Hi, If any of you are like me and can't remember wether you dosed macros or Trace mix the day before early in the morning when I hasten to guess most of us dose then this may be of some interest. What I have now started doing is my water changes either lateish Sunday evening or early Monday morning (before I go to work). Now Monday starts with an M as does Macros and Tuesday and Thursday with a T as does Trace. Now all I need to know is what day of the week I'm on, mind you I can still easily get that wrong at 5am some mornings, LOL. The other bonus is that Sundays is usually the day that I would do any tank maintenance , especially the tank gardening which may involve disturbing the substrate and so it fits in nicely. Saturday abd Sunday mornings are reserved for staying in bed late,(often beer fuelled) so therfore no dosing. How/When do you do yours? any tips and tricks for remembering what/where/when? Regards, Chris.
