1500 is high. How did it get that way? What salt?

this is my new SPS tank i used IO salt mix and mixed it at 1.025 then i tested everything aside from the mag and alk/calc. where a bit low so i added

for alk: reef carbonate
for calc: reef advantage calcium

tested just today and got:

calc: 420
alk: 8.4 DKH
mag: 1500ppm
PH:8.2

how do i get this down a bit then also in my older softies tank mag is at 1400ppm not as high but a little...

From what I understand, an acceptable Mg level is 3X your Ca level. Not sure at all how to get it down though, without some pretty hefty water changes. Have you been dosing anything that would raise your Mg?

I think you have a test kit failure. IO should come in low. You did use rodi water right?

yes it was all RODI water...huh...ill retest it and see if it reads high still hopefully its not the kit thats bad...just bought it...

What name brand test kit did you get? I'd guess either the kit or one of the additives your putting in there, have you tested before & after adding? Also you should test after several hours or over night after adding.

its a brand new elos kit that i bought today...just went to test it and it read 1500 the reef calcium it has some mag. but not really enough to do that to it i wouldnt thing and if it did the calc. should be way out of wack so maybe i just tested it wrong im going to read the kit a bit and retest... and then ill have barrier test it also on friday see if its a wrong reading...thanks for your input guys
