Tell me about magnesium!

[StirCrazy]

I think Mg was depleted by DSBs. I needed to add it from day 1 when I had my DSB. when I got rid of my sand I only needed it to bring my water changes up to normal levels, which didn't take much with my IO. I was testing between 11 and 1200 in the IO so I would bring it up to 1350.

now I also found that when I hooked up my ca reactor with ARM media I didn't need as much also.

what I also found is that some people could use it with out even knowing. if you are pounding a Ca reactor to your tank and adding kalk through make up you could be masking the Mg condition. I could maintain my Ca that way with my old tank but I found that when I brought up the Mg I had to dial back my Ca reactor or my Ca would get to high.

I blame it on DSBs

Well, ya, but today's LED systems should counter that, no?? -lol

Since my reactor days, I have added magnesium, { following Ben,s formula}, to my IO salt mix. Thats kept mine over 1350ppm, usually just over 1400ppm. I,m currently trying some Seachem salt, that has higher mag levels.

When I ran my co2 reactor, found the same results as Tony using Carib Sea ARM. Levels always stayed up, so it must give a decent amount of magnesium also.

well, less heat = less evaporation + reduced need for fans. so ya salt creep should be reduces and make up is reduced so it might
