magnesium levels

[mario4254]

so i just checked my magnesium levels and the test (elos) showed 1150 thats low water change was done few days ago my salt is reef crystals so my question is what do you use to raise your levels and what can i add to mantain levels ones i get them to right level ..........so far i been using kent stuff in the green bottle i provided i pic so you can see what i been using im not sure if its the right stuff since on the bottle it say : strontium&molybdenum thanks for anyinfo

I use Brightwell Aquatics Magnesium supplement when needed. I don't think the brand makes much of a difference, just dose when you get low. Magnesium is important, it makes your calcium available to the corals. Test once a week once you get it back up to 1275-1300, you will get a feel as to how much you need to dose after a couple of weeks.

The magnesium level in new Reef Crystals salt is only 1260 to start.

Here is a link to the big 3 elements...calc, alk,mag.. in all of the salt mixes.......Thanks to BillyBeau1

Agreed, my new bucket of RC opened over the weekend mixed up to 1240. I use Randy's DIY 2 part as well as the magnesium. I mix up 5 gallons of water at a time and i need 65ml of the magnesium additive to make the water 1400ppm. I keep my tank at 1400 by dosing 5ml of the additive two times per day (10ml total). My magnesium level is rock solid the way I am doing things right now. However, if I add a couple more acros (like I am this weekend!), i may have to adjust my daily dosing.

I use Kent's Tech M, and I know others do too.

Though with the salt I use I only have to add a cup full ever 3-4 weeks. (( I am using TM Pro, which has higher levels of Mag, I do have a good amount of SPS too ))

I also use Brightwell Aquatics Magnesion to raise and maintain my mag level. I use the liquid version. Tried the granular and it's a pain to mix up.

Tech M by Kent used here

i use a calcium reactor with koralith and magnesium media from brightwell, i use a ratio of 10:1 koralith:mag media, and it has keeped my mag at 1470 ppm for about a month now, this hobby is getting easier by the minute, lol

BTW if you want to raise your magnesium then use epsom salt, it works and its CHEAP. like 1 dolar for a quart, it should last you a long time, once you get it at a value you like then you can maintain it with kent-m, brightwell, 2 part or should i say 3 part, or just like me with a reactor

I use epsom salt. It's so much cheaper. Once a mo. with approx 5 gal. fresh water and 1/4 cup of epsoms. Mine stays around 1450

tropic marin bio -magnesium here and also bio-calcium.

 

[jamierk]

How much epsom salt is required to raise Mg from 1170 to 1300 in a 450L tank? Is there a problem in using this much sulfate and can this be done in a single dose or should it be spread out?

Thanks

Jamie

 

[sanababit]

use this to figure your dose and it should be done spread out thru out the day or days, i believe no more than 100 ppm per day
