Looking for some light on the matter

[Montaquelaveist]

Hello fellow reefers i need a little help with finding some colorful corals for my tank I'm having trouble with bleaching and slowed growth below are my stats any help would be great thanks to all

tank size 120gal 60"L x 18"D x 22"H

Salinity 36ppt / bet. 1.026 - 1.028
Calcium 435ppm
PH 8.3
Nitrites 0 ppm
Nitrates bet. 0-5 ppm
Ammonia 0 ppm
Magnesium 1410 ppm
Alk 6.1 ( already in the process of raising this )

I currently dose - Iodide, Strontinum & Molybendnum, and Kent trace elements I was also wondering if there is a better trace element that i should be using for the corals

Lighting is a Hamilton CEBU MH/T5 total wattage 670 (4) T5 super atinic bulbs and (2) 14k Metal halides

Any help would be great tired of green :splitspin in my tank :groupflip
look forward to any help

I am by far an expert, but I think salinity is a little high. Also are you testing for what you are dosing.
What is your lighting schedule, and how old are the bulbs.

shouldnt be dosing any of these if you arent testing for them, and no reason to dose them if your doing regular wc's
stability is the key to growth of corals, your alk being too low isnt helping and mag isa little high, salinity i wouldnt ever have higher then 1.026

salinity over 1.026 is a problem.

Thanks for the help i will begin to lower the salinity and as for the dosing i do not test for those but at one point before i stopped dosing and my shrooms and polys stop growing. i do water changes every two weeks 20gal and the lighitng schedule for my lights are super atinics come on @745am and go off @730pm the MH come on @2pm and go off @445pm and only one right now the bulbs are a little over 6months old

Any particular reason for such a short light schedule on the MH?

Didn't know if the tank was getting too much light since i don't have any corals which seem to like that much light most of the corals i have are poly's and zoas the only sps i have are two chalices and one monti and the monti seems to not like it
