Hi hart, can I ask you about this mystery disease?
Did it happen as soon as you added a new clam? Did your last addition die before the others ones did?
it seemed pretty random, if you look at some of the recent threads about vibrant being algaefix, which is toxic to at least some mollusks, now I wonder if there wasn’t a mystery disease at all but my use of vibrant a few times while the system was running…. I didn’t document when I used that product or when the clams died, as I never would have even guessed they could possibly be related so I can’t say for sure.
