This is purely out of curiosity and pond inexperience. How many of you do regular water changes? I ask because I’ve been sorta blessed by the tank gods. I’ve had some doozies too but for the most part once my tanks are up and breathing, there is very little maintenance. I don’t fight with my tanks. Ponds? Clueless. Someone here told me to watch my pond just like my tanks and I’ll be fine. I watch my tanks closely. Ask my wife. She said I should get a lab coat instead of a bathrobe.
