How to clean my magnum 350 filter

1/ turn it off
2 / close both sides of the disconnect valves
3/ split the valves apart by turning counter-clockwise
4/ now you can remove the canister from the motor base/ pick straight up on it
5/ open both valves on top of the canister/ turn it upside down over the kitchen sink,,this will empty all the water from it
6/ unsnap the 4 metal clips around the top,,, remove the top,,,, all the yuk and spooge is right there
7/ lift out the basket,,,, pull the blue filter element off and discard it,,,you can cut it off with a scissors carefully so you dont have to touch the spooge too much
8/ dont worry about touching the spooge,,, it's just a lot of fish crap,,,,, it washes off
9/ remove the basket cover/top,,,empty out the charcoal
10/ rinse off the basket and top with tap water
11/ fill the basket with new charcoal,,,, rinse with tap water to remove black dust
12/ be careful with the gaskets and 'O' rings,,,, they have to go back in the exact same position as it came apart
13/ rinse off the internals of the canister with tap water
14/ be careful that the impeller at the bottom/ inside goes back into place ( it's the yellow twirlie thingee),,,
15/ then the internals go back in original position,,, it only fits one way
16/ the basket goes back in/ the flat side toward the internal black pipe
17/ the internal black pipe goes into the hole in the canister top/ rubber gasket on top of the black pipe
18/ then the top goes on,,,there i a knob on the top and a rounded slot on the bottom,, they must match up and the black pipe goes into place
19/ snap the metal clips around the top,,, oh, there is a big rubber 'O' ring that goes between the top and can
20/ now you prime the pump,,,, using aquarium water,,, pour or use a small hose to put water into the,,, OUT,,, valve,,,, both valves open,,, water fills from the bottom and the other valve open allows air to escape,,, when water comes out the ,,,IN,,, valve side,, the canister is full,, and no air trapped inside
21/ now close both valves
22/ make sure the outside of the canister is dry,,, dont get the motor wet
23/ mount the can back on the motor and connect the other half of the valves together,,,making sure the IN is IN and the OUT is OUT
24/ open up all the valve halves
25/ turn it back on,,,, it might blow a little air fom the hoses,, once that comes out ,,,it is running
now you are right back where you started,,, except the spooge is gone
