    Hey reefers

    Ive been considering changing my sand bed in DT. I really dig the sugar fine aragonite.
    Just looks more natural.

    How would one go about changing it in an established tank?

    Im thinkin, siphon some out with each waterchange until half is out, then add the new sand halfway. and do the other half also over a period of time, as not to shock the system.

    Let me know your thoughts

    Thanks

    I would do it more slowly than quickly, when I changed mine over I changed a quarter every two weeks.

    Took out a quarter did partial water change, added new quarter did the rest of the water change.

    i recently did this... removed 50kg of aragonite and replaced it with 20kg sugar fine...

    syphones it out all in one go... did a 300lt waterchange and my substrate looks fantastic.. zero losses

    had to clean my skimmer out a little more often the firts week and although i dident, i would recomend you use a product such as stability to assist with any mini cycle that may occur...

    Is it a DSB in the display or just for aesthetics?

    If it is the latter I cannot see why you could not do it in one go.

    A bit of a warning sugar fine aragonite in a Boyu can be a nightmare. I am considering getting rid of mine as it is constantly moving from the flow of 1 mp10. I can have it running for weeks with no disturbance to the substrate then suddenly over night it has gone crazy and a fine layer will have landed on all my LR. The sand on the LR then needs to be scrubbed off or it will get a blanket of algae on it in a few days.

    You can siphon out sand with your water change. About 20% per week.
    When done, you can add the new substrate.
    Depending on your other biological filtration capabilities, life rock, DSB, NP-Pellets, Orco Cubes, Refugium or whatever you employ, this would allow the bacterial colony enough time to adjust.

    I also had sugar fine and it's a pain in the ..... if you run sps and have lots of flow the stuff goes everywhere!!

    in my new tank I have large crushed coral and if I wanted to now I would add sugar fine so it get into the crushed coral and does not move around as much.

    good luck

    I thought this would be detrimental to your tank, as you are removing a big part of your biological component of your tank? Agree with @RiaanP, do it partially.

    Great stuff guys, thanks for the input:thumbup:

    I will be doing it slowly as stated initially, rather safe than sorry.
    As for the sand storms, im running a LPS / softy tank so dont think it will become a problem.
    Have a few sps frags but not really gonna go much further into it.
    I like the movement of corals more;)

    It would be if he is talking about an in-tank DSB - if it is just a thinnish layer for aesthetics rather than a DSB there should be no issues.

    It runs on full. It creates sand storms already and I still want to add another mp10 as 1 doesn't provide enough flow for sps. I know the sand needs to go if I add another.
