    I am in the process of designing my sump and would like your opinion on LR in the Sump.

    I have quite a bit Of LR and i am not going to be utilizing a DSB, so i want to have the denitrifing of the LR do it. water will be prefiltered with the same material that the current filter socks that we have in the country are made of, and then skimmer Bubble Blaster 5000 in a 455L tank (so really overkill). Tank will be BB with not lotsa live rock in display, i also have 2 seios M820's that i can put in the sump to keep the detritus in suspension.

    Your thoughts?

    It will work, the only downside is usually the accumulation of detritus and the restricted space to siphon it out regularly, but if you say you'll put some pumps in the sump to prevent that then I don't see any problems.

    I'm going to differ with Tobes on that. Firstly, what do you need LR inthe sump for? Water delivery to the lower, anaerobic regions of your sump is most important. Fair enough, there are different regions with different types of bacteria in the sump, but I think the overall idea should be to let it stratify into levels across the whole area of the sump to maximise the denitrifying potential. By placing objects onto the sand, you create dead zones under them, where there are no critters facillitating water diffusion.

    IMO you shouldn't interfere to much with the natural order of things by trying to keep the sump clear of detritus settlement. Afterall the inhabitants of the sump need food too.

    Hi Mudshark

    I am not going to have a DSB, and there will be very little LR in the display tank as i want an open looking tank. LR in the sump will be for denitrication

    I wouldn't have said that if he had a DSB.
    Now stop thinking about the coming weekend...

    I regret going with a dsb, if I ever move the DT so that I can get to the sump, the sand is going and I will fill it with 300kg LR and the skimmer only. I think for softies and LPS there is nothing wrong with it, if anything I rekon nitrates help softies to grow,

    If you were going sps route, then I would say DSB.

    Just my opionion

    If you are going sps I would say no dsb or live rock in the sump and just the zeo reactor but thats just my opinion...

    the issue with Zeo is there is just too much labour involved

    Ziyaad, not really bro. All you do daily is, pump your reactor and dose your bacteria daily.

    I thought zeo would be hard work. Every night I dose bacteria and vodka, give my reactor a few pumps and all is sorted. Takes like 30 seconds. It is when you start dosing all the other stuff like potassium and iron, then it gets time consuming. Having said that all the brightwell products can be mixed together before and then you just dose say 1ml of the liquid and that contains all the additives you need.

    My answer on the original question

    What is the price difference between LR and a DSB?

    Say 40kg of LR, compared to 80kg of playsand?

    hmmmm.

    Why put stuff you paid $$$ for away in the sump, use them in the display...

    well, my thoughts are keep it simple, yet most effective. LR might trap detritus, and a DSB is a pain to take out once you need to 'move'. And what is the real difference in benefits between the two?

    I wouldnt always suggest bacteria dosing. Its not for every system..
