Max or min flowrate for Sps

[andysho]

i wonder wat is the average turnover flowrate for sps keepers

here?

The average of a sps tank at least have to be 20 or 30 times

the water volume of the tank~ correct me if i am wrong

mine is 200 litres tank ... turnover rate is around

10000 litres

I dunno min or max but it's 110x in my tank.

sump turn over + tank turn over.

180L Display 200L Sump

12,000L TS12 and Return HF20 5,000L ( may be 2,500 after head loss ), so technically I am running over 100x.

Feel like need more cause TS12 pulse ....

It not always the turnover rate is important. It's important yes for filtration purpose so that sufficient flowrate goes thru your skimmer, etc.... but it's the amount of random flow within your tank that plays a great deal more to your SPS.

IM-Exp.......Strong current doesnt mean healthy sps.....the current got to reach them...

My acros in the old tank still exp stn prob when the current dun reach the base of the acros....(partially blocked off by acros/corals infront)

I have more than once created mini dead spots with closely packed acros with insufficient provision of current to reach them.

(I was using 2 6060 tunze pumps + 3 other power heads)

38X in my case. With the vast majority from the 3 x 6100s pulsing from 50% to 100%. Turnover rate to my sump is purely meant for the chiller loop and skimmer to constantly process dirty incoming tank water.

Waiting for the 6200 to arrive!

1000 litre tank, running two Oceans Motions 4 ways each splitting to 8 outlets. 1 has 6 outlets on at any given time, the other 4.

The closed loop return to 4 outlets at once, 6 mounted in the bottom pane of glass, 2 in the rear panel

The return pumps run to a manifold across the top, into 8 outlets all with Oceans Motions revolutions fitted.

Sequence pumps driving both closed loop and return, totalling up to about 40000 litres per hour after headlosses etc... so 40x tank turnover, with not a powerhead or pump in sight in the tank

I agree with deeblue too~~ sometimes we cant just by looking

at the wave and determine whether is it sufficient for the sps a not

Most impt is that the current have to reach those sps corals,

esp those very packed branches~~ where reaching them become

a problem~~ so the way how we place our wavemaker also determine

the amount of flowrate that reach sps

bascially i have place my tunze and seio wavemaker in different location

to see how it affects my sps~~ i have observe that my lower base of my

sps seems to be spreading however the upperpart not much growth

so if i am not wrong it might be lack of flow among them~~ so going

to position my my tunze pointed more upwards and see how it goes
