Oh Home Depot.

Pictured here is a bag of time saving play sand

     ALERT If you don't like long stories you can read the words in blue and get a succinct update. Home Depot to the rescue. I did some research and realized I could use "play sand" as my sediment. So I spent about an hour driving to and looking through Home Depot for a bag of play sand. I literally looked up and down nearly every aisle to include the entire garden section for play sand until I resorted to finding an employee to ask about the location of it. Once again, I looked up and down every aisle to find an employee to ask about the location of the ever elusive bag of sand that was going to save me an enormous amount of time. I wrestled with interrupting the customer service employees who were balancing a line of people, literally out the door, as my impatience grew. Until I saw this really cool impact wrench display and my mind wandered to NASCAR for some reason, good lord that tool was a beauty, I envisioned myself  replacing my wheels on my car in pit crew speeds. Wow what a tool! Until I came to and saw a glimpse of a "under cover" security guard in my peripheral. Instead of asking him for help, I finally saw a Home Depot employee, he was kind of in a weird viewing angle of me, kind of in a hunters angle trying to kill prey with that side eye look of observation,  at the exact moment I thought nothing of it, I started hustling his direction, as I closed ground his silhouette disappeared, by the time I made it to his perch he vanished. Crap! Fast forward I found a home depot employee and was told the play sand was right next to the Drywall and lumber. In my very basic understanding of construction I don't see what they have in common but hey play sand and burning calories have a lot in common and I am sure I put in a half marathon finding that sand. Anyway I found the sand, 50 pounds of it to be exact. As I lowered the sand into the cart, gave it a playful tap, and played the triumphant trumpet tune in my head I noticed the under cover employee and the disappearing home depot agent were flanked at each end of the aisles. Being in the lumber area of the store diminished their cover. In between each long piece of lumber daylight reveled their positions. Here I am lost, looking for help and two gentlemen with those wannabe secret service "hidden" ear walkie talkies are following me everywhere. So I accepted their challenge and took extra laps around the store seeing if I could lose them or catch up to them. And I caught up to the under cover dude, (the strategy I used was super dope.)  I asked him where the impact wrenches were and insisted that he walk me to them. From there I bought the sand I came back to the school. I repeated the process to retain sediment. I was super optimistic this sand would cut down on the amount of time tremendously. This Time my retention rate was about 90 percent retention! I will have enough useable sediment to use after just an hour worth of labor. Pretty sure I will have an experiment under way this coming week.

The play sand is on the left, this is what I retrieved after one hour.
The one on the right is the sediment from various phoenix sources, what I retrieved over weeks.
