I do not think so - look at their website. I do not know any good salt that runs these high numbers. Too high CA precipitates out which is not desirable. This is from the AF website but seems like it it could be your salinity.Yes. Fresh sw have high ca and mag. I’m using aqua forest salt
Well, looks like 35.2 PPT but someone else should check since I am not using specific gravity but PSU. But if I am correct, this is a good value and salinity is not your issue.1.0265 is not crazy high. Right?
Listening to charles delbeek at HTA yesterday was really eye opening, I think low phosphate is your issue. Using the molar ratio formula, 6.5N divided by .02P, times 1.53, puts you at 497.25. Charles showed us slides showing that reefs are anywhere from .8 or so to mid 30s, and our tanks should be around 50-100, so you are pretty high.updates
Monti sentosa colony continue to have small sign of stress. Turning white at a corner. Nothing major yet.
Parameters is ok.
Alk 8.3
Phosphate 0.02 ( not running gfo, just carbon)
Nitrate 6.5
Alk consumption stabilize so far. Now dosing 65ml soda ash daytime and 1.4l kalk at night.
Some early cyano/dinos . Running a small 7w UV.

.1 phosphate would put your ratio at 99.45
I would just be aware if nitrate rises as well. Just make sure to use the formula nitrate divided by phosphate multiplied by 1.53. You want to be below 100, 50 is greatI just measure the tank and it’s at 0.06 . I expect it will increase with heavy feeding and no gfo. I’ll let it ride.
I’ll get the ICP in a couple of days. Hopefully it will shed some light into the issues.
I don’t disagree . But I had same issues when my phosphate is ard 0.2. I only addef gfo temporary to bring it down. Is there a target range i should shoot for? 0.02 is too low, 0.2 too high?I don’t think your issue is water quality, but if it is the most likely culprit is the low (or zero) po4, like @Alexander1312 already mentioned. This is known to be problematic, and the only real red flag on your ICP. Iodine low and zinc high raises an eyebrow but I doubt it’s causing harm. I’ve had a lot uglier ICPs than this with happy growing corals.
Some funky bacterial stuff or pest or pathogen is probably the most likely, but I know that isn’t helpful at all!
I don't think they need to be that low, trying to keep them that low can create issues. Kenny from high tide has several vidoes on utube where he mentions his thoughts on lower nutrients. Not any expert advicd here. Yet I wouldn't be considering gfo at all if i was at 0.2.This is from BRS:
For most reef tanks that are no more than 2-3 years old, phosphate levels should be kept very low in order to avoid problems. You’ll find recommendations ranging from 0.02 to 0.05 ppm are the most common answer.
I’m still learning and gaining experience, but from what I have heard:This is from BRS:

Phosphate (and nitrate) is something I find very hard to hit any number range. It’s hard to know the tank consumption and how much you’re adding from food.
