I recommend a really good skimmer and nothing else. The skimmer will remove "floaties" just fine. A general rule for rock is 1 -1.5 pounds per gallon, but that isn't set in stone.
The wet/dry will create more nitrates than your rock will be able to remove, so really, save your money. Sell the cannisters and put the money towards the skimmer. I'm not sure if Titus is still making the Canreef skimmers, but they have had good reviews from the people that have commented on them. There are many others to choose from, inclusing Euroreef, PM bullet, aerofoamer, etc. The price for a good skimmer can run you between $400 and $1000, depending on your tank size and how aggresive you want to skim.
Also, DIY skimmers are always an economical way of getting a big skimmer at a small price. Used ones come up for sale often, or someone might be able to build one for you.
People have differing opinions on skimmers, but my thoughts are buy the biggest bestest skimmer you can, otherwise you need to buy a second one down the road to replace the crappy one you thought you'd save money on.
And even though this is one of the most confusing parts of entering the reef hobby, just keep asking questions and you'll figure it out just fine.
