    Hi everyone, my supplier emailed me this list of Aragonite he can get, but it comes in different sizes, which do you recommend is best size to use?

    1. Dry Aragonite Seaflor Fiji Pink, 6,8kgs, 18,1kgs (.5-1.0mm)
    2. Flamingo Reef, 6,8kgs (1-2mm)
    3. CoralCaribbean Crushed coral, 9kgs, 18,1kgs (3-6mm)

    Each have their advantage / disadvantage.
    1. Very fine, and you can cause lots of sandstorms if flow is directed downwards, or you have active sandsifters.
    2. Medium, good for sand sifters, and do not stir up too much
    3. Do not stir too much, but can not keep sandsifters, and it can trap detritus if not kept clean. (Either by syphoning or keeping suffucient CUC.

    Gesiggie is right.

    The bigger the pieces, the less chance of being blown around.

    Also what size tank have you got?

    I just got FFC which is very chunky and has a lot of pieces of shell etc.

    I regret not using a bigger substrate in my current tank.

    ive used fiji pink before in a mixed reef or softy diominated system and it was great. a good fine substrate that created a good envirinmnet for micro critters to live in and with the lower flow rate of a softy system didnt fly around that much.

    1-2mm aragonite will be good and heavey and you can have strong flow, plus it will be fine for things like sand sifting goby's or wrasses that live in a sand bed. It will also stay white with decent flow without having to be siphoned.

    Crushed coral i would stay away from. that substrate is too course and will lead to detritus settlement between the particles and thus water quality issues, plus the crushed coral tends to have sharp edges which makes it detrimental for many soft bodied worms or fish that sift through the substrate.

    Go with option 2:)

    Thanks everyone, Option 2 it will be. :thumbup:

    @Ed_Maddocks
    It's a 165L Corner Pentagon tank plus 40L sump. How much do you guys think I will need?

    Again, this depends on your planned stocklist.
    If it is just for "Looks" a 3cm bed in your DT would be sufficient to keep sandsifter gobies.
    If you want to keep sandsifter starfish, sand (tube) anemones or wrasses that like to sleep in sand, you should aim for at least 6 cm deep.

    Thank you @Gesiggie!! I think I will rather go for the deeper option to be safe. Wouldn't want to upset the sand bed and critters at a later stage should I decide to go from shallow to deeper. :)

    i would look at adding 5-7 cm to the tank and bare in mind that things always get moved around so you'll have some areas slightly deeper and some slightly shallower depending on flow patterns and things.

    Just remeber to add water first and sand afterwards....this allows the sand to fall through the water and release any trapped air, if you add dry sand and then water there is always lots of air trapped in the sand bed and thats not good:)
