Vals are prone to melting with changes in the water. This is most commonly seen when people start/stop dosing Excel. Have you changed anything? Has your water change routine been altered at all?

They like to drink up your carbonate hardness, what's your kH? Has your pH dropped significantly (a sign that the kH is gone/going down).
