KH is 16 in new saltwater mix?

16?! Whaaat? We have not used IO in years, when we did we were seeing 10 and 13 with IO RC. What are you guys testing with? We use hanna and salifert.

Other salts we used/use

SeaChem Reef Salt 10 (we love this salt)
DD H2 ocean 10


Ray

IO is the reason I switched to seachem. Always had high KH with IO

That would be Salifert Ray. My mix included correct amount of magnesium added and a small calcium boost. Same mix I have been using for yrs. except for a brief try of Seachem Marine salt.

Ah cool, Salifert are very accurate..so yeah, that is a lot of ALK!

Well, most aquarists have to add an alk. supplement. I still use Seachems. So I would guess a slightly higher alk. in ones new salt mix would only assist that during a water change.

The only problem I have ever had was back 10yrs ago when had my 225g and on well water. Used an ro filter but not DI resin, which reduces the alkalinity in hard well water. It interacted with the salt mix and spiked my alk. Took me ages to figure out what the heck was going on.

DOH !!!.
