Here is some of the life in my dsb. Again 90% of the life is in the top layer with larger grain size. Really upsetting I went through all that trouble to find oolitic just to see 2 worms in it. :-( when I move I might try a second fuge with all large particles and see the difference. Shimek was pretty strong on oolitic supporting the greatest variety of life. But I'm not seeing it.
