So today's test results were somewhat what I expected.
The only one I found funny was my magnesium reading. It dropped 100 ppm in the last 4 days. During that time I only added 2 teaspoons of baking soda to raise my kH. Is that normal? Perhaps my corals were just dying for some magnesium. Im going to dose a couple things today now that I kind of understand how all of this works together. I'll try to get my parameters close to in check. Then what Im going to do is leave it for a little while, maybe 3-7 days to see how the levels drop. Then I'll retop them to where I want them. Do a water change, and see how a water change effects my levels. Then I'll know how my tank is changing levels no matter what Im doing to it and then I can work on just keeping them stable by dosing my auto top off reservoir for how much I lose during day to day changes and then I can dose my fresh batches of SW everytime I change my water too.

Ok so I've added today:
5 Teaspoons of Reef Advantage Calcium 8 Capfuls of Magnesium 3 Teaspoons of Baking Soda Im hoping this will raise my levels to: Calcium - >420 <440 ppm Magnesium - 1300 ppm kH - <130 pH - 8.3 We'll see how I do. I'll test again tomorrow.

So after adding that dosage, my tank water is a little bit "milky".
Was that too big of a dose for a 200G system? I dosed 10 capfuls and 10 teaspoons of magnesium or calcium in its own dose. This is hardly bigger than those, but just 3 elements at once. Good idea, bad idea? Im sure it'll clear but I just wasnt expecting that.

What do you mean, I cant dose all three of mg ca and baking soda at once? If thats the case then this particular dosing, I did not do that as I put all 3 into a 1G pail of RODI, mixed it and dumped it in the tank.

When I was dosing manually I always tried to leave at least a half hour between ca and alk doses. I don't dose magnesium every day but when I do I add it in the morning then my ca and alk at night. I also find it easier to premix a gallon worth of each solution so you don't have to bother with mixing each time. Check this link out for how to make homemade 2 part. I you let your calcium mix in before you dose your baking soda that should help with your milky water problem.

So after my latest dose here are my results:
Mg: 1200 PPM Ca: Between 400-420 kH:100 PPM (5.6dkH So Im gonna dose some more I guess. Still a bit low from where I wanna be which is: Mg: 1350 Ca: 415-435 kH: 9-10 dkH
