Welcome to canreef
I say this to all who run with a canister filter. Take out all the sponge filters and media in it and fill it with liverock rubble. It's the best thing thing filtration you can use in a canister filter. When you do clean it just use water from your water change to rinse the rubble. You can also put a nylon sack full of carbon in one if the compartments to polish your water. As for peppermint shrimps, go to a reputable LFS as quite often stores sell camelback shrimps as peppermint. You can put a chunk of prawn in a piece of pantyhose to catch bristle worms if you would like to thin them out.
