Replace root tabs in a lush, established, dirted tank?
Is it necessary? I suspect it might be more stressful to shy occupants to have me digging around in the back of the jungle-like tank. Plants don't appear to be wanting for anything. I follow Seachem's schedule and dosing (eventually may switch to dry dosing to save money, but for now the liquid stuff is pretty idiot-proof and my plants look great).
