Filtration question?

[FishyFishy!]

Realistically I would get rid of all of that junk and get a sump...

However, no that would not be too much filtration at all. What really matters is what you have in the HOB filter, and in the canister filter. What are you running in the HOB right now for media/carbon/filter pads etc? What type of canister is it?

Your best bet is simple, just take out all the media like bioballs, ceramic rings, or other bio media and replace it with live rock rubble, filter pads for mechanical filtration, and maybe some carbon. Should do the trick just fine.
