the inverts and corals are much more sensitive than the fish are, although i'd think the fish would even be showing signs of stress at these levels... sucks that the LFS is responsible...
Mine is Around 1.25....out of the "good" range of my hydrometer.
I think we may be on to something here. Possibly the high salinity combined with a few minute acclimation might explain the issue here.
Eeek! Did the fish store hook the ro/di up knowing it was to copper piping? Fish as others have said are a bit more tolerant. Inverts and corals are much more delicate.
1) Because I'm still new to this and haven't got that far yetwhy not just use regular air line from like an air pump for fish tanks and drip acclimate that way? so you don't have to run back and forth every 5 min. see about that for more details on Dr. Foster and Smith web page. high nitrates didn't kill your snails or corals, not on empact for sure. as of now, the best thing to do is not add anything for a while, at least until you track the killer down. copper does sound like an issue, but it should kill all shrimp, but you said you have one still alive. but there is a toxin in your water for sure, but possibly that shrimp is a hard core and can stand copper. props to his high will to live:headbang2:
Ok people....we need to get a 'good' number here.
Is it 1.25 or 1.025.
If it's 1.25, perhaps it's been topping off with salt water or something?
The problem with letting professionals maintain your tank is that things can happen daily, and they come weekly. You really need to learn all the ins/outs so you can handle the daily grind. Point in case.
Anyway, please verify that specific gravity #.
