Staging the area for a 20 long change of black to white sand. 20 lb of sand rinsed, 20 more on the stand by if needed. 8 cups to hold the ladies. 1 cup for what is left of my shrimp. 5 gallon bucket to hold both sponge filters and plants. One bucket to toss old sand...etc.... I changed the 5 gallon tank last month...more or less to see what would be involved. Picture of old here and will add new after its all done.
