Hubby watches me do it, every day. He's responsible. When it's his turn? He looks at fish food like it's poison. He learned to acclimate, once, when a delivery was delayed by weather, but he wouldn't know what to do with testing or dosing. This morning he asked, not for the first time, what those white pellets were and why were they swirling around that tube thing....Easy. I hire a responsible individual to do testing, dosing, feeding and to give me all my updates
