pipe to scwd

[reefer guy]

1262... err... what's the flowrate? problem with scwd is if flowrate is weak, it tends to just 'flow out' and the switching is slow.... if flowrate is strong it bursts out really good but the switching is fast thus making the currents made shorter... it would be great if u could adjust it perfectly considering the pump flowrate, ur head loss, and pipe turns and lengths....

can someone advise on how scwd function...

1262 flow rate at 3500l/hr...but after pushing water from the sump to the scwd in the main tank..surely drop by quite alot..but i suspect the CR you use will drop even more ..not sure..but highly likely...

the 1262 pushes water out quite fast..the switching from one direction to another is about 7 to 8 seconds...the water came out quite fast and forceful to me...still create big turbulence on the water surface...

its just a simple device wherein ur powerhead/pump is connected to a 'y' or 't' outlet and it will simultaneously flow from one end to the other thus making a it a double headed snake.. heheheh.....

all most of us know is that the water entering turns some gears such that water outlet alternates between left and right outlet arms......someone posted the scwd internal mechanism before....i see if i can find it...

yeah...true... i put the cr pump in the sump n its too weak a current, considering i have 2 90deg turns from pump to scwd and another 2 90deg turn for each outlets, PLUS my head loss, tank is standing 5ft high

but then again, stucked my cr in my main tank and walah!!! there goes my strong current...

never asked reeferman from reefcentral before using his pics..but at least i give reference to him

here are the pics of what is inside a scwd..

i noe how it function liao... thkz...
