I just did my weekly water testing today and found that over the last month and a bit that my alkalinity is dropping while my PH was staying steady at 8.2. I was under the impression that alkalinity and PH were tied together. Is there anything I should do to raise the alk? I'm using the red reef test kit and the scale shows me that I'm on the low side 2.0.
Parameters are:
SG 1.025
PH 8.2
Alk 2.0
Cal 420
Ammonia 0
Nitrite 0
Nitrate 0
The tank has been up and running since October of 2010 with mostly LPS corals, and 5 fish, CUC, etc. (120g)
Is this normal? Also I found that changing 20gal every two weeks seems to keep everything in check. I test right before and then 24-48 hrs after the pwc and all remains the same except as stated above for the alk in the last month & a bit. Thanks...
