    I have the dc5500 on my reef octo skimmer and could not be happier with it. Also have a dc5000 as my return pump.
    Both are very quiet and perform extremely well. I had heard about issues with head height but haven't seen this on mine.

    can someone clarify for me? surely mixing a DC pump and water is a really bad idea? what are the pro's of a DC pump over an AC pump?

    Thanks

    Why do you say its a bad idea?

    The major benefit of a DC pump is that it can be controlled. And so far they seem more energy efficient than the AC equivalents.

    DC vs AC

    AC 220 volts will kill you. DC will not, 12 or 24 volts. This is the biggest reason to buy these pumps, IMO.

    Just a thought a return pump @ 10500 l/h flow thru the sump with deep sand bed. Doesn't a deep sand bed require a slow flow over the sand.

    not too slow either.
    The water head should be between 6 to 10mm
    That is the height of the water as measured between the top of the last divider and the actual water level

    Thanks for clarifying!
    I have 2x dc pumps, one in the skimmer and my return. They are brilliant!

    A other option that is available to me is to set up a cube 650x 650 x 350 as a deep sand bed. I am still worried that the flow is going to be too much with the dc pump in a normal sump setup. @ RiaanP Thanks for all your replies. The 6cm to 10 cm head that you are talking about is that a crucial element or factor for a deep sand bed. What do you guys think of a remote tank (650x650x350) as a dsb

    6 to 10 MILLIMETER
    that is the thickness of the flow as it goes over the divider.
    Less than 5, and you end up with settlement.
    Above 10 and you can end up with sand storms.

    I got a DSB under the display, in the "normal" sump, plus another DSB in a remote tank. Tank is a 750L, 1.5 by 750 by 750mm Main DSB is 800mm by 600mm. Remote DSB is a standard Daro 1.2 tank, so, 1200mm by 450mm

    Remote DSB also doubles up as a refugium
