Sorry dad, but it sounds to me like you're the victim of a shoddy LFS who just likes to sell you stuff you don't need. If you look at the tanks here, you will find that MOST run their tanks with NO filtration other than a GOOD skimmer, a sand bed, and copious amounts of good quality live rock. The filstar and skilter will continue to produce loads of nitrates, as will the filter tubes full of carbon. It's a biological filter process, no getting around it.
Please tell us more about your tank. What substrate do you have? How much live rock do you have? What kind of lighting do you have? Your Bak-pak is an OK skimmer for up to about 30 gallons, not much help after that. They are severely over rated by the manufacturer. PLEASE slow down on adding more livestock until you finish dealing with the ich infestation. That parasite takes 6 to 8 weeks of running a tank with NO fish in it to go away. That means setting up a quarantine tank to treat the fishes, while the parasite dies off with NO fishy host in the display tank. Treating your main tank with copper or most other drugs will pollute the live rock with copper, which will then leach back into the water for a very long time, and will kill most corals, anemones and other inverts.
We're here to help, and unlike your LFS, we aren't trying to sell you anything but success...and we'd be happy to "give" that to you...
