Personally I just plan on running it when I do cleanings / simulated storms.
First of all, please explain "simulated storms", their purpose, and benefits to aquaria.
Next, I have a Magnum 350...the regular version. I ran it on my tank only until I had enough LR for filtration. Now I hook it up twice a month to run carbon in. Both the deluxe and standard versions have the carbon chamber. i have been thinking of selling it, because I use it so infrequently.
A lot of people will claim that canister filters are nitrate traps unless weekly maintenance is done. The maintenance includes changing media, clearing dirt/debris, and cleaning the intake/output hoses. The deluxe version is better for maintenance because it does have the valves, but you can buy these valves seperately at any hardware store. It's also not too hard to clean the canister without the valves. You just unplug it, remove the sump from the motor, and drain the lines back in to the tank. Just make sure that you open the canister outside, or someplace that can be wet.

I have never used a turkey baster to clean my LR. I do use one, though, to spot feed corals and such. I have heard of people using one to remove detritus and dust from rocks, but that's when they set their tank up.
