Ive learned over time that the smaller the tank the more water changes are required. I have a 24g with water changes every month, a 55g changes every 3-4 months and a 125g every 6 months. No problems. Anything longer than that it starts effecting the oxygen levels
WOW....and here I was worrying if I skipped missed a w/c...I try every other week....
