Multi Tank Sump Systems

[zum14]

Just remember, the only problem with having a sump for all of your tanks is that if there is a sickness in one tank, all tanks will be pumped with the same water. The upside is more water volume for the entire system makes it more stable. Only one filter to clean for all tanks, water changes are from one area. Its a tough call. Ill be running 3 or 4 tanks on one "sump" but will also have a seperate system for quarantine or hospital.
