Problem - for the last month my snails have been dying. Probably 50% in the first week, the rest (mostly the larger ones) dying off slowly after that.
ph - 8.2
alk - med to high (no exact #)
temp 82-83 (fan recently burned out raising temp from 81)
salinity - 1.024
tank age - 3 years +, 180 gal, 55 gal sump
water well water through ro/di
live rock - 250 lbs (all 2 years old or more)
4 inch sand bed
Only additive I ever use is Wages Lime in the top off water
What Ive noticed -
All this seemed to happen after I rid the sump of all caulerpa. I still have sea grass and cheato growing in the sump. Could be coincidental. Pods are still present.
I dont remember the timeframe, but recently stirred the sand bed in a few places and saw some darkened (almost black) sand come up. Covered those places back up.
Smallest snails (2-4mm), little guys that came on the Florida live rock seem unaffected.
Nassarius snails seem unaffected
Cerith, astrea, conch, turbo - dead
Starfish, all fine (maybe slightly less active?)
crabs, all fine
fish all fine
corals all fine
Clam - starting to not open quite as full
Ran phosphate remover for 7 days, performed 2 - 20 gallon water changes and a 40 gallon change over 3 weekend periods.
