I have a 93 gal cube some sps and lps and softies...
my lights r radion g2 at 45% put it up higher the corals start to die.
I have 2 mp10s
1 wp 10 for circulation
cal 440
alk 9
mag at 1500
phospahtes at 5
nitrates at 0
tank is over 2 yrs old transferred everything from my 75 gal that I had for over four yrs and everything was growing and coloring fine. I dose my alk and cal with brs 1.1ml for 4 hrs. don't know y my sps and some zoas are not doing well and sps not coloring. I buy a good coral and has great color after it goes into my tank the color fades away and is dark and then lightens up and the some just die. I also dose bacter clean m as well as red sea reef energy A and B. been dosing it fro about 3 weeks to a month now. I do 20 gal water change every week. run gfo and carbon. I test with red sea test kits. in need of some help to get my sps to grow and color up. don't know what im doing wrong. I know there is something im missing don't know what it is tho. I also dose with brs 2 part. I forgot to add that my alk dosing and cal dosing with my brs pumps only dose for 2 min each hour and the alk I have dose at night. also my lights are 10" off the water line.

    Alkalinity is fine, Calcium is a bit higher than needed, Magnesium is 100ppm too much.
    Phosphate are .5, right? Not actually 5ppm? Salinity is at 1.026sg? What's your average water temperature from day to day?

    Odds are the tank is getting too much light or is running too long. How long is the light period daily? Maybe less white intensity ( % ) and more blue intensity would be better.

    One issue could be the high phosphate level at 5ppm, unless you meant .5 or .05.

    Whoops, sorry, I didn't see Marc had already made the same observation. Also Marc touched on this, but what is your temperature swing during the day meaning the highest temp minus the lowest temp on an average day?

    the phosphate I meant .5 sry guyx fortgot to mention some of this as well. my salinity is at 1.025 my average temp at the most during the day is 78 and at nite the same if not at the lowest 77. as well as I put less wht intensity and more blue. My intensity is at 45% both blues are at 100% wht is at 50% green and red are at 87% and lights are running at 10 hours a day.

    Try reducing the lighting period to 7 hours a day and see if that helps.

    Phosphates at .5 is still high it should be less than .03
    If your nitrates is really 0 then it might be the limiting factor for bacteria to act on phosphates. frequent larger water changes or a phosphate reactor would help.
