How soon should I change the water after I dose my tank? How much should I change out also? This is my first time dosing to get rid of planaria and I'm a bit worried of losing baby shrimp and berried ones.
Your shrinp will be fine, even if you never do a water change. Panacur is short-lived in your tank, you can do a water change after 48 hours, but that's mainly to remove ammonia caused by the dead planaria. You may have to dose again in a week to make sure you got them all.
