Inverts Dying When Introduced into New System

[AmpWin1]

Good Morning - please assist:

I have tried twice now to introduce a few inverts (sea cucumber, bumblebee snail, red/blue legs) from my 29 Gallon - high nitrate tank into my new 95 Gallon set-up with low nitrate, no copper, triple filtered fish only system. I have acclimated for hours for both temp and water. Long story short - when these inverts go into the new tank, they die or get sick almost immediately. What am I up against here - I have tested for copper, nitrates, nitrites, phosphates ... the fish do great in there - but a few simple inverts die on contact. What I am I not thinking of?

Thanks for the help.

Stupid question but how are you acclimating them? I've noticed the same problem in the past and traced it to how the inverts were acclimated. Some inverts like Urchins and some crabs do fine with adding 1/2 cup saltwater every 30 mins, but inverts with softer exposed tissues (ones I can only presume hold more of their mass in water content) snails, some hermits, stars, cucumbers, etc REQUIRE a drip acclimation, running some airling tubing with either a valve on one end or a knotted kink. If you are doing this kudos and I have no clue what could be causing this.

If you are not doing this, get that drip acclimation going at a rate of 1 drop a second into the bag containing the new inverts, when the bag is full empty out half the water and continue the acclimation until the bag is full once more, then add to your aquarium with lights off for the day and they should acclimate well.

If this helps cool, if its no brainer stuff that you already do, sorry I couldn't be of more help Good luck! Let us know

Thanks for the quick reply - my acclimation currently is not a drip method - however, it may quickly become one with your suggestions. Thanks!

salinity way off?? temp?? contaminant somewhere??
