Alkalinity Conversion

I have a question for the panel on reading my alkalinity test (Seachem)

I was told or read that a good alkalinity was 8 - 8.3 dKH, so thats what I'm striving for. Seachem test kit for alkalinity reads it in meg/L. The latest test I ran I got a 2.5 meg/L reading.

2.5 meg/L = ..... dKH? Any ideas?

7 DKH

meq/L X 2.8 = DKH

For a balanced system with that alk, your CA should be in the neighborhood of 410

Hi

dKH=meg/L * 2.8

Some kits use mg/L in which case there is a factor of 50. So first divide by 50 then You have meg/L then multiply by 2.8.

In your case just use the first formula.

Send a message via ICQ to jackdp
7 dkh is a little low, you should shoot for 9-11 dkh. With a calcium of 400-450ppm.

If your CA is around 410 it's fine. Balance is the key, CA and ALK have a relationship.
