even on my tank I do a 10-15% water change weekly. I also test water weekly, clean skimmer, glass, overflow box, and salt creep
also dont be so discouraged if you start to see that your corals color dont pop like the photos you see... most of them lights are higher end lights and even then some are just photoshopped my favorite light for a cube tank is this light I posted below. A reef shop in Rochester has this light over a cube tank and wow the colors are amazing. They have a scoly and a bunch of high end zoas in the tank... looks like something from a movie
