I am looking into RO/DI filters and am taking your guys's advice. Do you all think spectra pure is the way to go? and even tho I have a 72" tank from what I've read I wont be doing very big water changes? Sorry but I just sold my 30+ fish and am used to doing 50% or more weekly..... So if I am only doing small water changes lets say 20% a week(is that a good number?) which size would I need what are your suggestions?
THANKS
20% weekly changes will be more than adequate with a good skimmer, and good fish husbandry.
