I would like to know how other Reefers perform Husbandry on there tanks. 1. - What do you do? (eg do you vacuum your substrate) 2. - How often do you do it? 3. - Waterchange routines We talk alot about chemical additives, and checking water parameters, and how to make salt water etc. but we dont really mention how we do these things. I believe this could be a very valuble thread for new Reefers, and even old Reefers.
