Alkalinity

OK really quick question is 3.15 low for alkalinity idk what there were mesering in i think dkh and if it is high or low how do i raise it thanks.

 

bump

 

hey I use the api test and shoot for 9 to 11 drops which equals 9 to 11 something I forgot but that is what method I use

 

3.15 sounds like it's probably in meq/l (milliequivalents per liter), you can do conversions here.

9-11 is probably dkh which is another common measurement.

3.15 meq/l is a fine level, but if it's dkh that's extremely low and I would be surprised if it really was that low.

Here's a good article on chemistry basics which includes information about how to supplement. Feel free to skip over the technical stuff there's still a lot of good information here.

it sounds a little low but thanks

 

9dkh or 3.15 meq/l is definitely not low. It's where a large number of people maintain their levels. Some people like it higher but there's no problem with keeping it in that range.
