Well, they dig down and disappear, but they just sit in the same spot. I can see their nose thing sticking out. I only have a few, but my sand still gets all "dirty" if I don't manually stir it up.
I am having similar issues.
54 gallon...60 lbs of LR...
I have 12 turbo's...50 blue legs...and 8 nessarius snails.
But just can't seem to keep the sand "clean" as I would think it should be.
Any input would be appreciated.
Is there any downfalls to using a UV Sterilizer in my reef tank???
