Hello once again.

Some of you may already know of what I am about to write about but reminders are not always a negative thing.

I am to the point in my system that I need to start dosing the three main ingredients. Calcium, Alkalinity and Magnesium.

Went to my LFS and they gave me the Calcium and Alkalinity suggestions. All good.

Now my Magnesium was on the lower end, 1180. I began the Calcium supplement and raised my calcium from 400 to 430 in one week. I continued the calcium supplementation at the same rate and calcium held steady at 430 so I know for now to keep adding same amount.

In the second week I began supplementing the Alkalinity. In the beginning it was 7.28 dKH but with calcium addition went to 7.35.

Well adding Alkalinity solution in second week raised my Alk to 8.5. That is OK BUT my Magnesium levels rose to 1390 in that week. Now I am using Seachem's Reef Builder and found out it has ample amounts of magnesium and strontium as well.

Well the moral of this story is that had I not been properly testing and keeping records I may not have noticed this. I could have continued using the Alk supplement to get to my target of 9.0 and sent my magnesium through the roof with continued use.

As we know Alkalinity drops a lot faster than Magnesium.

I will now be making my own Alk supplement using baking soda and make my own magnesium supplement.

Now will have to research strontium.

Love this hobby.

Just an FYI from my journeys.

Nice write up.

As for your comment about alk dropping faster than mag is not entirely true. All tanks are different with their demands and how fast they get depleted.

My advice is never dose anything without testing first and keeping records to monitor ongoing levels.

Point taken Tmah and thanks. Most articles I have read seem to indicate Magnesium depletes more slowly than the other two BUT as MrSaltwaterTank says: "Know your tank personality."

Interesting Tmah.

Can I ask what in your system setup makes this happen when most systems seem to use magnesium at a lesser extent than the other two?

Is it the type of corals or what your filtration system consists of?

Being I run Biopellets this would be something to keep an eye on as carbon dosing of this type may effect my levels differently.

Hmmm. Interesting.

When adding supplements you should add Calcium and Alk at the same time and when using baking soda it should be Baked Baking Soda.

Not necessarily true. I have added calcium and not needed the alkalinity for a few days. Just need to make sure to test.

Thanks all the same.

Really? I wonder what the masses would say. It's all about keeping your perameters stable. but if you've got a better way then as they say you learn something new everyday
