    Two weeks ago I converted my sump to a DSB, thanks to the advice learnt on the forum. Now I wanted to ask, should I be increasing my water changes for the next six weeks, or continue as usual? I did also add about 10% new LR at the time

    Magman I dont see any use in upping water changes. In my opinion continue as usual. Did you seed your DSB

    Monitor your ammonia and nitrite levels for the next few weeks but i also feel that water changes wont be needed.

    Depends on what you took out of the sump to make space for the DSB.

    If you took all the bio-balls or ceramic rings out and turned that chamber into a DSB and now have none of those balls or rings in the sump, be prepared for a tank crash. You did a heart transplant.

    No problem of having the balls on top of the DSB, will actually help to seed it from bacteria that is on the balls. Then as the bacteria migrate to the DSB remove some balls every week.

    Monitor your params for next 4 weeks.

    Only see now that you done the change two weeks ago, in that case, ensure the params for the next couple of weeks.

    But next time, take it slow.

    Riaan,

    I had a 5 section sump with LR and bio balls, I converted it to DSB in one hit, but placed 25% of the LR on the DSB. There was no other way I could do it except in one hit.

    monitor your parameters - I am sure your tank is going to have a mini cycle, but nothing to stress about - is parameters get worse do the water change early.

    When can we get a pic of this work you have done?

    Just test for Amm and Nitrates, Riaan is a bit OTT but does have a point, However there should have been enough bateria in the water columb for the tank no to cycle again. The New LR may cause an issue only if it was not cured.

    The main concern will be die off from the new live rock and the removal of bacteria with the bio balls but if you continue doing small water changes and watch the ammonia and nitrates you should be fine. Adding a purigen bag can do you no harm either.

    That is ok, and correct thing to do. So you did not loose all your beneficial bacteria.

    is it placed directly on DSB .... maybe you could raise it slightly off the DSB using egg crate or something

    Actually with the LR on the DSB it will help with the seeding process. Less change that the bacteria will be flushed away to the return pump.

    Later on (week 4 onwards), you can start to remove the LR bit by bit, until you have none left on the DSB.

    If you want the LR permanently above the DSB, yes then you have to lift it ontop of some eggcrate. Else use the LR in your display.
