Why the hell do my sps keep dying

[dabandit]

all sps were given 12'' away from any other coral

[dabandit]

Im stumped I've tried on and off to keep sps for about 2 years allways the same result but only in this system,could it be parasite or bacteria? and what can I do?
P.s no cyano i system but some hair algae on back wall for tang

Check your REDOX potential

Alk at 10 is way to high with the zeo system. 8 is the highest it should be.

[justinl]

how old is the system? I admit I am not familiar with zeo, so here's me dropping out of the conversation

SG of 1.022? How was it measured?

[Red Coral Aquariums]

The only things that jump out at me on your parameters is the low salinity (I would recommend 1.025 or 26 and due to the fact you have not tested for Mag. Here is an article that might help.

[o.c.d.]

when you are adding the corals are you starting low in the tank? how about the age of the bulbs?

[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......?
