Today I did a deep clean on the tank. I am still in the process of adding more things but I wanted to upload some pictures real quick. On the left side of the tank is the Monterey Beach Sand. On the right side is something new I wanted to try. It's Aragonite sand in Fiji Pink. A whole 15lb bag is on the right side, so that shows you how little you get in a bag. On the bag it says 0.5-1.0 mm diameter. Emma can you confirm for me that this is the grain size? The pictures show everything dry. I moistened the sand a bit, I like to add it slowly so it doesn't get soaking wet. There's hiawatha moss in the turtle dock with shells. This is with the cardboard divider in. It has been taken out. The crabs will mix it up but I wanted to seperate it when I stuck the different substrates in. I think the color difference is amazing between the two substrates.
