Iwaki Pump Routine Cleaning

Here is the Iwaki WMD-30RLTXT that was replaced on the LifeReef skimmer.

Remove the 6 screws holding it together, and you can see the scum build up inside. I have no idea when it was cleaned last because I inherited this pump with the system.

Here, I've removed the impeller. More scum...

A quick rinsing and brushing with a toothbrush and all is back to brand, spanking new! I didn't even find it necessary to wash any calcification buildup with vinegar.
