Fish net indeed, a nice big 12" handle and 6inch net for me, However I usually turn my filter back on before I have topped up my tank with fresh water when doing a filter change, it makes it so much easier to catch the dirt that pops out than if it was a net submerged.
When I do proper filter maintenance I take everything out of the filter, the impeller give it a good cleaning (be very careful with the Fluval 05 series impellers as they are on a delicate ceramic shaft). I give the media a good washing in the tank water I have just removed and then I take the filter casing over to the sink and was that out with pretty hot water. It seems to fill up with gunk a lot in the 05 series for me.
You don't need to prime again once you have the Aqualock system holding a siphon on cue for you. After the water change I normally place all the clean media + filter back together and place the aqualock on then just open the valve, the siphon should still be there so it will quickly fill up, at this point it might be a good idea to start holding your net over the outlet nozzle. Sometimes when the siphon works it comes up the outlet hose with enough force to launch a bit of poop out. Once you hear that the filter has filled up and the outlet hose is filled I normally just turn it out, take advantage of the decrease in water level due to water going into the filter for some room to play with the net. Turn the filter on at the plug with your foot and lean precariously over the tank awaiting the possible impending torrent of poop.
A good line of filters, just I don't like the ribbed hosing for that although they do feel a lot more sturdy and easier to manage.
Edit: No need to use the primer once the aqualock is holding the siphon for you. Also I only fill the filter canister up with tank water by opening the aqualock not pouring water directly into it. The Fluval 05 series also seems to be a good bubble catcher internally but it may take a few minutes afterwards and all the bubbles will be pushed out so don't worry. I don't think frantically pumping away on the tiny primer is going to help that much. Just turn it on at the plug once the canister has filled up to the outlet after opening the aquaflow valve.
Edit 2: BTW just reading back there about cleaning the hoses if you were to take them out, if you don't have a garden hose like myself you can either ram it under a tap and full blast it out you can just put a little water into the hose and cover both ends with your thumb, then raise one end up and the other end down as fast as possible just as if you were milking a cow... a giant cow that is. That will dislodge a lot of crap left in the pipes then just take your thumb of and run the water out, do it a few times and they'll be golden. It's not really necessary though when you just use a net to catch the crap.
, although i could rinse it in the tub i suppose.
