I was laying in bed this morning thinking about doing a waterchange and thought about it and said to myself "the tank still looks fine". then I thoufht about it. our tanks should never look like it needs a waterchange because whatever is making it look bad is already there. seeping into rocks and affecting livestock. the motivation to do a waterchange (note to self) is to KEEP it looking and being good. so yes my weekly waterchange is now calling me so I will get up in five or so minutes and go prep my water for Todays waterchange.
