Today we prepared the brackish water and put the rocks in. Brackish water is a mix of salt and water. First we took a tip of a spoonful of the decomposer and put in tour jars. Which was something that was black I think. Next we picked a medium size rock from the ground and put it in our jars. After that we filled a empty jar and dumped it in the bucket and did this two times. Then we put a chunk of salt and mixed it with the water. After we filled the hydrometer up to 1.006. And then we poured the leftover bucket of water in our jars half way. Last we put our jars in the garden.
