I'm a real newbie,just set up a 20 gal. long that I had kicking around for years from my freshwater days.Actually the tank has been set up now for close to 2 months.I cycled using a cocktail shrimp and watched it finish after two weeks with my trusty test kit.At first this was just a,"Hey lets see if I can keep some saltwater fish alive".Now after close to $500 into the system i'm rather hooked.lol
Anyway,i recently just went through a diatom explosion.Now I believe i'm into a green hair algae kind of thing.My question is why do all my astrea snails die after about a week?I take the time to add water from the tank to the bag slowly before putting them in the main tank.I know(have read) that snails need a while to adjust.Before they die that get really lathargic and hardly move.
20 gallon long(65 watt Current USA lights and CPR Bakpak 2 skimmer)
Fish and Inverts
1 blue devil Damsal
1 yellow tail Damsal
3 blue legged crabs
1 zebra crab
1 scarlet crab
I had my water parameters checked from the LFS and they matched my test.
Even though I use a hydrometer the SG matched on a refractor.
Is it possible for diatom death to poison snails?
Any help would be great.
