Are you testing nitrate and Po4?
Yes once a month I test nitrate, phosphate (all undetectable) and calcium. I weekly test salinity and alk. I do weekly water changes of one gallon - 10%. Salinity has been very stable at 1.025, alk still varies around 8.0. Still working on dialing two part in.
Separately i wasn't getting much coralline algae until I read a report that said you won't of your white spectrum is too intense which mine was. I don't really like scraping coralline algae of the glass and pumps but it is a good indicator of stable tank so each week i lowered just the white spectrum on the lights and now I've got coralline algae growing all over the tank. I've also noticed that zooamthinds looks better too. So far SPS appear unchanged.
