    I have 90 kilos oolotic/playsand in my middle sump. I intend doing it on one afternoon, around when I do my water change.

    1. switch return pump off.
    2. siphon the sand out.
    3. sponge down and clean sump properly.
    4. fill the gap/volume left in the sump area with prepared water.
    5. continue with normal water change regime.

    All this would take me less than hour.

    I'm currently dosing Prodibio and been on the NeoZeo method for the last 8-6 weeks respectively.

    Any comments ito 'side effects' in doing it all in one go?

    Anyone perhaps done this in the past, that can share experiences following this?

    Aye man all at once would be a big gamble. Do you feel that the DSB is no longer functioning at all?

    PS did u get my pm?

    even if the dsb is functioning at 30%, what will be in that 30% place?

    First, how old is the DSB?
    When last was it re-seeded?
    How big is it (the footprint) and how big is it compared to your display water volume?

    Remember, it is only the copepods running around that you can see. The rest of the beneficial stuff is bacteria.

    have done it without any hassles in the past... add some stability and microbacter afterwards just to add some bacteria.. with dosing prodibio and running zeo the dsb is pretty much useless in anyway..

    That the reason I'm removing it, its working 'against' the effects of the probiotics....well at least that's the research I've encountered. Otherwise it may take months to sort of cycle its way through the DSB.

    hi Adee just did mine today, took the whole thing out in one shot, i just upped the dose of microbacter (my bacteria strain) to help with the extra load, upped my zeolites from 500gram to a 1kg, so far so good havent feed so bioload should be ok, will test tmr, essentially it will just be like one big water change and the zeolites should handle the ammonia etc

    Hi Wolve, how long was your DSB running?

    What was your nitrate reading before doing this?

    Please let me know if your nitrate reading after this change.

    thanks

    I take it your Zeolites are working well for you then.

    I still have my DSB. Doesnt worry me at all. Ive heard people say that its useless etc. But atleast there will be something to fall back on. And i've just stopped dosing prodibio as i got my ATS up and running and ive seen the effect of it on yours.

    Deon, ironically I've taken my ATS outa action cause I've gone with Probiotics. At the time I noticed that algae growth had receded, to a point it looked as if the algae was dying off and re-entring my system.

    Also after switching the ATS off, I have not noted a recession of SPS colors and visible nutirent indicators has stayed they same. My only problem however is cyno in my frag tank which was there before I switched off the ATS and before i started with probiotics.

    My theory then (within MY system) is that the DSB is working against the effects of prodibio/microbakter, as such not making a dent against the cyno. Also adding a carbon source is only fueling the cyno.

    "they say" that on a new system the DSB would not compete. As mentioned mine has been running for 3 years plus already.

    One more thing (i regard this as bullet proof), yes a pure DSB and ATS system will reduce your nitrate levels and combat nutrient levels... however, my journey into probiotics/zeolites is an experiment to see if i can take things up a notch, in achieving a true ULNS.

    hey Adee some readings i took, my DSB was about 18 months old. not very good results but atleast i dont have too many corals
    but do understand i have a large fish load as well. plus i had a problem with my return pump as one of the fittings broke, so my tank ran for a day with no skimmer and sump :(

    nitrate before removing < 5
    nitrate last night > 100 (havent seen the test kit go that dark ever) :(
    nitrate this morning < 100 (seems to be comming down)
    readin from outlet of reactor < 20 (so the zeolites are doing there thing will be keeping a close eye on things here)

    he he and I carry all the risk of faliure...

    Gonna see if I can make a baffle of sorts and separate the sand and vacuum off a quarter at a time. That way the dsb will still providing some functionality till "the end".
