Hi there, my name is Chris and I'm a legal caregiver in AZ. I have finally finished my purchasing and am about to begin my setup of my new DIY undercurrent system. I learn more by reading on here and filtering out the BS than anywhere else.. You sir are a block of knowledge that i need access to.. I will keep a journal and post pics as I go, can you give any advise now?? The system is a 12 site evolution copy but with 18 gallon totes, I am using 8" net pots on top of them, 3" uniseals, 3" Black drain pipe (same sizing as PVC), (2) 3/4 PVC return lines, (2) 951 GPH Return pumps - ONE FOR EACH LINE - (In case one goes out or gets clogged, I thought two exact pumps would be cool) ?? Should I use a tee or independent return lines after the pump since I am using 2 pumps for return? - 54 gallon epicenter controller bucker - 1 HP Chiller will 1" in/out - My email is therainbowgardencoop@gmail.com and my name is Chris
