Your choice for maintaining magnesium

[gbcichlids]

Looking for some input here. Bought some liquid crap called precision mag from a local lfs and it seemed to lower my my mag which is around 800 ppm now. Tested with two different brands so I believe the results pretty true. I also tested a fresh batch of new water for a water change and the reef crystals tested 1050 and 1100 from both test kits.
Calcium and alkalinity both were in normal range. I know the three ions work together in some configuration and would only like to adjust the mag. Bulk reef sells the mag chloride flakes and appear to be favored over most of the other options.
Bottom line all of this; what do you use and why!
Thanks,
Randy

I use the BRS mag since it came with the 2-part. Once I started using it I had no troubles maintaining my levels.

I too use the stuff from BRS. Cheap and works great. Before that I had used the Tech-M product. It too works, but it sure costs a lot more.

Dolomite in my Ca reactor maintains mine. Buffer it to where you need it and the dolomite will keep it there.

I use the BRS mix now but would like to go the calcium reactor additive route in the future.

Mag flake and epsom salt. Cause its cheap.

If using a ca rx then use something like zeomag (not dolomite!). Dolomite will add more alk thus throwing the alk, ca, and mag proportions out of wack.

Otherwise I'd use the BRS mix which is similar (or a replication) of Randy's mix.

That's exactly what I had in mind....:bigsmile:

Hope Rev doesn't mind the link to an RC thread but this is why dolomite isn't a good choice for mag supplementation in a ca rx.

I just don't have the time and energy to reiterate all the info and explain the chemistry. It's easier to just read it for yourself.
