It's funny all the arguments about filtration haha, so I'm going to throw in my two cents lol.
Personaly I say the only thing filtration wise that is required for a reef is a algea scrubber. Though thats assuming the scrubber is set up correctly and maintained correctly (which isn't that hard).
Skimmers do remove things from the water that benifit your corals, its a fact, but at the same time the remove things that are bad, and yes you can reef very successfuly with a skimmer, but using one is unnessisary and expencive in my opinion (especialy when you get into big tanks).
The good thing about scrubbers is that the dont remove good things from the water (unless you have decorative macro algeas in your tank), they only remove the bad, like nitrates, and phosphates they also help with nitrites. Best of all they also remove the need to water change to get rid of nitrates/phosphates (which is the primary reason for waterchanges), but if you dont have a calc reactor you have to suppliment the calcium/mag/stront/etc or your corals wont do well. So scrubbers mean less salt to buy, and less RODI water to make as only evap water needs replacing.
Scrubbers also harbour pods, the pods live in/off the scrubbers algea, then free float into your system where fish like dragonets and seahorses, as well as your corals (to name a few things that like pods) can consume them, which makes keeping picky fish like dragonets and horses easier.
SO in conclution of my lengthy post lol a good scrubber is better then a skimmer, canister, wet dry or any combined, but thats assuming proper bio filtration is going on as we all know without proper bio the tank will die haha. But at the same time I'm not saying what your doing is wrong, if it works for you go with it, I'm just listing an alternative for your and others concideration.
