Howdy, just purchased one of the new Waterbox Marine tanks (90.3) which has a 60g display and 28g sump. I currently plan on getting the RO Varios 2 for it, was wondering if anyone had any comment on that? I'm not a math wizard harry but seems to come out around 7-8x with headpressure. If I'm wrong or there's something I should know, that'd be great. Thanks champs.
