Good to know that this will go away on it's own.
I did purchase a ro/di unit to fill the tank, use for water top-offs, and water changes. I am pretty sure the sand I used was aragonite, but would have to go back to the lfs to check on that as I used it all.
It's good to know that I should not be too worried about it either, though it sure is an eyesore; especially on the bright white sand.
In any event, it's still a good excuse to get a cleanup crew started as I am lacking that. This just gave me the kick in the rear end to get it done.
So, as suggested, I picked up some turbos and nassarius snails. At the last minute, I pulled back from the crabs. I've got an iphone app (pocket reef) that claimed the scarlet hermit crab did not exhibit shell envy. At the lsf I decided to think about the logic behind one crab of the same class not having the shell envy issue ... it did not sit well, hence I canned the idea. Was planning to ask here about that, but you answered that for me :)
Anyway, for everyone else, that pocket reef app is nice and helpful, but there are small inaccuracies like the one with the scarlet hermit crab.
I might try to get that silicates tested on Monday just to rule that out. However, not many tests for that come to mind, which might force me to pickup a kit. Should probably purchase my own refractometer too as opposed to using the one at work...
Anyway, I am rambling. Thanks for the help once again :)
