Please Help with my snails and corals

[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?

the plastic container I bought it from a lfs brand new. my water ph after mix is 8.4 and very steady.

Have you used any medications in your tank in the time that it has been running? Nitrate of 5 isn't through the roof but it is a little high in my opinion.

I didn't put copper or any other meds in my tank. All my fishes and two cleaner shrimps r alive.

I placed a poly pad in my filter for a week now. There is no colour change on it at all. No copper or heavy metals i suppose?

One of my friend told me that I don't need a canister filter in a reef tank. Should I remove mine?

I brought my water to a lfs again this week and it showed that my mg is 600. She checked it twice with two different test kit(elso and something else) but my cal and ak level r both steady. 420 and 8kh. I have added mag in hoping to bring it back up. My phosphate-0, copper-0, all other readings r perfect.

All snails and corals r dying in my tank in one/two days. What else can I do now. If there r something so toxic that can kill em in 2 days, why r my shrimps, fishes and hermit crabs doing so well?

Please help.

What do you currently do for water changes? Were the coral and snails that you bought well established and healthy at the store? Overall how much flow do you have in your tank? Do you have a protein skimmer?

I'd remove the canister filter.
