Why the hell do my sps keep dying

[mark]

With a Ca of 450, chances Mg is okay (from a observation with low Mg, I'm unable to get my Ca up).

Source water?

Ok where do I start;I dont dose ka,flow also comes from sump return at some astronomical rate,they are dying bottom up,i use 2 decent hydrometers and reference both for acuracy,I cant find a mag test kit at any lfs ive checked so far but i assume its okay because my calc and ka are high?,system is approx 2 years old,i dont keep softies anymore,i have'nt seen any bugs or what not even at night and yes I aclimate properlly but i dont use any products in doing so,no I cant even keep monti ALL sps species have died

So heres what I've got from you guys so far;slowlly raise salinity,bigger koralia......?

oh and source is ro di

I am not sure why everyone thinks that 1.022 is too low for SG reading. Myself and a few of my friends all keep our SG at 1.022 in my SPS reef and I have never had a problem. I know a LFS here that keeps it at close to the same level as I do as well.
Can anyone fill me in?

It's not that 1.022 is low for a system; i don't personally see a problem with that. The problem I see is that if a coral (or anything really) comes from the majority of the stores who keep their water at 1.025 (notice i said "most" this time ) it has to very quickly adapt to 1.022... essentially its getting the salts sucked out of it by osmosis. Even with proper acclimation for hours, I don't know... but hey, that might not even be *the* problem.

So I couldn't find where you mentioned the Temp of your tank. High and low or if it is constant. Also are your corals bleaching? or do you notice a brown jelly, white paste? black gooey material? ect..
I ask where you place your new coral and bulb age because of burning. If you get your corals from the same place, that happens to have low light and the tranfer to your tank with bright light, now where in the tank may be safe from burning esp if your tank depth is low and your lights are close to the water. Just a thought.

I still say if you go to the Zeovit.com web site and say that your Alk is 10, they will tell you to get it down to NSW readings. It has to do with the way the bacteria work in the zeo system.
