Raising mg

Not sure if this has been other people's experience, but I did find that when I started dosing Mg, it did take a fair bit to bring it up. But once it was up where I wanted it, it was pretty easy to keep it there.
Once you get your levels where you want them, don't dose for 24 hrs, test again and use that as your start for maintenance dosing.

I try to target a max of 20ppm per day of increase when I have to do it. However, I just like keeping things a little steady in my system...lol

Quite surprised how much it took to raise. About half of a 1.2kg tub. Lol

I'm at 1360 now and will test around 4 pm to see what loss is in 24 hours.
No sure it its related to low mg but my terria del fugo lost some tissue. Should be ok as I still have PE

I always notice that the color on my red monti kind of gets blah looking when my Mg drops...that's a sign for me to check it..lol

I seem to be using 40 ppm mg a day. While alk is 1 dkh and cal about 30-50 ppm a day

Is there a ratio

when you dose, don't forget that the total water volume is different than the 'for every 70 gallon' rule. You must consider water displacement! If you were to take all your rocks out, then add the water volume of your sump as well, you might get a different number. I'm sure you know that, but - a lot of people forget that part!

What are you using to test mg?

[Proteus]

I'm using Red Sea. Seems good to me.

I'm use seachem a calculator. So punch I'm my numbers and what is desired and tell me how much to add. I base the calculator on 42 gallons which is what the volume is +\-

There will be, but it will be specific to your tank.

My tank goes through more Mg then dKH and Ca in a given 24 hour period, I attribute most of this to my clams.

And like was previously mentioned I too find that the brightness of reds and pinks in my system are also impacted by low Mg levels.

Well the clams may explain it. I had 5 sold two and have three left.
