I think if you have another tank running you should squeeze out some sponges/media from that tanks filters into your fx5 and fx6 media. This will seed them and help the cycle speed up.
You asked about purigen, I love it. I'll never run another tank without it. Replace all of your carbon with purigen. I use 10x the recommended amount. I also use pothos and two 3.5ft denitrate tubes DIY with seachem denitrate media. They are powered by 35gph mini pumps and lay on the bottom of the sump. My main tank has a massive bioload, this combination keeps nitrates below 20 even without a WC for 2 weeks.
A DIY k1 reactor 2 or 3 liter bottle would help too. Simple and cheap and very effective. You can see instructions on denitrate tubes and k1 reactors on YouTube.
Sorry for your loss, I know your pain all to well.
