Using Carbon to Polish Water

[Tooboot]

what about filter pads between baffles in the sump.

I had nothing but a Phosban bag there until recently. had an issue with my kid dumping some medicated water in the sump, and have since added a bunch of other filters to counter the effect the meds may have on my beneficial bacteria.

does any one have any experience and feedback to share on nitrate and phosphate removing pads, or a polyfilter?

i've recently added two small bags of carbon, poly filter, chemipure, nitrate and phosphate filter pads, cuprisorb. (probably overkill but the water looks good). what effect may this have on my fish (one clown) and inverts. there is also a filter sock and a BM nac 3.5 skimmer.
