Canister filter leaking like no tommorow

I have never had a canister filter leak in 20+ yrs and at times running over 30 of them at the same time.

Bob, when did canisters start to become affordable and available for the smaller household tank? When I dabbled in tankery in the 1970's and 80's, it was something to have a HOB and fluorescent hood! As far as I knew, only LFS's had things that resembled canister filters. Pretty much everything household was box bubbler filters.

My first HOB was a DynaFlow(sp?). Had an actual fan cooled electric motor that slid onto the bottom of the plastic water tank of the filter. Worked great IIRC.
 
I've had my C-360 leak after I didn't change the O-rings on the valve block soon enough. I'v also had to tear down the entire top unit to fix the pump. It had gotten some grime into it that prevented it from working right and caused it to leak. These where of course small slow leaks that didn't cause any issues.

Mine was more of a sudden pouring out of water, definitely thinking it was from me messing something up when putting it back together after cleaning. Off topic, but what do you use for media in yours, Im out of everything right now and am considering DIYing the filter for more mechanical and chemical filtration (already have two honking sponge filters for biological )
 
All of my canisters are set up the same way; mechanical on top mechanical/ biological in the middle, and biological on bottom.

Unless your canister filter draws unfiltered water to the bottom first. That case you'd need mechanical media towards the bottom for proper operation.
 
The sponges on the bottom, #2 full of loose carbon, #3 those plastic round biologicals, #4 ceramic rings with the fine filter pads on the top (cut to fit).

I only clean out my filters twice per year as its a fully planted tank with moderate stocking. This setup keeps it crystal clean. T
 
in the house and under the stand I keep my canister in a large rubbermaid tub.

it worked great when the mag 350 started a leak at the hose connector(quick disconnect) bad o ring...all the water that leaked out, leaked into the tub and none got on the floor. ;)
 
One thing every owner of a canister needs to remember: always keep an eye on it the next couple minutes after plugging it in!

Have to find the right size rubbermaid for my stand first, but right now I have it in a bucket. Wont stop a serious leak but if/when I screw it up again I'll be covered for long enough to shut it down and fix it.

Yeah this is pretty much the same setup I have going, might switch out some of the bio stuff now that I will have two honking sponger filters in there too.
