Please Help with my snails and corals

[kenman999]

Recently I have added a torch coral, xenia and 2 giant turbo snails to my 60 gallon tank. Everything was dripped for 3 hours before I place them into my tank. Everything was open and alive within the 3 hours. However as soon as I place my corals and snails into the tank, the torch and xenia changed to a dull blue colour and the torch started to spit out some white mucus. The snail went inside its shell not moving at all. After 24 hours the snail was still in the same spot. I picked it up and it smells fine. The torch was still shrunk and dull blue. After 2 days the snail died and my xenia died too.

My tank is 4 months old with 50lb of liverock with livesand

water parameter(I use RO water)
ph-8.4
nitrite-0
nitrate-5
ammonia-0
copper-0
calcium-420
phosphate-0
salinity-1.024( with instant ocean salt, tested by a refractometer)
kH-9
temp-78

I use APi test kit and I have brought my water to two LFS and both results are the same.

I have 6 t5 blub, 4 day light and 2 aqua blue+ turned on 8 hours a day.

Torch on my sand bed with moderate water flow.

Fishes- 2 clownfish, 1 firefish, 1 yellow tang, 1 scooter blenny, 2 cleaner shrimps. All doing perfectly fine for 3 months.

Why are all the coral and snails dying? Please HELP Thank You.

1 hour would have been fine and also did you have a heater in the pail cuz they could have been shocked from the sudden temp change

Are you running carbon at all? seems odd iff everything else is doing fine, but there may be some biological warfare going on that carbon might be able to pick up.

Temp change is a big one too, hound is right with that.

I am running carbon in my tank.

When I acclimated my corals, the plastic container was in the tank. So that should solve the temp change?

I bought a poly pad last week and it showed no colour change on the pad either.

staying on the topic on acclimation how did you go about the drip process???

[kenman999]

First I place the corals inside the bag floated it in my DT for 30 minutes. Then I place some water from the bag and coral inside the plastic container and place it in my tank. I got a bucket and placed some DT water in and located it to a high level. I started dripping it at a rate 2 drops per second. When the plastic container was full I threw away half of the water. Repeated for 2 hours, I placed the coral in my DT and threw the water away.

ok good that what is was getting at lol if you dont have it in your tank then over the few hours it goes cold.

any possibility you have a hitch hiker crab of some sorts or something similar??? maybe search around your tank during night time to see

[kenman999]

i have placed different corals and snails in at different times. I look at my tank all the time at night, I don't think I do have any hitch hiker. The corals and snails looks pretty dead as soon as I put the in the tank.

Possible the plastic container was used for something else before hand? Did you get em from a store? Or another reefer.... Bag contaminated maybe? Im not familiar with Vancouvers water, here Id have to do some serious work to hit a ph of 8.4.... Are you doing anything to get it that high?
