Raising Mg
 

I've been trying to raise my mg for a week and a half now. I have been using the Elos tests and dosing the max amount of mg per day (10mg / 20 gallons) for over a week and I'm still only at 1000 mg. Is this normal or should I be concerened with either the test or something else?

What is your Calcium at?

Calcium is at 360, and I have been using brightwell aquatics magnisium. 100ml per day for a 220 gallon tank.

You might want to try bumping them in tandem, although dosing on alternating days. However, if you are happy with your Ca. level, I'm not sure what to recommend to you. I usually bump/maintain my Mg. levels with a Mag. additive in my Ca. reactor, or I used to dose mag cystals from Little Silver Max. I have never used a Brightwell product, so I don't have any hands on experience with their stuff.

Thanks Ill try the mag cystals from Little Silver Max. hopefully that will help.

Thanks for the advise,

Rene

By using one of these reef calculators you will get a better idea of the dosage necessary to bring your levels up to your desired level.

I've been using Mag from LSM for about a year and it works great. I figured out how much my Mag, Cal, and Alk go down per day and dose accordingly. In my case I had to overdose quite a bit to get levels up. Now maintaining with daily dosing is easy.

Is it odd for it to be so low? I had been using instant ocean salt, but have recently switched to reef crystals. The tank is only 6 months old.

i tried everything to get my levels up at one time.. I find liquid additives dont work well.. Then I tried the reefchem mag flakes.. wow.. brought it up very well over a couple days.. I use this now in my new IO salt for water changes..

Liquid additives are diluted. Dry chemicals - especially anhydrous ones - are nothing but the good stuff. jdieck's calculator that TomR mentioned is very useful also in comparing across brands/methods/mixtures of how much you need to bring your levels up.
