    Hi all,
    I have just joined this forum,so I'm a newbie.
    I have a 50g custom made cube DT, plus a 10g sump, I had now for nearly 5yrs. Just recently I had to replace my old Jebao DC 6000 for the new DCP return pump, all is working well, I have just one question...that is ... I have set the feed on 60% with power outage reading 24 watts is this setting ok for the turnover or do I need to increase the flow? Or lower the setting for the flow? Any advice would be much appreciated if someone has the same return pump model.
    Many thanks

    personally i wouldnt slow the flow for feeding time
    i have a variety of fishes some much bigger than others
    i get a good distribution of the food and they all get some

    Thanks Jim for responding to my question, what I meant to ask was the feed setting of 60% for flow on the control panel, is this sufficient flow rate for my 60g reef cube? Or do I need to set it higher or lower ? Thanks.

    It’s a difficult one to answer because a lot depends on what filtration you have in the sump,
    I have miracle mud and it’s recommended that 10 times tank volume per hour goes through the sump.
    With Cheato it’s 5 times tank volume per hour.
    If you just have a skimmer then try to match the flow through the sump with the skimmer pump, perhaps slightly more,
    It makes no sense to whoosh water through the sump to come back into the tank exactly as it left it so it’s a little bit of a balancing act.
    Assuming my maths serves me correctly 60% of 6000 is 3600 so that’s over 15 times tank volume so I would turn it down to 30 or 40% and you should still have plenty of water going through the sump,,,,and save a little bit of leccy, ;)

    Thanks Doug, that is just the Answer I'm looking for! Your maths is spot on! In my three chamber sump I just have my Tunze Doc skimmer 6000,in the sump, I have the drain pipe along with the emergency drain from the weir to the first chamber, from the weir to the sump I have it trickling in. So on your advice I have set the panel control to 45% for the flow,with the power outage reading of 11watts which will save on the leccyAnd of course your right it is a balancing act! I have adjusted the ball valve to the level which is required for ATO Many Thanks Doug
