I have had a few snails and hermits "drop dead" since this crap came about, so this is definately possible. There are still many, many of them. I have tons of assorted hermits and snails still. The TDS is testing very low. Phosphates and silicates were tested by two LFS this week and are not present. I was told that they have "never seen better water"
