I have a 200 or 210g tank and a 40 gallon refugium/ wetdry. What would you guys suggest the turnover rate be. I researched and a lot of people say 4x-6x with that style filter. So I was planning on getting this eheim pump rated 900gph with 6ft Max head for the sump. Will that pump be enough? I have two 1" bulkheads for drainage from display tank into sump.
