I set up my 29 gallon Bio cube 21 days ago. I didn't do the research first I know bad Shawn(that's my real name). Question is I have been topping off my tank daily about 1 gallon maybe a little less. I think because I using a desk top fan to cool the water. Anyways I have added 20 gallons of RO through top off. In your option have I removed most of the tap water?
