I tested my last two batches of reef crystals has tested below 1200 and my tank has a 12dkh test reading, just continue to trust IO reef crystals and let the corals adapt or pick a new salt?

What are you using for to check salinity and what is it? When was the last time you calibrated it? Test kits you use for ALK and mag.I tested my last two batches of reef crystals has tested below 1200 and my tank has a 12dkh test reading, just continue to trust IO reef crystals and let the corals adapt or pick a new salt?
Are you mixing the dry salt before you add it to water?

Ah not really, doubt that is the problem because it’s tested that way throughout two bags but I will try mixing it up next WC, thanksAre you mixing the dry salt before you add it to water? (Assuming you're not using an entire bag/bucket at once)
So what you think, change salt or keep RC?FWIW, magnesium in NSW at a sg of 1.025 is only 1212 ppm.
I have no idea if your test is accurate (the RMM method says don’t bother testing magnesium because tests are often quite inaccurate) but raising the salinity will raise magnesium substantially.
I've got 4 200 gallon boxes of reef crystals from a chewy BF deal. alk is testing at 12 I run my tank 8-8.5 I don't like the alk spike during water changes. Any way to bring down the alk...?I’m not a fan of RC for other reasons: metal chelators and vitamins in it. I prefer normal IO.

Thanks all for the info/links, so no way to lower alk without depressing pH...?
I'll buy it from ya, lol!I've got 4 200 gallon boxes of reef crystals from a chewy BF deal. alk is testing at 12 I run my tank 8-8.5 I don't like the alk spike during water changes. Any way to bring down the alk...?
Sure! only 1,100 miles from you though. Shipping costs more than the salt.I'll buy it from ya, lol!
You can lower the alk in the water change bucket then aerate heavily for 12-24 hours to bring back up the pH.Thanks all for the info/links, so no way to lower alk without depressing pH...?
