How much circulation?

[wayne]

How much?
Does it look like much really?
How you doing it (powerheads, manifold, sump return?)

 

[wayne]

As a starter I have about 3000 litres perhour on a 250 litre tank, and I'd like more. Mostly powerheads + big internal filter, little bit refugium return,

My tanks range from 15-30 times and hour I love filtration.

30x an hour??...crimminy don't the guppys get blown around pretty bad?

i am at about 15x per hour on my 55 all coming from the sump. one pump (~360gph @ head) is through a single return. the other pump (~700gph @ head before SCWD) is running through the SCWD so that drops the gph down to around 500 or so I have been told

you can tell when the SCWD switches in my tank b/c anything long and tendraly starts swaying the other direction for a little while. neat effect. i wouldn't actually mind a little more flow but i am comfortable where I am and this is about all my overflow can handle

Have 2 x 401, 2 x 301, 1 x 201, ac500 for the current. I think now i have 2 much for my 55 g

The males are in the 10 gallon that has about 310 GPH and they love it

I angle the powerhead towards the corner that helps keep some of the trubulance down on the other side of the tank. the HOB filter is on the other side of the tank.

The swim all around and are having a blast no pun intended

the 29 gal has about 520 GPH

my forty gallon has aproximately 700-800 gallons per hour circulation, all except the protien skimmer are on timers, in a wave pulse pattern, my corals love it and grow very rapidly, my fish apreciate it as well

not enough--2x hagen pos 301 powerhead and a HOT Magnum return--definetly not enough

kahluazzz: have you considered running a closed loop with a badass pump and a SCWD instead of all the powerheads? like this: http://www.melevsreef.com/closedloop.html

dbacksrat: i think you are doing ok with the two hagens and the magnum return. the hagens are around 150gph each are they not? puts you areound 10x per hours

 

[KahluaZzZ]

yeah the guy who sold me the nova 2 had one. It looks better than 5 powerheads too

 

[1979camaro]

you bet it does...and it lets you alternate current which i really think is beneficial to some corals (i haven't done any research to back that up) plus it looks damn cool...not too hard to plumb either...just $$ (like everything)

umm
i feel like a moron but i have no clue how often my water is circulated

 

[1979camaro]

circulation is the ratio of tank size to how may gph total are your filters and powerheads...its mostly a saltwater thing we worry about

The more the better!
