duganderson Posted January 11, 2013 Share Posted January 11, 2013 I was reading a couple articles on the levels of Calcium, Alk, Mag etc. in salt mixes and many of them including Reef Crytals had lower levels of things like Calcium, Alk, Mag than is recommended in a mixed reef tank? Is this true or am I reading these articles incorrectly? Do folks dose their water before adding it to deal with this? Thanks Quote Link to comment
duganderson Posted January 11, 2013 Author Share Posted January 11, 2013 I just saw this on another forum indicating that Reef Crystals is Calc. 420 Alk. 12Mag.1260 Are these correct. I saw a different post suggesting they were lower. Quote Link to comment

duganderson Posted January 17, 2013 Author Share Posted January 17, 2013 Those numbers were the 3rd post down on this page..... http://www.thereeftank.com/forums/f6/salt-vs-crystals-117151.html Quote Link to comment
SerenityReef Posted January 17, 2013 Share Posted January 17, 2013 Thanks! I'll see if I can find it, I swear I came across an article with levels on 5 or 6 brands at one point. Don't believe it had timed levels... Quote Link to comment
Bill Nye Posted January 20, 2013 Share Posted January 20, 2013 Isn't that alk a little high.... I like my alk at around 8. Quote Link to comment
scribbles Posted January 20, 2013 Share Posted January 20, 2013 All my reading says alk should be ideal around 10, and minimum of 8. Doing a water change today will test the IO reef crystals before I change the water. Quote Link to comment

scribbles Posted January 20, 2013 Share Posted January 20, 2013 Just tested, water out of my storage tank, I mix 25g at a time; it has been circulating about 3 days using rodi, w power head and heater, rodi water tested with TDS meter 0. This is results for IO REEF CRYSTAL SALT 160GAL Temp 77 SG 1.025 CA 560 KH 8 NO3 0 PO 3-4 0 MG 1400 Quote Link to comment
Veng Posted January 20, 2013 Share Posted January 20, 2013 Wow that Ca is crazy high. Quote Link to comment
scribbles Posted January 20, 2013 Share Posted January 20, 2013 tested 3 times all test were consistent, came out with 580, 560, 560, I think I counted a drop wrong the first time I was wondering if the ca is high because the KH is too low, they buffer each other I understand. I’m getting an ethos ca and ph kit next week I will retest with those when I get them. Quote Link to comment
hawkingcolorado Posted November 5, 2018 Share Posted November 5, 2018 Just set up a new 20 g IM peninsula with Reef Crystals. I tested 10Kh and 500 Ca also... Quote Link to comment
