03-25-2012, 09:51 PM
Was asked to do this picture tutorial by someone a week or so back. I absolutely keep my promises so therefore I am setting up this tutorial over how I clean the Fluval C Series Hang On Back Power Filter.

This will take 5 posts total and is 24 pictures in length. So, please hold off comments until the end (after I post 24 pics in 5 total posts).

Thank you.

The following tutorial will take place on the Fluval C3

Step 1, 2, & 3:

Remove HOB from back of tank, dump out extra water, remove filtration compartments, and impeller motor with a half turn of motor.

Step 4 & 5:

Pull out the water flow director from the housing and clean the housing.

Step 6, 7, & 8:

Hold the water flow regulator with one hand and a bladed tool with the other. Pressing into the finger grip area of the removable hatch cover, firmly press up with the blade, until the hatch cover moves out of the housing. This area will be undoubtedly will be gunked almost completely up. Clean this housing area out and move on to the motor. Pull out the impeller assembly and clean both the impeller and inside the motor housing. A pipe cleaner makes this so much easier.
Step 9 & 10:

Impeller blade comes off shaft assembly with a simple click. Taking it off to clean it out thoroughly is optional. Move on to the intake tube and clean with a hose brush.

Step 11, 12, 12a:

With the same brush clean out the main intake tube. This will not get into the u-joint area, a pipe cleaner with a small piece of soaked sponge will work ok. Feed the pipe cleaner through the tube and push the sponge into the tube. Fill the tube with water and pull slowly and firmly the pipe cleaner and sponge out the other side of the tube. Make certain the sponge is a really small chunk, or it will get caught.

Step 13 & 14:

Use the Pipe cleaner sponge or another pipe brush to clean out the remaining parts of the water diverter housing. Then reassemble the housing.

Step 14a, 15, 16:

Hold the Diverter housing and place back into the main Power Filter Housing, until there is a slight click. Reassemble the mechanical filtration compartment and place back into the housing.

Step 17 & 18:

Replace the Chemical filtration compartment and Biological filtration compartments back into the housing.

Step 19, 20, & 21:

While holding the main housing of the Power Filter place the Impeller motor back into the housing and give it a half twist to reattach. Then place the U-Tube back into the the main housing notch, with the extension tube attached to the U-Tube.

Step 22 & 23:

Place the Power Filter back onto the tank and fill with de-chlorinated tank water. Plug the filter in and adjust the U-tube to maximize the initial suction until the pump fully re-primes.

Step 24:

Replace the lid and adjust flow rate to your liking.

Thank you all for reading over this How To tutorial. It was a pleasure to do it as a favor to a community acquaintance. :22:

Special notes:
Make certain your using dechlorinated water to clean out the mechanical filtration and to final rinse any parts. This is so biological filtration isn't destroyed inadvertently.
