Hey man! Happy to report some minor success. I was able to get some fresh air to the tank which cause a series of events PH related. Temp 77.8 Salinity 33.5 PH 8.29 Alk 7.6 Cal 405 Mag 1210 P04 .01 N03 2ppm I have my comp 123 but haven’t needed to dose because my alk never moved. What Alk should I remain? I’m think 7.5. Then monitor it figure out how much it’s using. It’s gone from 8.6 to 7.5 in 3 days that a drop of .3 ml per day. Am I thinking through that correctly?
