I have a 58 gallon with 20L sump, I am using a mag 9.5 with a ball valve and manifold to power a bulk reef supply GFO reactor and a TLF 150 with carbon. Where is the best place for me to have the output before the refugium (middle part of sump) or directly back to the return area? If I put the output before the refugium I get added flow into the fuge, not much maybe just an extra 100 to 150 gph.
