Heh. None. No, I do a 40-50% water change every 4-6 months. Primarily to reset any imbalances in trace nutrients and try to reset nitrates back to reasonable levels, if only for a week.What's the water change schedule on that size of a tank ??
40-50% is 140-150 gallons, which is pretty much an entire bucket of Reef Crystals. I probably should do that monthly, but I'm trying to find ways to streamline my time and improve the habitat. It's somewhat working. No hair algae in the display (Huge win for me!).
However, the glass is covered within a day and it takes me 45 minutes to clean all 4 sides since no one makes a 6-8" wide scraper (would love that) It's built into the wall, so, Getting to the sides from the outside is not possible. The sides must be done from the front and rear of the tank. So, guess how many days a week my glass is clean? --- Hint: 1. . .
