover?

FiReBReTHa · Apr 22, 2009

stay on topic peoples. this thread is the start of the next discussion thread. this is merely a poll and not a chit chat. next thread will discuss the numbers that we get from this thread.

mmmkay

Spiderwoman · Apr 22, 2009

Little Giant 4-MDQX-SC (1325gph) for return on a 150g tank. Chiller has it's own pump so no loss from that. Pumping distance about 3 feet, not sure how much loss would be there.

killingseed2000 · Apr 22, 2009

ya on my new setup, 125 long with a dart on the return, running around 1500 GPH which is around 12 , but the dart will feed other things aswell if anyone was wondering.
