I'm not sure, maybe I'll test my new water tomorrow and see what the numbers are.

I'd would retest the dKH....
I retested 4x. All came up right around 6.1°
It time for the veterans to chip in...based on the readings I'd continue WC and try to raise the dHK.
Alright thanks!
The high calcium and mag is from the rc salt. The levels aren't normally quite that high but close, the rest is probably test kit noise. With that said, you will always see alk lower much faster because there is MUCH less alk in the water compared to the other two elements. For every dkh alk used about 7ppm of calcium is used. This small calcium drop is much harder to see with a kit.
Fyi, my tank uses over a dkh of alk a day.
My old tank was like that but that's when I was packed with corals. I have mostly zoas now
Other things will use up alk... phosphate remover, new sand, coralline algae etc.
Well maybe that's why, my coralline is growing like crazy. And I did start using phosguard so it makes sense now
Keep a closer eye on alk, than the other two and adjust slowly as needed. New tanks take more attention.
Gotcha, will do. Thanks man!
Okay I haven't been able to test my freshly made water yet, been a little busy but I've been thinking. Could my calcium be that high bc I threw a few dead SPS mini colonies into my fuge?
nope, not unless your PH is in the low 6's like a calcium reactor.
Okay well then that's off the table Lol
Just tested my fresh water and I think its time to switch salts. Here's my results
calc 620ppm
Alk 8.4°
Mag 1760ppm!!!!
Like seriously? It never used to be this way. Do you guys think its a bad batch of salt?

When was the last time you calibrated your refractometer?
Not too long ago. I can recheck it tho.
I would
Alright now things are making more sense. My refractometer was off by 5ppt. So my salinity is actually 1.030 :/
That explains the high calc and mag but still not sure on the low Alk level. My tank tested out at 4.6° just now. That's insanely low
