help with dosing MAG

Is 11 acceptable for alk? I have seen many people keep their alk high at 11 but test kits say between 7-8

 

depends, are we talking dKh or meq/L?

 

11 in dkh

 

thats usually where mine is. i believe the recommended for marine reef is 9-10.

 

So you have no problems in your system
With it at 11?

 

7-11 dKH is the typical acceptable range.

Since this is starting to diverge beyond just Mg, you might find this read worth your time; an oldy but a goody: Reef Aquarium Water Parameters by Randy Holmes-Farley - Reefkeeping.com

 

nope. some people claim to keep it at 15, believe it or not, but no one should be recommending that. if its 10-11 and stable you should be ok. like most things, stability is key. large swings of anything are worse than moderately high/low levels held constant.

 

Ok what about if my alk raised to 12 today and mg is at 1200. Should I keep dosing? I don't know where the mg I'm dosing is going.

 

Update. Mg 1240 ca 460 dkh 10.9

I can see this is a very slow process lol

 

Ca and Alk look good there; I wouldn't do much more with them.

FWIW, it took me a while to get my Mg up when my tank was new as well. I always attributed it to it getting absorbed by the rock until it eventually got saturated equal with the water.
