What recharging ones are you asking about exactly? GFO, phosgaurd, poly-filter, and biopellets are all good PO4 removers.
Purigen works well, but not really for PO4, you will be better off buying some GFO from BRS than purigen.

I have used Seachem Phosguard and GFO in the past. Phosguard works ok in a filter bag but needs to be replaced frequently.....works quickly. GFO in a reactor (i.e. two little fishes brand) works for a month or so and I feel is the best chemical means of phosphate control.

50 gal tank 20 gal sump/refugium going in this weekend
some mushrooms, kenya trees, two clowns, 7 turbo snails , 5 hermit crabs, 2 spiny starfish, and other little critters I can't name (too small or too fast to really see)
ammonia 0 nitrate 20 nitrite 0 phosphate 0.5 calcium 400 carbonate 6 Ph 8.2 salinity 1.025 temp 78
Changing about 7 gal every other week

For a tank that size, I would consider running some PhosBan or RowaPhos in the Two Little Fishies Phosban reactor. I'm nit sure if Purigen with water flowing over/through it will really do the job well for 70G water volume. Purigen is also relatively expensive, and you should come out ahead in the long run using PhosBan.
On a side note, your KH may be a little low if it is at 6. I think that 8 would be a better number to aim for, although it should be corrected up slowly over the course of a couple of weeks.

I use the brs gfo and have been regenerating it for a little while now, works well without any issues not to mention the money your saving by regen yourself 
Only thing to watch out for is to not push too much water flow threw the reactor, you don't want the gfo fines in your water column, you just want the very top layer of gfo to slightly tumble in the reactor anything more can release it into your water and don't want that
