I have 2500 gph in my 30 cube- little over 70x
What's your turnover rate in your sps tank?

49.31x in my 36g. 2x koralia 1050's, one timed to run for 5 mins, off for 5 mins, plus an mj1200 behind the rockwork.

I don't know how you guys can get away with so much flow.. I have a mixed reef with two mp10s, and around 500gph return. This is for my 92g corner tank. With this flow it's hard not to deflate my Lps corals, the flesh gets deflated down to the skeleton and I need to move them into a lower flow area. Then some SPS near the top of the tank get blasted so hard that they pull in their polyps.. I would like to add more flow to the rear of my tank but it's already like a hurricane in my tank
My 150 has an MP40 on reef crest at about 80 % two Koralia 8s, one Koralia 7 and the return is a throttled back T4.
My general rule is I need the following:
(Note: I said "I need" becuase if I said you need that would open the door for rebuttals, I'm not intersted in what you think I need. I am interested in what you do and think you need. I like reasons why.)
- at least two at right angles for mid height flow,
- one low for low circualting flow (optional with a vortech, maybe), and
- one high and angled slightly upward to make a rolling action out of the surface of the water all across the surface of tank water.
IMO there is no point in calcualting xx.y turnover numbers becuase the rated flows from MFRs are for single brand new pumps alone in a test chamber with some liberal math & liberal assumptions.
In a real tank many factors affect flow, such as algae on the powerhead or pump screen, two PHs pointed at one another, water hitting rocks etc.
I also think its best to ignore the return flow, it has a purpose other than tank water movement, just let that be its purpose.

I have a 55 gallon tank. If i put to k4 on each end and point them to the center facing down will that be enough flow for my tank to keep my sps?

around 100x right now
How do you guys get these high flow rates without causing a sandstorm. I have a mixed reef with some SPS and if had turned up the flow like that in my 37 cube my poor hammer and duncan would be torn to bits.
90X?
In my little tank only 24 inches wide mind you, that would be 3367 gph! I'm worried it already too strong and I have only 1440gph which is 38x.

as the tanks get bigger the flow rates needed exponentially grow. Tons of factors to consider aswell like shape of tank and rock scape. Think of the flow as if it were sound waves traveling through the air in an empty room versus a cluttered room. The empty room echos and roars while the cluttered room is absorbing the sound waves.
At least the general numbers seem to be 60 to 100x. Somewhere in there would be a good starting point.

I think another consideration in tank size is distance to livestock from the pump outlet. The pump outlet flow speed doesn't change depending on which tank it's in( assuming the same setting at controller) but in a ten it might be 2 inches from livestock whereas in a 250 it could be 10 inches away. One would rip flesh and one would not. So point being we have to scape and stock a little differently depending on tank size and adjust flow accordingly if we cannot gain distance from pump outlet.One might be recieving max velocity off the pump at 2 inches and at 10 inches away in a heavily confused flow tank the other might see 30 percent of max velocity after being hit by counter flow,corals,etc. So don't get hung up on flow numbers. Is the rock work staying clean and are the corals responding well. JMO

sorry for the stupid question but way do you need high turn off rate?

Thank you Allmost that is good information. One of the biggest things I've worried about it to much follow hitting some of my sps corals, this has always had me wonder what the sweet spot would be.

300 SPS dominated
return - Reefflo Hammerhead
2 - tunze 6305
4- tunze 6205 for a total of 44,594 GPH
BUT the Tunze's are on wave mode so a little less.:beer:

Do you keep any low flow corals like bubbles , hammers etc or strictly SPS? How do you keep the LPS from being shredded.
