hybridtheoryd16;3485894; said:If you have a sump you do not need any other piece of equipment. Sump filtration is the best there is. It is just up to you to install the correct media to do the job you want done.
What media are you using for your mechanical filtration?
If your using a filter sock then get a smaller micron size.
If you have a mechanical pad of some sort then try to add some poly fill batting and pack it in that comapartment some what.
You can use cheap poly fill to catch what ever size particle you want. You just have to compact it more for smaller particles.
Some pics of your sump will help plan what you need to add/change.
+1 add some walmart batting and stack layers as needed.
