    Hey guy! So I was looking for my one power head, but couldn't find It! So I looked In the cabinet were my old corner tank use to be on and found that I never got rid of the sump that was still full of live sand and salt water.

    The tank was without water circulation for months (2 and a half, maybe 3) and only got about 4 hours of natural sunlight in the mornings (back part of cabinet is open).

    I have found a few things still living In there! There Is a Pistol shrimp, a purple looking snail (I think It might be coralline algae growing on the snail), millions of feather dusters, Halimeda and Caulerpa filiformis. Oh! And I saw a copepod.

    Class Is clean, water Is clean and the water smells normal.

    I'm thinking of using the sand again but I'd rather not take the risk and crash my new tank.

    Oh! And Is the Halimeda and Caulerpa filiformis save to use In my new tank?

    usable if you reuse the sump as is.

    Else if you need to transfer the sand, then you need to siphon the top 2 to 3 cm sand into another bucket. Then move the next 50% into yet another bucket. Then move the bottom layer to new sump, Refill in reverse. The idea is to move it in layers, keeping each layer at the depth it was.

    Do not have your circulation in the new sump on while doing this.

    Let it be for a day or two.

    siphon excess settlement that might be on the sand off.

    Test ammonia, if acceptable then you can place a couple of hermits on the sand to help cleaning it.

    You will loose the feathers, pity, unless you can move some over that is on equipment.

    i would use as is if possible but i would start by only circulating a small amount of water through it at first increasing it over time to ensure it acclimatises to your main system, you dont want to crash the system due to a dramatic change in values..

    nice find...

    I'm going to leave the sand in the sump, add circulation to the water and slowly do water changes. Onse the parameters are spot on then I'll see If I can en corporate it to my new tank.

    I wonder were the food came from to support the survival of these animals. This reminds me of those self sustainable ecosystems.
