Snails very unhappy

[nlreefguy]

This has hapened to me in the past, almost always associated with large or sudden shifts in pH and/or alkalinity. Yes, I've been dumb enough to let it happen more than once. I lost a lot of snails once when I started dosing kalk, in probably too large volumes at once and again when I added too much alaklinity to my top off water over a period of a couple of weeks (when I tested the alk it was 17).

Mitch: Usually my pulsing xenia, purple xenia and one of my pocci colonies are the first to display signs of displeasure if there is something going on in the tank, no matter how minor. Their behaviour is now pretty predictable (tends to happen after watching the tank for hundreds of days); I can pretty much tell you the pH based on what my xenia is doing.

Today, things aren't looking as bad as they have over the past while. The Strawberry Top is finally sticking back onto the glass though is still looking a bit rough (hadn't come out of his shell in a few days) and I found nassarius eggs on the glass this morning (they have a pretty distinct pattern), though I have yet to see the cerith perk up (if they survived). We'll have to wait and see...

I suspect that as your system stabilizes, the problems will settle down.
