I don't know if you are aware of this calculator, but this will tell you how much to add of whatever it is you use to bring up your magnesium level.

Yup, I've seen several calculators. I just don't like massive changes in any tank parameter in a hurry.

Also, I'm trying to find a 'recipie' that works for my setup so that I can dose specific amounts of Ca Mg Alk with my water change each week. If I can find the 'magic' numbers then I should be able to maintain fairly stable levels with my weekly water changes and not have to do any other dosing.

Thats the idea at least.

Use that calculator and dose to get to the proper MG... If you need to spread the major dose over 2 -3 days, then do so....

Once you are at the proper level, then as you stated, spend time trying to find out that daily recipe. And if you need to do a bigger dose again, then do so... Eventually you will get what the daily amounts will be

turn off UV if you are using pellets. UV will take away the effectiveness of the pellets
