All inverts dead! HELP!

My water quality is fine. I even had the fish store test it and everything is perfect. However I cannot for the life of me keep any invertebrates alive, i.e. starfish, urchins, snails, sponges, etc. All of these things die in my tank! Especially starfish. Now the troopers of the tank, snails, are dead too. Does anyone out there have an answer? I am down to sand, rock hermite crabs, and fish. None of the fish or the eel seem to be affected.
:mad: :notsure:

When you said all of your parameters are fine, which ones???? Copper can whipe out your invertabrates and leave your fish OK. It can get in ther by just using water from your tap that has copper pipes. Another thing might be some sort of sprays or chemicals that are used in the room, or are in the air. Seems like I just read about a dentist office having these sort of problems.

Ph is 8.0
Salinity 1.025
Calcium 450
Temp 79
Nitrite 0
Nitrate 0
Ammonia 0
around 2 - 3 watts per gallon
Tank is 5+/- months old
I do not have a test for copper. I also use R/O water so I should not be getting any copper. Is light an issue with inverts?

On another board, the same problem resulted in a copper test which turned out positive. Copper will kill inverts fast.

You should also be testing your alkalinity.
Your lighting may leave a bit to be desired if you are deciding to go with coral or anemones.

The LFS said my alkalinity was fine. I guess that leaves copper huh. Where would the copper be coming from if I am using R/O & DI water for my changes?

How long do they last befor they die. Could be acclimateing them wrong or do you have fish that maybe killing them like puffers or hawkfish ?

A piece of wire from when you were doing your electrical???? Don't know. It might be worth getting a test kit for though. Its about 6 snails worth.

Copper can come from like what claw said...could be something in the tank?
Another great point brought up was acclimation...they need acclimation same as a fish might, though many skip this and they are fine. I acclimate everything for at least an hour regardless just to be safe.
Good luck, hope we are helping you diagnose

Yeah, we need a time frame here.
For example, if your seastars, urchins, snails, etc died within several days, then I would say acclimation (how do you typically acclimate?). Seastars, keep in mind, are INCREDIBLY sensitive and need long acclimations...what color and kind were you trying? Your tank may simply be too young for many.
If everything dies...including that you don't see much in the way of hitch hikers like copepods, amphipods, worms, etc. then I would consider some sort of heavy metal situation (Don't have any brass fittings, stainless clamps, etc?). Also check the water coming from the RO for copper.
When you mention the snails dying, do empty shells just turn up, or do you see them on their backs, almost paralyzed?

It depends really! Most of the Seastars only last around 1-2 weeks. The snail situation is different though. They have been around a while and now all I have are empty shells. I do have stainless hose clamps but they are not exposed to the water. The seastar situation could very well be improper acclimation; I'm not sure though! I haven't seen any hitch hikers either, and I have 185lbs of live rock! I ordered a copper test kit. Hopefully that will give me a better idea. I thought maybe mantis shrimp. What do you think?
:notsure:
