so dont use a filter at all?
i use a fluval 4+ in my tank. i do weekly WC's. as far as im aware, internal filters dont do too much in SW aquariums (not much info on using then in SW), so they basically act like a powerhead, just movng water around the LR.
you can just run a tank with LR and powerheads, but with a skimmer your overall filtration will be so much better. sumps filled with LR are probably the best filtration a SW tank can have. im adding a sump/refugium to my tank. gonna give it a deep sand bed and some mangroves to cut down on waste products in the aquarium. and some LR rubble too. i hope to remove the filter then as it takes up a bit of space. or replace it with a smaller one. but im still researching that.
the only reason i dont run a skimmer is because i cant afford to get one. i decided that my tank would benefit more from the sump/refugium than with a skimmer, so the sump gets built first. if i come into money i would probably get a skimmer, but only after i got better lights.
skimmers do work, but i think they dont have the same value £ for £ as other forms of filtration.
i.e. im building my sump for around £40 including the sand, rock, mangroves ect. id be lucky to find a decent skimmer for £40 even used. that is unless you make it yourself...
