yes picked it up today ,I hope to have it installed soon , I have a panworld 200 return pump on my tank now, does that mean i can just run it in line with the pump ? I was told which Im ok with to just attach one or two of my return hoses from the tank to the chiller , then have the chiller dump into my sump, which then flows to my tank through my pump. I have all four of the drilled holes as returns and built a manifold coming strraight from my pump to my tank. One return should be approx 700 gallons with two at approx 1400. So my thoughts were to hook one return hose or pipe to the chiller then have the output from the chiller flow into the sump. ? It recommends that the chiller be last inline just before the return to the tank. thanks again for the help.
