175 gal. Sump, external skimmer, sulfur Denitrator, co2 scrubber,
Current stats:
temp -----77.8
PH -------8.2
CA -------540
Alk--------7
SG --------1.024
MG--------1470
No3--------20
My tank has been in sad shape, lack of color, coral frog spawn has decreased from a tank full to very sparce through out. I added the sulfur denitrator to lower No3 that works nicely. Then I added the co2 scrubber to balance Ph. I did all the new equipment after the decline of my tank.
As you can see my alk is low at 7.
Last wk it was 7 and the week before that the same.
The reef chemistry calculator says to add 8 oz Alk. I have done this for 4 wks in a row. Then the next wk it is back to 7.
Ideas please
