After a LONG week of waiting for my XP3 i finally received it this morning and set it up. My first impression of it when i opened the box was "wow, this looks really easy!!" Mind you this is my first canister. So i flipped through the instructions quickly and started to work. I loaded up the canister with the 4 sponges, some ceramic noodles, and the floss that goes on top. I hooked up all the lines, primed it and turned it on. It really is quite simple to hook up and probably only took me 20 mins total to get it out of the box and up and running. I had to really get down close to it to make sure it was on...its pretty quiet! So i cranked up the flow rate to full tilt and got that annoying whistling sound some people complain about the spray bar so i made the holes slightly bigger and its now silent. So i finished my setup and continued with my day. I come home about 4 hours later and am just totally blown away at how clear my water is. I changed out my substrate previously so my water had been kinda cloudy but now its just incredably clean! I took it apart after it had been running all day just to get an idea of what im in for when it comes time to clean it...super simple!! Just disconect the hoses with the simple flip of a lever, 4 locking levers to remove the top and pull the cages out...couldnt be simpler!! Im sold on canisters from now on...if it continues to deliver the performance ive seen since thins morning i will buy one for every tank i own!! Awesome filter and i HIGHLY recommend it to anyone looking for a good canister.
