    Hi All

    I see that there are so many different sump designs with so many different methods of filtration.

    What is the best design? How many compartments are required? What kind of filtration should it be?

    Can someone please advise? I would like to add a sump to my tank but have no idea which would be the most efficient.

    Thanx:yeahdude:

    this is a very hard desicion, I myself don't know what route I am going, if you want budget, then I would say dsb, some guys swear by them, if you want sps and have a bit of cash, I would go a monster skimmer and use some reactors.

    There is a lot of variables also, like how much LR you have in the DT, what maintenace regime you want,

    My current build, I am going skimmer sitting on LR, then the second chamber I might use for some mangroves and clay, then the return.

    Its going to be for a basic reef tank. Some LPS, Fish, Softies and Inverts.

    I was thinking overflow into a wet/dry filter with bio-balls, next compartment protein skimmer, next compartment refugium and then final chamber return pump?

    Would that be a solid filtration sump?

    Mechanical, biological, chemical

    so Skimmer first.
    Then DSB / refugium
    Then chemical

    Doubt if refugium on its own will be effective. DSB is better.

    What space do you have for your sump?

    also keeping a spot for RO chamber is not a bad idea.

    Hi Riaan its going to be a 1m sump. That sounds perfect.

    Ill add a DSB in the refugium. Would that be ok?

    I still need to have the tank built so I will ensure I make enough space for the skimmer.

    I think I might go RO as well.

    What is ment by chemical filtration? I am not 100% sure.

    reactors, like in carbon or phosphate reactors

    And that would go in the last chamber? Same as the return pump?

    First get your skimmer, built first chamber just big enough to be able to fit the skimmer.
    Ensure the space above the skimmer, that you can actually lift it out.

    I prefer the space above the DSB to be deep. Mine is 250mm. Others prefer it to be shallow. With 250mm space above the DSB I have plenty of space of refugium above my DSB. But to have that deep area I have my skimmer on a stand. Else it would drown. And for that you have to ensure that there is enough space above the skimmer.

    Return chamber should be big enough to handle at least 2 days water evaporation in case your RO unit decided to stop working because you go away for the weekend. To prevent your return pump from running dry.

    That sounds awesome. I really appreciate your help. Now in a 1 meter tank do you think i will be able to get a protein skimmer, dsb, refugium, phosphate or calcium reactor and ro unit in the sump?

    3 chamber sump easily
    Skimmer
    DSB + Refugium
    Return + reactors.

    4 chamber, or separate bucket or tank for RO. And it might be tight.

    How wide (front to back) will your sump be?

    I also have a 100cm sump.
    1. Skimmer
    2. DSB
    3. Return

    In the return I have a N/P reactor

    In the front over the whole length of the sump I have a RO compartment. This hold around 30 liter of RO water, so I only have to throw in water once a week.

    There must be a picture in my thread.

    Sump will be a standard 90cmx30cmx30cm. I like the 3 chamber sump. After all the reading I did last night I feel confident about it. Do you think that the RO would be suitable to add as well?

    How is that sump working for you? Is it providing optimal filtration. I think I am definitely going to do something like yours.

    The sump looks very tight. How do you get the top off?

    I see the protein skimmer in the first chamber, DSB in the second and what is going on in the 3rd?

    My sump is 100x45x45. 10cm is of the width is used for to RO chamber. So the sump is 100x35x45, i think anything smaller and I would not get the stuff in.

    It's good. Because I have a DSB and N/P reactor it's keeping up easily. Sometimes I think of adding some filter floss to catch some extra waste.

    What do you mean?

    My design looks like this:
    [​IMG]

    The RO is in front of the sump so I can add RO water from the front.

    In the return chamber is a small float switch, pumping RO from the RO chamber into the return.

    3rd chamber had 2 return pumps. Run a remote refugium and cryptic zone as well. The white horizontal PVC is the return from them.

    Plus auto top up.

    Wouter, that looks great. I think I might need to have the sump made a bit bigger so I can accomodate all the equipment. I like your idea.

    The top for the skimmer looks very tight in your thread.

    Sorry to ask this but what is the purpose of a N/P?
