Have had a brush with diatoms on the sand bed but this evening I noticed a very dark reddish spot on the sand. Then several of them. Got a sample then blew them off and they went away like diatoms. But when I put it under a scope this was NOT what I was expecting. The main "grain" seems to be permeable withe small ciliates (?) around and through it. I did note a few diatoms at about 1:18 (although they do appear 'attached' and very still). Nematode at 1:37. There is also an elongated pale something (in the 2 min time frame) that I thought may be algae but not sure. Magnifications click through from 40 to 100 and 200 as the highest value.
Anyone have any idea what I'm looking at. This isn't sand. I've seen sand and it is solid and you cannot see "through" it.
