So I ran my 1st water test and 2 things jumped out at me. I have a few leaks here and there and that my pump in my res pulls so much faster than my other pump refills it. I have a 1200 on the out and a 350 connected to a chiller. Maybe its bc the totes werent completely filled or I need a bigger return pump?? I'm running 2" between totes to a 1/2" return to chiller. If I chose to use a silicone or epoxy to seal leaks which should I choose??
