thinking about converting a 30 gal tank into refugium for my 55 gal DT. will have to use overflow as I can't drill tank. question is at what flow rate should I aI'm for , I will be putting my skimmer in refugium which is rated at about 350 GPH . I assume I should maybe aI'm for 300 GPH in and out of refugium ?
