Hello all,Im setting up a 75 tank that will feed a 45 gallon sump and a 20 gallon frag tank. I plan on having a medium to medium-heavy bioload. Im torrn between the Aquamaxxx em200 or 300 and the reef octopus NWB 150 or 200. I have a small (2") blue tang which is the reason im upgrading tank sizes.Total water volume will be around 110 gallons. Is the Aquamaxx worth the price over the much cheaper RO?
