Hey everyone this is my first post. I started my 50 gallon IM lagoon at the end of November. I started testing my alk, calcium, and magnesium on December 23. My alk started about 11.9dkh, my calcium started at around 290ppm, and my magnesium was at 1100ppm. I figured I’d do water changes and see my calcium and magnesium come up and my alk come down. I test weekly and my alk has dropped to 10.7dkh. My calcium rose to 325ppm but then dropped to 320ppm, and my magnesium rose to 1150ppm but then fell down to 1050ppm. I’m mixing my salt to 1.025 using Fritz RPM. Btw I started the tank using water from a LFS. Is this something that I should just keep doing water changes and it’ll eventually level out or do I need to dose? I change 5 gallons of water out each week which comes out to a little over 10%.
