My last couple tanks I went a couple years without changing water and moonshiners and all these other programs weren’t around or thought of.. I’ve had success with just vodka dosing and mb7 myself.. I topped off with off with kalk and dosed 2 part back then.. now I got a monster tank again today and water changes are a chore again sooooooo…. My routine is carbon dosing “bacto balance” and all for reef with zero water changes.. top off with kalk and everything is happy just like back in the old days.. Sps dominant then and now.
