Magnesium really low!

I have been battleing raising my ALK and Calcium and figured that it was do to my low Mg and I was right its at 550 I see epsom is the best way to raise your Mg I was wondering how fast should I raise the levels to where it wont hurt anything.

 

before doing anything I would get that result checked because 550 sounds incredibly low

once you are sure of your exact level
your target for a typical reef set up is somewhere between 1280 and 1350 a bit higher is fine also IME (Maintained 1440 for about 12 months now myself)

the max you want to increase in any 24 hour period is 100ppm

 

I've done 100ppm (300ml) in 24 hours before without issue but I am afraid to do more than that. I use an Kent I.V. doser to drip it. I use E.S.V. - B.R.S. has bulk salts too.

Glad you caught that - 550 is really low! What test kits are you using?

 

I just re-tested and came out with the same results i am using red sea test kit. I have apx. 130 gallons of total volume of water how much epsom salt will it take to raise it 100ppm I have never used epsom salt to raise my Mg

 

the crappy thing is I just recieved my critter package from reef2go aclimating them as we speak, will low Mg hurt critters or does it mainly effect corals?

 

here are my parameters
sal. 1.025
PH 8
ammonia 0
nitrite 0
nitrate 0
calcium 550
KH 6.4
phosphate .06

 

do you mean re tested with same test kit?
what if your problem is not your mag level but your test kit?

2nd opinion before surgery would be my advice

the 3 reef calculator can do the math for you
I checked , and to raise mag by 100ppm in 130 gallons from 550 to 650 would take 17 ounces of Epsom salts

but do not add anything until your 100% certain it is not a dodgy test kit

 

Wait, is your Magnesium 550 or your Calcium 550?

You'd never support a Ca level of 550 with a Mg level also at 550; something is not right here.

 

its a new test kit and I dont have a local fish store that will have a Mg test kit to compare it to. I only can get them online or drive 2and a half hours to a place that would have one

 

I will re test my calcium I do have another kit to compare it to I used hanna digital and it came up with 550 I will test again with a dif. kit I have been adding c-balance every other day to bring my KH and calcium up since they where really low. I just got my Mg test this week.
