KH is 16 in new saltwater mix?

Yep. Just measured my new batch of IO. It was 16dkh

Well glad I switched to reef crystals but I have. Ever had a problem with IO

So is this a bad batch of IO salt or what? Or is IO salt always at 16 for the KH?

Well hard to say. Source water could be at play to I think. But I have had 2 buckets and a bag both reading high 15-17dkh. It's tough to say.

Sorry. I have not measured alk in my mixes for over 6yrs now. I did have some with higher alk between 01 and 05 or around then sometime. Never had a problem with it any time since.

I did a 3g water change on my 20g sps tank yesterday with that 16 dkh mix and not a problem.

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

Doug · #8 03-27-2012, 01:43 PM

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.

Tap w/ prime and mine is sitting steady at 13 atm... I kinda figured it was a bit high, but thought I was just doing something wrong.

ninja edit: With IO

I made up a mix of IO I bought on boxing day, 16DKH. I've been trying to bring mine down, and had my calcium reactor off, test my water at 14ish, do a water change, the next day test at still 14. It was getting frustrating wondering how my tank wasn't bringing it down. Well, after this thread tested a new IO mix, now I know why. Thanks for posting, now I know why i have alk burn on a lot of SPS. My calcium is still high with the DKH, so it seems that the 2 are still balanced in the IO mix, just way too high.

Also, API test kit showed 7DKH the whole time. Took some water into OC and he tested higher, so bought a new salifert test kit that showed 14-16 in my tank. API test right beside it showed 7.

I have to stop "saving" money on my tank, it's getting expensive.
