I just finished a water change. I noticed when I turned my HOB filter back on that I saw some tiny little white squiggle worms come out. Do I need to clean out the inside of my HOBs every so often? Also I think I have heard yall say that the worms are not to much of a problem. How is it best to prevent and or control them.

Sounds like you have got planerian. Basically these are harmless little critters that thrive if maintenance is a little lapsed. cap you will probably be there forever if you try removing them by hand, however reduced feeding for a period of time can often reduce their population. Do not clean your filter under tap water under any circumstances.

i clean my otbs once every 2 months only if needed take out your bio and put it in the tank that way your bio load wont die then clean it when u do a water change with your tank water
