Daily Water Changes

[michika]

Most people actually change weekly, bi-weekly, or monthly. However if you want to go the daily route Red Sea will last for about a week provided you have it running with a pump to keep it mixed and a lid to prevent evaporation. You will probably want to test it before you use it though. The biggest I've ever mixed, and it was with Red Sea Coral Pro, was probably 55l (in a garbage can), and it ran for about a week or so.
