I agree. In principle, the design of a canister filter does 3 things very well. 1) They break down ammonia and nitrite, resulting in Nitrate. 2) They trap particulate matter, resulting in the breakdown of organic molecules, depleting carbonates and increase nitrates. 3) They allow for a place to utilize chemical media, such as activated carbon or phos guard.
In the marine aquarium, principle #1 and #2 above are degrading to the environment. The only concept we utilize is #3, and even then in very specific situations which do not apply to newly set up aquariums.
You and I have the same size aquarium, a 180 gallon tank. My tank, pictured below, and almost every other marine aquarium you will find on this forum in the Pictures & Videos area http://www.tropicalfishkeeping.com/s...ctures-videos/
, all utilize the same filtration principles. These are live rock, aragonite sand, and protein skimming. These are the principles that lead to success in the marine aquarium.
You may already be using this technique and simply use the canister as an auxiliary carbon filter. If so, wonderful! We'd love to see some pictures of your setup.
Here is a link to my 180 FOWLR, using a protein skimmer, live rock, and aragonite sand as the only filtration system:

. Hopefully this gives you some help.
On the subject of salt, at this point just continue to utilize water flow to fully dissolve the salt. It may take 48 hours or more.
