Algae is starting to get to be a pain. Would like to get another cleaner package but my last one from Saltwaterfish.com has only 2 Astrea Snails left. 18 Astrea Snails, 25 Blue Legs, 20 Red legs, 2 green crabs, camel shrimp, 7 Turbo Snails are ALL DEAD!
I purchased the biggest Red Hermit crab I have ever seen, 3" out of the shell. He lasted one night. Saw him running out of his shell across the sand before going to bed. After the big red hermit died off I realized half of the Invert package was gone so I took out the eel. I used to have a Snowflake Eel in but figured he was the one eating the Crabs so I put him in my other tank.
175 Gallon Tank inhabitants: 4" Juv. Emporer; 7" Naso; 3" Cinnammon Clown; 3" Bi-color Angel; 2 Blue Damsels.
The remainging cleaner package slowly died off. Just recently tried to put a Mexican Turbo Snail in, he lasted about 4 days.
Does anyone have any Idea why they all keep dying? My two remaining Astrea snails have been in there about 6 months.
Tank Chemistry: PH=8.2; Ammonia=0; Nitrites=0; NITRATES= 50 PPM; Calcium=?; Phosphates=?;
Any help would be greatly appreciated.

What is your water source? Have you ever used a copper based medication in that tank? Snails and crustaceans can have problems in a tank with low calcium and/or iodine. I think I would check my tank for copper and Calcium. Copper is fatal to inverts.

Also, keep a close eye on your salinity. That could be fluctuating quite a bit with evaporation, top offs, etc. Inverts are sensitive to quick and/or drastic changes in salinity.

With the hermit running out of its shell, i would say it would be to some sort of heavy metal poisoning, most likely copper.

And, your nitrates are kind of high. 50ppm is up there in the caution zone. You may want to try to bring them down as well...
