all of my corals are closing up or dying. I am not sure if it is a water chemistry or lighting issue. I have 3 Hyrda 26’s over my 125. My latest parameters were Alk 9.35 Calcium 440 ppm Mag 1285mg

It has been a slow decline, I changed my light settings in hopes of correcting the issue.Is this a sudden event?
Light shouldn't do that unless it was changed recently or the it was a slow decline.
Kinda the same for chemistry.

True.Post all your water parameters - or everyone will simply ask you for them. Like PH, Phosphate, s.g. value @ what temp? You last WC, did you use RODI water, and which brand of salt and what % of total volume was changed. Etc...
Along the lines of WCs can't hurt - I did multiple daily 50% WCs with RODI water, instead of tap water. About 9 days later my phosphates level would stay below 0.10 after two days.
When my tank was going south, my phosphates were too high, past 1ppm at one point.
If 3ppm of phosphate, then wow, I assume an expert-level tank with critters that like those params, not at all in my league.Not .3 but 3.0.
I just checked all of my parameters befor I left for work today. Alk 9.07 Cal 529 ppm PH 8.1 Phosphate 0.00. I am not running GFO but I have been dosing NOPOX since the tank was setup. My last water change was Tuesday, 30gal I use Instant Ocean Reef Crystals. SG 1.025 temp 79 degrees F.Post all your water parameters - or everyone will simply ask you for them.

I would halt the nopox, more than likely it's a nutrient issue. If your po4 and no3 (My guess is they are undetectable?) your corals are starving if your nutrients have been low for a while.I just checked all of my parameters befor I left for work today.

I'd be curious to read a write-up on those types of tanks.
He's made good improvements too. Got the po down to under 2.7.Was sitting down... couldn't get up anytime soon. OMG ;Jawdrop now I look at my tank ;Shy
Lots of SW forums out there - real glad I started here.
