Actually this is a refreshing topic as I can honestly say that I have reached a balance in both tank maintenance (healthy fish with very little maintenance) and also number and sizes of tanks (244, 210, 160, 145, 125, 100, 2-80's, 2-60's). As far as inside my home I feel I have reached a great balance and almost satisfied with the number and types of fish. Also having achieved a complete nitrification and de-nitrification cycle in all my tanks, water changes are far and few between and mostly tied to TDS accumulation due to dehydration.
