I've got four plants in an 18 gallon Sterilite. My mom-in-law gave me three 30 gallon tubs today she couldn't use. I never put fresh tap water in my grow rez. I always let it sit in a separate 18 gallon for at least 48 hours before I use it. After 48 hours I pop in a bubbler to keep it aerated.
The full idea is run a supply line to my prep rez with a tank float and then put a float in my grow rez that triggers a pump from the prep rez. No more bucket filling.
