How big are your colonies and what are you using for watering?

I currently have 3 27 gallon totes going and they are super over populated LoL
These totes <----

I am using these auto waterers from Walmart but they are a pain in the butt to clean.
Plus they take a ton of water crystals compaired to the other waterer that I have.
