i have a 72 g bowfront with a 45 g sump w/refugium my skimmer chamber is set up for dual inputs(has 2 socks) and the refugium has 1 as well . rather than trying to split drain lines to accomodate the three drains. i think i am better off to run all 3 standpipes into the skimmer section. then t off of return going to refugium. my return line also is split at an 1" scwd then goes to 3/4" mod tubing in tank .the pump i am planning to use is an iwaki md40rt i cant seem to find much info online to find out specs since it is an older pump. my question is does anyone know the gph (if i had to guess i would think around 750gph but not sure) is this pump large enough for this system? if not im open to suggestions also ill have 2 tunze pumps for a lot of flow in display tank so i dont think i need a crazy amount but dont know what the t coming off the return line will eat up in pressure..:fun2:
