    Hi There, with the price of electricity going up all the time im look at saving power.Im looking for ideas for an up pump @ +-5000L with the least power use. Ive seen a Reef Octopus Water blaster that uses 60W @ 5000L 3.5 Head. Is there any other pumps out there?

    Hi RedHawk - why would you want a return pump that does 5000 liters per hour? That is HUGE mate! What size tank do you have? And what is your sump size?

    How far (in meters) does the pump have to pump the water to the tank?

    Whoa, huge you say jacques? i have a a 200L tank with a 6500L return, is that too much? i am paranoid now as i have had algae problems, could it be that the water is not being properly 'processed' in my sump :( ahhhh, im not home for another week or so!

    Yes Deadmeat - and you DikDaan. I am not 100% sure who would have advised you to use such huge return pumps.

    You must remember what you are trying to achieve here, with your sump. IF your water flows to fast through your sump, then the sump will NOT get a change to "clean the water" properly.

    You should use in-tank power-heads for water flow. A return pump is purely there only for returning the water to your DT.....

    And Deadmeat - no need to be paranoid mate ;)

    BTW: MY DT volume is +-700 liters, and my sump volume +-800 liters. I have a 3500 liters per hour return pump, which pumps the water +-4 meters back to my DT.

    I also have to detune (throttle) the return pump quite a bit, because my water overflow downpipe is directly connected to my skimmer, which then dumps the water into my sump system. My skimmer also throttles the water flow to my sump......

    Dikdaan - I would rather suggest one of +-1500 liters per hour, maximum. You can actually go for a 1000 liters per hour one, if the head length is not too much.

    So in theory you return is less than 2 X total volume Jacques? What would your nett flow rate be after head and pipe length?

    The nett water flow from my tank's return pump, is +-800/900 liters per hour.

    And yes - my total water volume, is +-1500 liters. My return pump is rated at 2500 liters per hour.

    My whole sump system cycles all the water within itself (my "sump" consists of 6 x 90cm tanks) about 3 to 4 times, before the water volume is returned to my DT...

    The whole cycle from the time that water leaves my Display Tank, till the time it returns, takes about 1.5 hours.

    No - definitely NOT 10x the volume of the display tank. Regis - where would you have read this? I would like to correct the people who wrote that.

    Remember - you are trying to achieve one thing with a sump: FILTRATION OF YOUR DT's WATER.....

    That can only happen, IF you give your filtration media/methods a change to do it's thing.....A skimmer can only skim water that stays in it's body, for a certain period of time.

    A DSB can only work - IF the water flows slowly over it..... As can live rock only be a filtration method, IF the water runs slowly enough over it/through it - to reach the rock's centre....

    And - macro algae can only do it's magic, if the water is around it for a long enough period of time..... ;)

    Cool Deadmeat! It's not a train-smash to have changed urgently. BUT, I would advise to change the return pump at SOME stage in any case. Just take into account that the chances are highly likely, that your filtration system is not working the way that it SHOULD be, due to too fast water flow through your sump system.
