I'm building a custom DIY sump for my 180 freshwater tropical tank. Ill be using a 40 gallon breeder. I have most of the build figured out, I just need some advice on mechanical filtration, I would like to get my water as clear as I can, down to 50 microns or less if possible, I'm starting with a 300 micron filter sock then I want to step down to 200 micron then 100 then 50. I know that a 50 micron pad would clog almost immediately but what if I stepped down to that size? Could I still keep my cleanings to once a week? Or Could I accomplish my goal with filter floss? Just the cheap polyester quilt batting? I just want something that's going to pollish my water to god like levels of clarity that I don't have to clean everyday! Is that too much to ask? Also I'm shooting for 6X turn over, should I go for more or less when using a sump on freshwater?
