So after running this tank for about two and a half years, I figured it was about time I cleaned the sump..
Here's what I was up against.
I had planned to cleaned the sump a year ago but one thing led to another and well, here I am 
I started at 1pm today and finished up at around 9pm.  
So the first thing I did was pull out all of the equipment.  The skimmer, return pumps, heaters, probes, etc..  
Although I had not cleaned the sump in over two years, I was actually better at staying on top of the skimmer maintenance.  This is its second scrub down and vinegar bath in two years.
Shiny!
