This is a very easy to use Canister Filter. This is my first Canister Filter though so I don't have any experience with them, but Marineland provides a very easy to use DVD to help set-up and maintain your filter. My only complaint is that they only provide 3 suction cups for the filter. This is great filter and I would definately recommend this to anyone.
I'm setting up a sumpless reef tank and decided to go with the Marineland C220 as my mechanical filter. Right out of the box I was impressed. The dvd is a "must watch" as it answered all my questions. No problem with priming, just be sure you fill the canister prior to start up. I highly recommend this filter.
This is an excellent filter for any aquarium owner. What makes this purchase even better is the super fast shipping and great packaging for this product. It came in perfect condition and everything I needed to get started filtering my fish aquarium.
