I take care of two tanks for my elderly parents. My dad needs slot of help to remember to do things. Right now I put the Easy Green and Easy Carbon in pre-metered vials (one vial for each per day) in a tray labeled for each day. This works well for the large tank but not for the nano tank. The vials are so big he can never tell if he used them or not with the small amount of liquid in them. Can I pre-mix the easy green and easy carbon in a large vial of water? I am looking at like 1ml of each with 10ml of water. This will make sure he keeps up with the doses.
