anything bad about over dosing Mg?

[SeaFish]

is there any thing bad about over dosing Mg? how does it affect fish and corals?

theres nothing wrong. its actually good to dose Mg, helps you Ca stay Ca, instead of precipating out.

thanks for quick reply, but would it be detrimental if overdosed?

like anything else, too much of something turns it into poison. "at what level does mg turn lethal for your livestock?" is something i don't know and wouldn't want to test out.

 

i would guess you could approach 1400~1600 ppm based on it's relationship with calcium but that's really an advanced question for rhf (reefs.org's resident chemist) or someone similar to answer.

 

i usually just dose according to the mfg rec's and adjust by freehand depending on how each individual system looks (specifically gauging coralline spotting/growth). hth

here's some info on magnesium: http://www.animalnetwork.com/fish/library/...a&RecordNo=2856

 

it's an article by Randy-Holmes Farley, who mods a forum over on reefcentral.com. might want to ask him any questions after doing a search over there!

thanks u guys for the quick reply. i am asking because when ever i add alk to my tank, my Mg decreases and my alk dont seem to be maintain high if i add Mg. my calcium is around 450 most of the time.

 

i recently posted a new thread about this problem, i was wondering if this is normal or if i am doing something wrong.
