Aquaclear HOB for water polishing, Nitrate factory?

I used my 500 AC on my last tank. Superb filter and great flow but the sponge filter is a pain to clean. It does collect detritus though. Man, I can rinse it forever. I like the Regent type power filter, with the throw away vertical pads for mech. filtration, just because they are easy to pull out and clean.

As with any though, the sponge type, pads or the floss in a sump, regular disposal and/or cleaning is needed or the detrius is still in the system.
