That's my kind of maintenance routine... Wish I could see the picture but do you have any coral in the tank, particularly the stony types that would need the cal/alk maintained? Are water changes needed less frequently with the macros assisting in nutrient export? What are your usual nitrate levels?
Hope you don't mind all the questions but I've got a 40 gal running that is going to be a BTA tank with maybe a few softies once it matures a little, still trying to work out my stocking and maintenance strategy.
