So I was moving rock around because I wanted to clean up my sandbed before Part II of "The Package" arrives this week.
TBS sand is very varied in grain size and has all kinds of shells (pieces and whole), dead coral skeleton, etc. This is great, but in my smaller tank I felt it looked a little out of scale. Better suited for a larger tank. No problem though, just need to rake up the bigger stuff.
I used one of these maintenance tools, using the rake attachment seen in the middle of the far right row.
STEP 1: I turned off powerheads. I left the return pump running. Then I just spent some time calmly and slowly raking the top surface, maybe 1/4" into the sand, doing my best just to grab the larger items, letting the actual sand sift through. I moved all rock to one side of the tank, raking everything into a pile in the front. Then moved all rock to the now clean side and raked the other half into the same pile.
Here's what I ended up with. About 2-3 big handfuls.
STEP 2: Using that same rake, I pushed the pile into a fish net and pulled it out of the water, letting the water drain out and then dumping it into a container. I then borrowed the kitchen colander (shhhhhhh

) that had larger holes and dumped it all in there, over the tank. I could now use my hands to swish everything around in the colander, letting all the sand fall back down onto the sandbed. A few minutes later, this is what I was left with...
Now, this is still great stuff. Lots of surface area. I didn't want to throw it away. If you have a refugium, it would be great for that, either spread out on the bottom, on a sandbed, or piled in a corner. I don't have one, but I do have three "media trays" in my sump that are all empty at the moment. I have some Marine Pure Gems that I was going to eventually put in one of them but haven't yet. So I emptied the colander into one of those, and then placed in the sump first in line. I like that I can view it. Hoping maybe it will be good for pod production???
Meanwhile, I now have a much cleaner-looking sandbed, still with a really nice, natural variety of grain size, tiny shells, etc but what I feel is better scaled to my tank.
