kh through the roof

Its always a good idea to at least test everything when you first open a new bucket.
That way you pretty much know what you got.
 
Mix up a few gals with the new salt and test it. The problem with ReefCrystals was a year or so ago (maybe even longer), some of the batches had low calcium. Some batches were lower in ca than Instant Ocean.
 
i mixed up a new batch of reef crystals using r/o and did a 10 gallon water change my dkh has come down to 15 and magnesium droped to 1100 from 1300 my alkalinity went from 7 to five and calcium droped to 420 from 450 so it looks like its more water changes -i have always used reef crystals and had no problems
 
i always test the water from the shop i buy from and and the salt mix is always the same 420 calcium and no nitrates or phosphates thats why i have used them since i began marines
 
i use ready mixed salt from my marine shop the calcium levels are 420

i mixed up a new batch of reef crystals using r/o...i have always used reef crystals and had no problems

i always test the water from the shop i buy from and and the salt mix is always the same 420 calcium and no nitrates or phosphates thats why i have used them since i began marines
I'm confused...lol
Do you buy premixed saltwater or do you use Reef Crystals? Or little of both?

you also say that they "dropped" but the numbers you posted all indicate a rise in the levels
